Maybe a forth hatchling!!

With many thanks to the staff at the MEC centre, I was able to gain access this afternoon to view the small black and white monitor that carries the live camera image of the MEC nest box. While the attending adult female was not about to give much up as to a great view of her new hatchlings that she is brooding, it does look like there are four hatchlings now in the nest bowl. All of the fluffy white chicks were huddled tightly together, and it was very difficult to get good head count. The adult female was not giving much up as far as a good opportunity to see much, but on one occasion she got up and walked over to the nest box ledge and gave us a short view.

Mark Nash reports:
Three hatchlings!!

I am delighted to report that we have been able to confirm that there has been a hatch at the MEC nest site. After spending several hours watching the nest box from both the street level and finally going to the nest box monitor, we can confirm the presence of three small white fluffy hatchlings. Congratulations MEC !!!

I will check again later this week to get another peak to see if the last egg will hatch.

Emma Stainton reports:
Spent some additional time this afternoon after school visit to take a look at the MEC birds. Hard incubation is still underway and no sign of a hatch as yet.
The adult female was sitting tight and sleeping, and showed no restlessness at all during my watch. While the black and white TV monitor that is hooked up to the camera doesn’t give the clearest views, it does allow a very close up look at the nest bowl and the incubating adults with in the box.
Fingers crossed that we should see evidence of a hatch any time now.

Emma Stainton reports:

At MEC today, I observed the female was incubating in the nest box. Whenever she got up to reposition herself, I was able to catch a few quick glances and was able to confirm at least 2 eggs, although it appeared that there may also be a third. No hatches as of yet. Whenever she did get up, after making herself comfortable she began to pick through the gravel. Also, she was clearly waiting for dinner as she had no visible crop and appeared to be keeping an eye out for the male. The female also preened herself and seemed for the most part, quite relaxed. Although I did also observe her vocalizing at something, perhaps other birds in the area (or the male). I went out to MEC #3 to see if I could spot the male and eventually did spot him high on the rooftop of MEC #1. He was most certainly keeping a close eye on me, but also made time to preen himself too. So, no hatches as of yet, but the pair seem to be doing very well.

Mark Nash reports:
Eggs are being incubated!!
We are delighted to report that the MEC peregrines are in fact currently incubating eggs in the nest box. Congratulations MEC!!
I was able to spend the better part of the day watching the MEC adults, and observed several changing of the guards while the pair were very active in their incubation duties.While we are unsure of the actual time of egg production and when full time incubation occurred, a stepped up monitoring will commence to watch for indications of hatch.

Lois Todd reports:
It appears we have a pair residing at the nest box on MEC1. I've been happily watching from my office's windows two Peregrines flying together, performing some beautiful moves (particularly on windy days). They often perch on the "Dejsardins" sign on MEC4. I guess it's time to bring my binoculars to work and start watching them!

Sunday March 25, 2007
Dan Suess reports:
Pair observed perched at #1 and #3 Robert Speck Parkway respectively. One atop the nesting area (at #1) and the other adjacent to the D of the Desjardins sign.

Mortality - Lynnette
It is with great sadness that I must report that Lynnette’s condition has not improved at all, as she has not responded to the emergency treatment. Her entire hind end was flaccid - she was unable to use her legs and had no righting reflex in the tail. She was treated her with steroid anti-inflammatory and fluids in an effort to bring down any swelling and to re-hydrate her but sadly there has been no improvement over the last 48 hours. After much consultation with two veterinarians involved with her case both agreed that euthanasia was the most humane option given the seriousness of her condition. Sadly, Lynnette was euthanized today.

Mark Nash reports:
“Lynnette” injured
It appears that we have more tragic news from the MEC nest site regarding another juvenile fledgling from MEC. The young fledgling named “Lynnette” impacted a window today in the Hwy # 10 and 401 area. Tracy was able to retrieve her and get her to the Toronto Wildlife to their downsview facility for emergency treatment. She has suffered spinal trauma due as a result of the collision with the building windows at approx. 7:45 am in the morning. Wendy has lost the use of both her legs and can not stand upright. Treatment was administered immediately upon her arrival in an effort to bring down any swelling that might be causing some of the problem. Sadly, this type of serious injury usually spells bad news. Her prognosis is not good at all. Given that this bird is not able to stand at all, she is forced to lye on her side (or chest), and with no rib cage to support her own weight, breathing at the best of times in this position is difficult as you can imagine. With our sincere thank you to the quick action of Mr., Lubomir Dzamba and all of his staff for rescuing Lynnette from the ground after the impact, and looking after her prior to our arrival.

Bruce Massey reports:
I had an opportunity to spend a few hours at the MEC nest site today to do a spot check on the three juveniles. While I was not able to clearly identify the individual birds by their name due to the distances involved, I had a delightful afternoon watching the three fledglings interact with one another as they were observed investigating many of the hi-rise building rooftops in the neighborhood. Both parents were involved at one point in the chase and pursue games that I witnessed.

Mark Nash reports:
Sadly, I was unable to get out to the MEC watch earlier, as I was out of town most of the day doing a speaking engagement in Nanticoke Ontario with both Falon and Alex. We all had a very busy day indeed after being on the road for more than six hours, fighting the constant traffic jams both to and from Nanticoke Ontario. Needless to say, despite all of the road work and distances that we have already traveled today, it was a very good day. A refreshing brake from the fledge watch, (as stressful as day it was as my thoughts were still focused on the watch and the potential havoc that could be going on) , it was nice to be with two members of our feathered family.

I am absolutely delighted to have been able to spend some quality time with Falon, and Alex of course. Falon spent most of the 3 plus hour road trip while traveling down to Nanticoke out of the carrier on the passenger seat beside me looking out of the car window at all of the scenes, and while I must admit that she is not much of a conversationalist, her body language throughout the trip down told me a huge story indeed! She roosted, preened, and periodically vocalized at me looking for a food hand out. I suspect that despite the fact that she would never have actually been interested in chocolate munchies I had, she was annoyed that I was obviously eating something, and she was not! Talk about a couch potato!!! Alex on the other hand, was more than happy to sleep in the darkness of her carrier as this time of the day is really her sleep time.

Having only just arrived in MEC at 5:00 pm, I quickly set up at my usual watch spot at MEC # 4, much to my delight, (and relief), I observed all three juveniles on the upper roof ledges of the nest building!! Over the course of the next 3 hours, I witnessed two of the three fledglings fly around the building, to the nest ledge and box, then back to the upper roof ledges. Now easily identified by their bright coloured red and white tape, it was much easier to identify who is who, (and who is missing) with the binoculars. Head counts and identification is MUCH EASIER!!

At the end of my watch, both Peter and Lynnette seem to be flying OK, and holding their altitude. They were starting to play with one another and were giving me quite a show indeed. They are learning quickly, and seem to be quite excited about their new 3-D world, as they are doing a lot of exploring!! We believe we have managed to get hem through the worst of it, and the rest is up to their parents.

The young juvenile - Julie was on the upper roof ledges of MEC #1, and although I did not see her fly, I suspect that she too may now be able to hold her altitude. The juveniles will be around the nest ledge for the next 90 plus days, as they are still very much dependant on their adult parents for food, protection, and of course MUCH training, as they are trained by their parents for the art of skilled flight, the art of pursuing, chasing, and hunting, an addition to actually catching food. The best of the best is still yet to come as far as incredible viewing and observations! This is the best stuff!!

Shortly after 9 pm, the cell phone was ringing again, and I was forced to leave the MEC watch to travel across the city to pick up an injured falcon in Scarborough Ontario. I dashed back to the Vaughan to the CPF raptor centre to return Falon and Alex, and proceeded to the east of the city. Upon arrival, the bird turned out to a recently fledged Kestrel, one that had Been grounded for the past 3 days. After it was examined for injuries, we fed the little guy. While although still very aggressive, he willing took the mouse meat that was offered. I advised the good folks that had been caring for the bird to return it at daylight the next day to the spot that it was found, (in a safe elevated spot) allowing its parents to find him and take over. Home early by midnight.
Stay tuned……………

Mark Nash reports:
A much better day to report in comparison to the tow previous days. While the wind is still relentless, the heat and humidity was much better to tolerate today, and the constant breeze was actually welcomed. Upon my arrival, I quickly focused my attention to the nest box and ledge, and please to report that Julie was still on the nest ledge hanging around nest box. It was obvious that she had not taken her first flight.

I then quickly focused my attention to the canopy rooftop at MEC # 1 to look for Peter, who I was held up on the canopy roof at darkness last night as I left. Much to my surprise, Peter was found BACK on the nest ledge elevations several ledges west of the nest box. He had obviously made it back to the ledges on his own early in the morning before I got there.

Lynnette was found on the upper roof top ledge on the west site of MEC #1. She had obviously found her way up to these ledges from the roof top where I have released her last night.

All was quiet for the most part of the day, until 8 pm. Mom was observed on flying into the south side upper ledges of MEC #2 with a food package. Looked like a white coloured pigeon, as it was a very large package. She proceeded to pluck (de-feather) it, while occasionally taking a few bites for herself. She then flew over to the southeast corner of the MEC#1 and landed. That’s when the fun started. With much vocalizing from Julie and Peter, Julie attempted to hop over to mom, and in all of the excitement, slipped off the ledge, and down she came. Not a good maiden flight as you might expect, pushed by the wind, she ended up crashing into the glass of the building while trying to get altitude and return to the nest ledge. She bounced off the windows, dropped several more floors, and again did a face plant into the windows. At this point, I though that she had been killed as her wings folded up, she dropped straight down15 plus floors to the pavement at ground level.

I rushed from the rear parking lot of MEC #4 where my vehicle as parked, abandoning everything in an effort to get to her as soon as I could. With my heart (and lungs) throbbing as I arrived at MEC #1, incredibility, Julie was located standing in and upright position on the sidewalk outside the BMO suite windows at the south west corner of MEC #1. Un-hurt, slightly scuffed over the right eye, she charged directly at me!!!! Thank god for my coat in hand that protected me, as she literally attacked me! (Like I was responsible for her fall)!!

She was quickly captured up in my coat all in the same motion as she latched on to my pant legs during her charge. Talk about being peeeeeved ! She was then carefully examined for other injuries, and was then placed in the rescue box that MEC security has been kind enough to store in the fire room for us – for this very purpose. Julie was left in the fire room in the cool quite until darkness, when she will be examined one more time before being released to the roof of the nest building.

Moments after I arrived back outside, Lynnette was observed in flight, - (sort of), with wings spread being lifted by the wind just like a kite from the nest ledge elevation where she had been roosting. Wings stretched out, wobbly and no flapping at all!! She was lifted by the wind to the upper roof ledges – northwest corner of MEC#1 and disappeared from my view atop of the roof area. I searched the north areas around MEC #1 but she was not seen again during my watch.

At darkness, MEC security assisted me with the release of Julie back to the roof of the nest building – (MEC#1). As with Lynnette the day earlier at her release, I applied a small piece of coloured tape to her USFW band, to make it easier for us to identify each of the birds without having to use a spotting scope. Julie got a WHITE PIECE OF TAPE, and Lynnette was given a RED PIECE OF TAPE on her USFW band. They both still have their solid black bands on. With at the heights that the birds are at, there is no way you can read the digits with a 75 plus power scope, and lots of time, and this coloured tape will make it MUCH easier to ID the birds.

This will make it easier to both identify and keep track of the fledgling as they are flying around. The MEC buildings are very tall indeed, and it is impossible to identify the birds without a spotting scope, and even then it is almost impossible unless you are very close. With this coloured tape being so visible with the sue of binoculars, even one person can identify the birds, making it much easier to tell if you have a missing or lost bird. Photos included with this report.

Stay tuned………

Mark Nash reports:
If you like lots of sun light, 75 to 80 plus degrees, very hot humid temps, with the humid X above 30% mixed in with some smog, than I would say today was a very good day indeed! Despite the brutal heat and humidity, it was actually a very good day for peregrines today. Due to the 16 hours I have spent in the streets today, I will be very short with my report, as its after midnight, and I will be out on the streets again tomorrow by 5 am.

With the incredible day long winds from the North West, blowing all that hot air around, the two remaining juveniles survived another day. For the most parts of the day, the two juveniles were not very active at all, as they sent most of their day lounging around on the nest ledge and nest box. I guess the heat and humidity was having the same affect on us all. I spent several hours searching for the missing fledgling that disappeared from my sight line yesterday on its maiden flight. The 75 power scope proved very useful today, as I was able to clearly identify the remaining two chicks on the nest box. Peter and Julie were identified by their band numbers. Lynnette was the one missing from the day before, and is still missing.

Just as I though that the rest of the day would be quiet, around 3:10 pm, Lynette suddenly started flapping as she ran from the nest box out onto the ledge. At this very moment, a huge guest of wind literally swept him off of the ledge as if he had been shot out of a canon. Down he came, pushed by the wind, flapping as hard as he could. As he crossed over to the south of Robert Spec parkway, he managed to turn north and cross back over to the north side of Robert Spec towards MEC #1 – (the nest building). By this time he was almost at ground level, and amazingly he was able to land on the covered area in from of the entrance of MEC#1 – about 18 feet above ground level . I quickly packed up my scope and tripod, got into the car and drove to the west parking area of MEC #1, and parked. She certainly was confused as he ran back and forth the roof ledges of the over head canopy for the next few hours. Finally at 7:30, he finally ran out of steam, and settled down on the roof of the canopy.

At approx. 6:50 pm, and much to my surprise, Lynnette was observed walking towards my parked vehicle – walking on the side walk on the west site of MEC #1. As I quickly scrambled to collect the towel, take my sun glasses off, put my binoculars down and open the door to get out to the car, Lynnette had walked/ traveled literally to the base of my driver’s side door. As I sprang out of the car, she was at my feet. Needless to say, we were both quite shocked to see each other so close. As she froze, I grabbed!! Absolutely the best, quickest capture up I have ever experienced!! After a through examination, she was placed in the rescue carrier and held for release until dark. She was later examined before release and was placed back onto the nest building roof top by 10 pm.

As I packed up to leave, Peter was still laying down almost asleep on the upper canopy roof in front of MEC #1 where he had landed hours before, Lynnette was on the upper roof of the nest building, and Julie remained in position on the nest box.

A big thank you to security for assisting me to get Lynnette back to the roof! Photos of Lynnette and Peter were taken at the time, and available for your viewing on the MEC nest site photo gallery

Mark Nash reports:
I had reported several days ago that one of the Etobicoke watch days was the day from hell, but I stand to be corrected. Extremely hot & humid, muggy and no place to hide from the sun! This was the best part of the day, as we had to deal with yet another death today. Paula, one of the juveniles took her first flight today and it ended up in disaster and mortality. Sadly, on her return to the nest ledge on her maiden flight, the tail wind was simply too much for her inexperience and pushed her ever so faster forward. It was simply too much for her to control her speed, and despite her mom’s efforts to steer her away, she collided with the building and fell a dozen floors down the glass to pavement at ground level. Paula was retrieved and boxed and held by MEC security out of the heat until we packed up at the end of the day.

Just after 7:00 pm, the second juvenile took flight, flying to the south east, again pushed by the tail wind, and again with both adult parents in the air at her side. They managed to steer her around back north into the wind but she simply couldn’t hold her altitude and ended up to the north beyond our view in the tall trees down in the valley. After almost two hours of searching, we were unable to locate her position. As darkness fell, the last two juveniles were observed roosting quietly on the nest box. The one little hatchling believed to be Peter, the only male still has fluff on his head and was cautious even to come out to the nest box porch, while his remaining sister was roosting on the ledge of the nest box porch looking quite confident.

We suspect that the one will attempt it first flight tomorrow, and be back at 5 am / first light to be in position. Photos have been submitted of Paula to show you what happens when peregrines meet glass at high speed. A sad day indeed.

With thanks to Emma and her recently recruited boyfriend who toughed it out in the heat, and Marion by my side throughout the ordeal.

Mark Nash reports:
Once again this afternoon, three of the hatchlings were observed out of the nest box running around and both playing and exploring on the ledges to the left and right of the nest box. The adults came in several time over the 4 hours that I was there to feed the chicks. The forth chick, believed to be the same one I observed yesterday in the nest box did not show itself until the very end of my watch. It did not show any interest at all when the parents brought in food to its other three siblings. Not much flapping going on today at all, but three of them were very active exploring the other ledges to the west of the nest ledge. They are getting bolder, and seem to really enjoy this hid and seek game with each other. Quite a sight to see these birds playing like this.

I closed the watch in the evening just before dark, as the birds had returned to the nest box. Still no flights today, but we are getting very close to a fledge. Most of their fluffy down is gone, and I suspect that we will have a fledge on the weekend.

Wednesday June 14, 2006
Mark Nash reports:
Several hours were spent today at the MEC nest site spot checking the birds. Surprisingly there is very little activity at this nest site today. While three of the girls are very mobile, now out of the nest box, there is very little flapping going on. They have although learned that they can drop below the back of the nest ledge to get some shade and a cool spot from the sun. They run under the nest box and pop up onto the nest ledge on the other side of the box. It appears that they are making quite a game of it. The forth hatchling is still in the nest box and doesn’t seem very interested at all in his siblings activities, and given his/her behavior, I know that this little guy/gal may be a challenge at fledge time, and one to watch very closely.

I can’ believe at the amount of food that the parents are bring in during my observation time today, as they have been in seven times with small food packages for the hatchlings.

Tuesday June 13, 2006
Mark Nash reports:
Arriving in the later afternoon, we were faced with the terrible thought that one of the hatchlings had already fledged prior to us getting there. Three of the hatchlings were very visible, two running around on the nest ledge, and a third was very active in the nest box. The juveniles have learned to jump off the nest ledge, and are able to run under the nest box to the other end of the nest ledge. Scary from our view from ground level, as they are constantly missing from view as they jump down behind the nest ledge and out of view. One second they are there in your view, and literally at the blink of your eye, one or more are missing!! Needless to say while one of us stayed glued to the nest ledge and nest box, the other searched the valley and creek area for the missing forth hatchling! After more than 5 hours of combined ground searching, and dissecting every tree and every tree branch, and every patch of ground we could get at, we were not able to locate the missing hatchling. During this entire period, mom flew in on two occasions to feed the three juveniles on the nest ledge and in the box. As darkness closed in at around 9:20 pm, we gave up hope and started to pack up the spotting scopes, tripods, and bins. Just as I was putting the last pair of bins away, I focused one more time on the darkened nest box only to see the four juveniles at the box!!

A very frustrating evening to say the least, panic stricken that we had lost one at this site, (while still mentally trying to deal with the mortality already experienced at the Etobicoke Clarica centre nest site yesterday, I can’t tell you how relieved we were to see all four juvi’s at the nest box safe and sound. While all of the juveniles were active running around, not much flapping was observed at all, and all have allot of while down still on them.. We are still s few days away from fledgling it would seem.

Banding Day!

A great day indeed! Assembled in the lobby of MEC 1 again this year, and everyone seemed every bit as excited as I was. With many thanks to Oxford Properties, Sky Reach and our good friends at the Ontario Ministry of Natural Resources, along with some 100 plus attendees, the banding went without a hitch again this year and was a great success. This year’s 4 hatchlings were as feisty as ever, and included 3 female hatchlings and one male. Many photos were taken by several photographers this year, and you can see them all in the 2006 MEC nest site photo gallery.

We were all delighted to have some special guests in attendance as one of the local schools attended this year with class of children to both witness and assist with the banding event this year.

For the most parts, the banding went without a twist, - with one small exception. While the banding went routinely, the adult peregrines made sure that the event was a memorable one for the crowd as they gathered outside of MEC 1 to watch the young hatchlings being removed from the nest box. With the swing stage in position, after having been lowered down from the roof to the nest box, the resident adult female showed her displeasure by stooping John, a biologist from the OMNR, and grabbing his MNR hat right off his head. The adult female then carried the hat across the courtyard over to MEC # 3, and dropped it just short of the roof top ledge. As the hat fell from the sky down the side of the building, both resident adults joined in a chase for the hat as it fell to the ground level.

I guess they vented a little of that good old peregrines attitude at Johns hat. Better the hat than his head!! The peregrines hatchlings were returned to the nest box no worse for wear, and settled down back to life as usual, much to the delight of the adult peregrine parents!

The four hatchlings were named: Peter, Lynnette, Julie and Paula.
A huge thank you to the Oxford properties management group and the MEC staff for making such a great day!

Mark Nash reports:
4 hatchlings confirmed!!! Once again, a little stressed with the many ongoing activities of the season, (and a very busy time indeed), I am happy to report that we can confirm that there has been a hatch at the MEC nest site!!

I attended the roof area of MEC #3 this afternoon and I was able to confirm the presence of four hatchlings in the nest box. Given their size, (and with mom doing her best to conceal the four hatchlings in the nest box) I believe that they are about six days old given what I was able to see – (and photograph). This would put the hatch on or about May 3rd or 4th /2006.

Dad, or (Sal as he was named, having been produced at the Hamilton nest site in 2001) was observed in person, and up quite close, (clearly identified by his band number), as he visited me on MEC 3.

Mom, and un-banded adult female, - (different to the adult banded female from last year), also paid me a visit, and while she was not vocal, - she did stay in my face – literally, for over an hour! Sal took over brooding activities in the nest box while the adult female took up position several feet from my observation position on MEC 3. She roosted, preened, and gave me some very nasty looks for over an hour while roosting not more than 3 feet from where I was sitting. During this time, I was able to snap a close to a 100 photo’s with the digital camera.

About an hour and a half into my observations, she obviously had enough of my presence, and made it very clear that I had overstayed by welcome by flying directly at my head, grabbing and removing the CPF base ball cap from my head, and carrying it off the roof top, where she released it mid-air several feet from the edge of the roof top. At this point I packed up and made a very hasty departure!!

I was able to recover my CPF cap upon my arrival at ground level while on route back to the car. Other than a few new holes, no worse from wear.

Mark Nash reports for Maya Basdeo:
We have Eggs!! (April 2nd)

Apologize for the lack of updates, as it has been a very busy spring indeed with peregrine season in full swing. There is much activity everywhere as you can imagine given the time of year. I am relaying Maya's observations on her behalf:

The MEC peregrine nest has been very active indeed these days, and while we are behind in getting our update into the CPF web master, we can confirm that the pair is currently down on eggs, as the pair is well into full time incubation mode. Both Maya and Bruce have been spot checking the activities of the adults, and have confirmed that full time incubation is underway as of May 9th, with the likelihood of the first egg(s) having been laid April 1st or April 2nd. Maya was able to confirm the presence of at least three eggs in the nest on April 9th, with the likelihood of there being four eggs. We are expecting a hatch date around the middle of the first week of May. Our fingers are crossed that there is a successful hatch again this year!

Lois Todd reports:
I was coming back from lunch today when a crow flew by my building at 1 Robert Speck Parkway. A Peregrine immediately charged off the ledge at the top of the building and gave chase. They did some aerial manoeuvers around the Mississauga Executive Centre buildings before the crow flew off south. The Peregrine gave up at Burnamthorpe and returned to the ledge. I haven't heard of any nesting activity, and if the Peregrine had been after food, the crow would probably not have escaped, so I can only assume it was "fun".

Thursday September 1, 2005
Mark Nash reports:
With fall just around the corner, reports have been streaming in that things have got very quiet at many of the urban nests sites, and with the absence of the juveniles, it is nice to see at least that many of the urban adults are still on territory, with reports of many of them still spending time on the nest ledges.

Now independent, and hunting on their own, it would appear that many of the juveniles have either moved on, or have dramatically expanded their hunting areas taking them farther away from the home territories. We remember years past, while very closely monitoring some of the peregrine nest sites, we witnessed the adults on more than one occasion actually chasing their offspring out of the territory as October moved in. It is believed that the adults reach a point that they will simply no longer tolerate the harassment for food from their offspring, (in addition to sharing the territory with the kids), and "encourage" their young to move on. Sooner or later, the urge move on overwhelms them, as in the peregrine release sites that we have been doing over the years, the juveniles simply stop returning to the hack boxes for the food being provided by the hack site attendants.

Bruce Massey reports:
With what happened last week, with the little male taking off and not being seen, I decided to do a sweep of the area. Therefore, I walked north to Rathburn, South of Central Parkway, West on Mississauga Valley, and then north on the West side of Square One and back East along Rathburn. Over all this took about five hours, but with lunch and breaks it was probably about four hours. During this time, I saw a) An immature female kiting over Robert Speck Parkway and circling up in the clouds until I lost her, and in the Kaneff antenna, a possible hit on the missing male (however, by the time I got closer the bird flown away. ) and an adult flying in the vicinity of the nest building.

Guylaine Drolet reports:
7 PM to 9:30 PM

As I was driving South on Hurontario street, approaching the MEC buildings, I saw a juvenile chasing a bird right above my car. It was flying N. I parked my car at MEC #3 and started my rounds. Nothing... Made my way behind MEC #2 facing South. Stayed there for quite a long time. Nothing... Walked around the buildings again and made my way to back the same spot behind MEC #2.

Around 8:30 PM, I was coming back towards MEC #3 when I finally spotted the juveniles and another bird. This other individual took off to quickly for me to be able to establish if it might have been Ox or not. I lost sight of that bird but continued watching the girls. They were at the condo's N of the MEC buildings. They were having a blast, soaring together, chasing each other. It was truly a pleasure to see them doing so well.

Suddenly, Sun flew towards me, as I was focussing on her, I lost sight of Mecca. Sun flew right between MEC #1 and MEC #3 where all hell broke loose. I was able to see 4 birds in attack mode. I thought that maybe OX was back and that they were chasing after him. From where I was standing, they flew below the tree line and I heard a horrible scream. I started running towards where the commotion took place. When I got there, I spotted an adult perched E on the CIBC building. Then a minute later, I saw Sun land on the E corner of MEC #1 with prey, she quickly took off and flew the her dinner table, MEC #1 S corner where she proceeded to eat her meal. After she finished her dinner, she flew off to MEC #3 and then took off again. I didn't see where she went. Didn't see where Mecca went either. By that time, it was getting dark, what a night!!! Sure hope that Ox is doing okay.

6:15 AM to 8:45 AM

Arrived at MEC. The girls were already up and about. Took me a little bit of time to finally spot one juvenile and an adult. These two seemed to fallow each other. Perched on the same building, then, about 20 minutes later, changing location. All I saw while I was there was these two birds. I really don't think that Ox's in the area. Will try again later.

2 PM to 6 PM

Back at MEC. Upon my arrival, I immediately spotted one adult perched on the Kaneff antenna and a juvenile perched in the shade on top of a window pane facing East. The reason I decided to go at this time of the day is because it was so hot, I figured that the birds wouldn't be very active and that way, I could walk around and try to spot the other family members.

I was right, these two birds did not move for at least 3 hours. I walked around all the way to Hurontario and looked everywhere but didn't see any sign of the others. Around 5 PM, the adult took flight and landed on the adjacent window pane close to the juvenile. The juvenile took off and I lost sight of her behind the trees. Since I just couldn't take the heat anymore, I called it quits at 6 PM.

Mark Nash reports:
Little Ox has returned from OVC and is ready to go

After meeting with Mark Heaton from the Aurora district of the MNR this afternoon on the 407 to transfer "Linda" (one of the young fledgling peregrine falcons from the Toronto Sheraton nest site), we scheduled yet another meeting for later that evening, as he had some good news regarding "OX" (one of the injured juvenile peregrines from the Mississauga Executive Centre nest site). After having been treated by the Ontario Veterinary College, Small animal clinic, he was finally being released from their care and transferred back to the MEC nest site this evening. After suffering a dislocated jaw when he collided with one of the MEC office towers, he is now ready to be returned to his siblings and family.

Under the cover of darkness, at around 10 pm, I met with Guylaine and Mark Heaton at the MEC nest site, and with the help of building security, we were able to release OX back to the MEC 1 nest building roof top.

As usual, nothing with these guys happens as planned. After more than 14 other releases this season (so far), successfully using the cover of darkness for a release time (preventing the young from flying off the roof in panic - due in part to the cover of darkness) - the unexpected happened!
Ox took flight right out of the carrier, flew south east, and disappeared into the darkness!!!!
While I must admit this bird had no problem with his flight, and he gained altitude like a F-16 jet, it was a little disturbing to see this happen.

Guylaine, on the other hand, had been on site since the early evening, and had many sightings of the two siblings and both parents. Just as I arrived, at approx. 9:15 pm, she pointed out that one of the adults was in the middle of feeding the two female juveniles on the upper corner of MEC #1.

Stay tuned..........

Guylaine Drolet reports: 8:30 PM to 10:30 PM

Upon Ox's return/release at the MEC site, I decided to go to the watch a bit earlier to see how the girls were doing. It didn't take me long to spot them. By the time Mark Nash arrived, Mecca and Sun were perched on the S corner of MEC #1. Both very content with their full crops. They were settling for the evening.

Around 9:30 PM, Mark Heaton arrived to MEC with Ox. Shortly after, Ox was released on to the roof top of MEC #1. He took a panic flight didn't know where he was at. Shortly after, I spotted him perched on the SW corner to MEC #2. He stayed there for about 10 minutes. He then took off to an unknown location. Unfortunately, we didn't see him take flight.

Ted Perz reports:
I was fortunate enough today to observe a pair of peregrines for 68 minutes at 10 Kingsbridge Garden Circle. This is the taller of the two buildings that comprise the Emerald Centre, on the west side of Hurontario, one block north of the 403. My vantage point is a 15th floor condo across the street, to the west. I use a spotting scope with a 15-40 power zoom eyepiece. The viewing distance is about 180 m (600 feet). The roof of 10 KGC is a popular roost for pigeons and starlings. The edge is bounded by a low parapet of about 25 cm (10") height. At severals places the parapet extends upwards to a total height of about 55 cm (22"). My view of most of the roof surface is obscured by this parapet.

17:59 - The calling of an adult was the first thing to catch my attention. It was flying in a northwesterly direction above the intersection of Kingsbridge GC and Tucana Court. Moments later I saw an immature on the high parapet on the west side, with dinner firmly in its talons. The pigeon must have been killed moments before, as it was still almost completely feathered. As the immature falcon alternated between plucking out feathers around the neck and pulling off pieces of flesh, strong winds were pushing them along the parapet. A couple of times, I was sure they would both be blown right off the roof.

18:12 - By luck, or perhaps by design, the falcon finally dropped its dinner onto the roof, and hopped down to continue its meal, out of the wind ... and my sight. For almost half an hour, all I could see were the tufts of feathers, that were being occasionally blown over the side.

18:40 - The immature falcon reappeared on the low parapet, without the pigeon.

18:41 - The adult landed nearby on the high parapet with much ensuing vocalizing, which I could plainly, hear, despite the traffic noise and the 180 m distance. Moments later, it had gathered the remains of the pigeon and retreated to extreme northwest corner of the parapet. The adult continued its squabbling while eating what was left of the pigeon.

18:52 - Half of the remainng carcass broke off and fell to the ground, whereupon the adult flew off and landed moments later on the north low parapet.

19:03 - The adult flew off to the north, did a clockwise "victory lap" around the building and continued out of sight to the northwest.

19:07 - The immature, who had remained quite still while the adult had been eating, departed in almost the exact same manner as the adult, complete with "victory lap".

Ted Perz reports:
At about 8AM, an immature Peregrine landed on the southwest corner of the roof of the Emerald Centre (10 Kingsbridge Garden Circle), where it was harrassed by a Ring-billed Gull. It stayed for no more than five minutes.

Bruce Massey reports:
Upon arrival at Mississauga, I easily found the two adults, but it took me an hour to find only one of the immatures. That bird was on the north side of MEC Two. This was not unusual, due to the fact that hours I was around there was at about 1130Hrs to 1230 Hrs. which of course are some hottest hours of the day.

Guylaine Drolet reports: 2:15 PM
All is well at MEC. Another very hot day today. The girls are keeping in the shade, staying put. Sun was perched on top of the nest box and Mecca was around the corner perched on MEC #1 facing NE. Mecca actually had one of her legs extended with her foot sticking out...

4:15 PM
Upon arrival, I was delighted and relieved to see Mecca and Sun right at the nest ledge. Today was another very hot day and the girls didn't move much. I only stayed for 1/2 hour and decided to come back later to see how well they both fly.

Got back around 6:30 PM, Maya and I looked around, Mecca was at the nest ledge and Sun was off with dad at their new hang out spot, the radio antenna on the Kaneff building.

See Maya's report for more details on tonight's watch. I will say this, Mecca did not move from the nest ledge. She got fed. She took a nap, flat on her belly. We did not see her fly tonight. Sun was all over, she's doing very well.

I will try to stop in again tomorrow to see how well Mecca's doing/flying.

7:45 PM
I was sure that MEC would be a quick check. Was I ever wrong. Upon my arrival, no-one was home. Not a "peregrine" in sight. It was so quiet. I started doing my usual rounds. Walking around the buildings. First, MEC #3 and checking everywhere, roof tops, ledges, ground, MEC # NE side. Nothing.

I then proceeded to walk around MEC #1 (N) in the back. Carefully looking everywhere to try and spot these birds. Finally after a good 1/2 hour. I was walking south on Hurontario and I saw a juvenile chasing an adult. They were flying around and above the Kaneff building. They both flew over to the large red and white radio antenna and perched. The juvenile took off, did a nice turn around and landed very close to dad making him take off. Dad then flew back and perched him self to the highest spot he could find on the antenna. I saw him stoop twice. These two were on the hunt. Trying to keep them in my view, I decided to walk around MEC #2 and MEC #4. Still no sign of the other juvenile. As I came around the corner from MEC #4, I saw mom perched on the SW corner of MEC #3. She stayed there for quite a while. At this time, I don't have a visual of the other 2 anymore.

The sun was setting, the street lights were on. I was hoping that the 2 girls would come back to the nest box for the night. Mom suddenly takes off I saw her gliding low. She perched on the corner of a smaller building not far from MEC #1. A couple of minutes later, she flew back to MEC #2 and sure thing, there was a juvenile with her. Was it the same bird I saw hunting with dad earlier? Can't tell you. This juvenile goofed around on MEC #2 for a good 10 minutes, running on the ledges... Then she flew over to the nest box and that was it for her. I never saw another juvenile. I'm not sure if the juvenile that Mark Andrew saw yesterday is the same one I saw today. So, at this time, I'm going to assume that I'm missing a juvenile. I shall go back tomorrow and hopefully, I will see both Mecca and Sun simultaneously so that I know that they are both safe and doing well.

Mark Noseworthy reports:
2:15 pm. – 3:00 pm.
As I started walking around the buildings, none of the birds were in sight. Going along the west and then north side of MEC#1, an adult, coming from the east, flew right across my field of vision and then turned south to go over the building. I continued my walk around the building, still searching for the juveniles, and was then back in front of MEC#1. The adult was on the second-from-the-left (i.e., West) bank of windows on the south side of the building. It was still there at 3 o’clock, when I left to go to Etobicoke. Except for a couple of seconds of kak-ing as I walked south along the east side of the building, I heard nothing from the adults or juveniles.

5:15 – 6:00 pm.
When I arrived, one of the juveniles was on the leftmost bank of windows on the south face of MEC#1. She stayed there the whole time. I walked around for the 45 minutes, trying to locate the second girl. Right away I had seen something out of place on the east side of MEC#1 – up against the building wall, there seemed to be a dark lump or ball of something, but I really couldn't see it very well. I presume (and hope) it was feathers I was seeing, and that this was the second juvenile, because I didn’t see anything that looked more like a bird during my stay. During this visit, neither of the adults were visible. I heard no vocalizing from any peregrine either. Perhaps the small amount of flying and little sound is because of all of the intense heat the past couple of days? I certainly paid for moving as much as I did.

Guylaine Drolet reports:
Located mom @ MEC #1 NE - same level as the nest ledge. Shortly after I saw dad @ MEC #1 a few ledges left from the nest box. Mecca's roosting on roof top ledge of MEC #1 S side and I finally see Sun at the nest ledge. She's being very vocal.

4 PM - The male brings a small snack to Sun at the nest ledge. Mom is soaring above MEC #1. Mecca seems oblivious to the fact that Sun just go served a tasty meal. But not for long! She's on the roof top ledge and is now "walking" her way towards the nest ledge. And eventually she turns around and "walks" back towards the S corner, near her dad which is now perched below her.

4:14 PM - Sun takes off from the nest box and does a quick right turn and flies straight up to the S corner of MEC #1 where Mecca is now roosting. Sun's kacking at Mecca, does a quick "fly-by" a soar and then she flies right above where I'm at over towards MEC #2. I lose sight of her and start running/looking for her. A few minutes later, I see her - she landed on the roof top ledge of MEC #1 and the 2 sisters are re-united.

4:30 PM - Mecca gets served her late afternoon snack by mom. Not sure where Sun's at? The whole time that she's eating, mom is soaring above, doing some quick fly-by's, many touch and go's. And quite a few landings near her daughter.

4:50 PM - Both adults in view, Mecca's still on the roof top. Don't know Sun's whereabouts at this time.

5 PM - Both sisters are roosting on roof top ledge of MEC #1 S side. Maya joins me.

6:10 PM - Maya and I have been watching at different posts for quite a while. The girls have been behaving themselves. I have a little snack to offer Maya, so I called her to tell her that "I'm on my way" to join her. Sure thing, as soon as I join Maya, Mecca takes off from the roof top of MEC #1 and flies all the way to the roof top of one of the Rathburn condos. She kept very good altitude and landed fairly well. A couple of minutes later, she flies right back to MEC #1, she really did well and adjusted her speed, landed on the same ledge as Sun. The girls are together again. Kisses and greetings are in order.

7 PM - Mecca's on top of the nest box. Sun's @ MEC #1 mid way N ledge. Dad s @ MEC #1 at the very NE corner and mom's @ MEC #2 on top of the building NE corner. Will they bring another snack for the babies?

7:15 PM - Mom takes off, flies over to Sun's ledge, does a quick touch & go. Mecca's gets up, she's standing really stretched out almost like she's standing on her tippy toes. Very curious of what's going on. It's really funny, I now know how to tell who's who when they are standing near each other and we can't see the red tape on Mecca's right band. Mecca's leg feathers are much lighter/paler than Sun's. It's almost like she's wearing pantyhose or something. Maybe we should nickname her "Mrs. pants." hehehe.... And to confirm all this, I finally managed to see the red tape on Mecca's leg band.

7:40 PM - Mom's back but no food. Dad, on 3 separate occasions, did stoops at birds who would fly near him.

8:30 PM - Both girls are @ the nest box. Maya saw dad fly towards Hurontario and Burnhamthorpe and Mom joined him. It must be hunting time. It's starting to get dark, the girls are patiently waiting.

9:30 PM - The street lights are on, mom and dad have not returned to the area. The girls have tucked themselves in. Maya and I concluded that mom and dad have gone out on a late dinner date together. After all, there's no need to worry, they have 2 baby sitters watching their babies. The parents must have decided to start keening their girls so that they can start hunting training very soon.

Maya Basdeo reports:
At around 3pm I received a phone call from Marion at CPF Head Office that a peregrine was down at MEC and was already in a rescue box. On arrival at MEC 1, Guylaine was waiting for me along with the lady who saved our bird. Upon my arrival, the young juvenile female was removed from its carrier, along with Guylaine's help , it was checked her over for obvious signs of injury or trauma. We are pleased to report that no serious signs of trauma was apparent at this time, but concerns regarding a very small amount of fresh blood was observed in her mouth. The young juvenile female was identified by her silver leg band as being that of the bird named "Mecca". She was put back in the rescue box and spritzed her in the mouth with a little water , and held over in a quiet cool location provided to us by MEC security until the CPF head office was again contacted to update them of the situation . I spoke to Marion, and then shortly after to Mark Nash. Although the bird did not appear to have sustained serious injuries, she seemed to be quite puffy over her breast area and I had never felt anything quite like it before.

After consultation with the Dr. Markus Luckwaldt D.V.M.,an avian vet at the Amhurst Veterinary hospital, and on his advise, it was agreed to hold Mecca over, and wait until Mark returned from the Brockville Hack Release site so that a further re-assessment of the bird could be done before she was released back to the roof.

I proceeded to the Etobicoke watch while Guylaine stayed in Mississauga to keep an eye on the last chick in the nest. Later that evening , Mark, Guylaine and myself met at MEC 1 to further assess the bird. She appeared healthy and the puffiness I was worried about turned out to be baby fat and down. No wonder she came down! Mecca was re- released back onto the nest building roof under the cover of darkness to prevent her from bolting off the roof top while being released. I'm sure the next time I go back to MEC and a bird stoops me, it will be her !!

We would like to send a very special thank you to Mary, who's calm and decisive actions saved Mecca's life. Great job!

Guylaine Drolet reports: 3:15 PM
Upon arrival, walking towards MEC #1 to go check on Mecca in the carrier, I made sure to get take a few minutes to get a visual of Sun on the nest ledge Sure thing, the "little" sister was resting right by the nest box. See Maya's post for details on Mecca's observations.

Maya decided to go to the Clarica Centre to help with the Etobicoke watch. I stayed put to keep a watch on Sun.

For most of the afternoon, the adults didn't do much. Dad was perched right at the S corner of MEC #1. Didn't see mom for quite a while. Later, I decided to take a walk around the buildings, that's when I located mom. She was perched mid way on MEC #1 facing south. Actually just a few ledges away from her mate. These two are pretty tight. They never seem to be very far from each other for too long.

Around 4:30 PM - Sun was getting a little hyper, it must have been weird for her to be all alone at the nest ledge for so long. She was flapping her wings. At one time, it looked like she was playing at the nest box. Then she began to settle down and started a preening fest. It was very funny to me because every time I looked at her with my bino's, it looked like she was headless...

6 PM - Both parents took off. It must be dinner time! About 25 minutes later, dad returned to the nest ledge with a very nice size meal for his daughter. Mom flew to the nest ledge and immediately took off. Dad proceeded to spoon feed Sun a few bites and then he flew off to keep watch on Sun at he's post on the S corner of MEC #1. Sun took a good 15 minutes to eat her dinner and with nobody to share this meal with, let's just say, she looked quite full and content. Needless to say, she was set for the evening. Shortly after this she tucked her self in and that was it for the night.

Mecca was later released on the roof top of MEC #1.

Maya Basdeo reports:
Before heading to MEC I spoke to Mark Nash. He had an update on Ox - it seems the X-Rays done at OVC show he has a dislocated jaw. His treatment is being discussed and the results of the blood work have yet to come in. It is our hope that Ox's stay at OVC be as short as possible. He does not fly well yet, which is obvious, and is still completely dependant on his parents to feed him. This is a critical time for him to be with his parents and siblings for his own sake. He is a wild bird and the less time he spends being 'observed' in captivity, the better his chances of survival.

I also got the bad news from Mark that Alba, the missing female, had a collision with one of the buildings and died as a result of her injuries. She will be missed. On a high note however, without the help of the CPF volunteers, the property managers, security personnel, and other concerned citizens, we could easily see a mortality rate of 90 percent. We still have the 2 other females and Ox.

On arrival at MEC I saw the adult male perched on MEC 1 a few sections to the left of the nest box. Neither of the juveniles were in sight. As I walked up the path between MEC 1 and MEC 3, the male flew out overhead and started kekking the alarm call. I looked around all over the horizon but no other birds were flying in the area. I put my binos on him once he'd landed, and followed his gaze to behind where I was standing. There, walking along the path under the cover of trees were two men, each walking their dogs. They stopped and chatted to me. It turns out the adults, more likely the male, HATE a particular big black Lab! No other dogs seem to bother him, just this particular dog. I explained to the dog's owner that it was nothing personal, that the young birds were fledging and it is probable this male had a bad encounter with a black Lab somewhere else and now is only being protective of his kids. The dog's owner was concerned for the safety of his pet. I advised them to stick to the trees when they walk their dogs. The two young females appeared to see what all the fuss was about, and the male continued to yell in protest and circled overhead a few times. It is unusual for peregrines to be that bothered by anything on the ground. They typically tend to defend against arial threats, although all evening various gulls were allowed safe passage as they flew by.

Around 8:15pm I saw the male take off in a definite hunting flight. I have seen both adults initiate these hunting flights but I always miss when they make the kill. So I ran after him and rounded the corner of MEC 2 to see the female ring up with something in her talons. It appeared as if the male took off to aid the female in the chase and the result was dinner for the girls. Mom flew to the nest building and spoon-fed one of the girls. The other one was very sleepy and made her way back to the nest box area. I left at 9:30 after watching the juveniles crawl into the nest box for the night.

Guylaine Drolet reports:
2 PM - Upon arrival at MEC, I immediately saw one of the juveniles "J1" perched mid way on MEC #2 facing NW. Both parents were near by. Dad was roosting to the left side of the nest box and mom was perched on the NE corner of MEC #2 I quickly scanned all the buildings. No sign of the other juveniles at this time.

Since Ox's off at Guelph University, I've got one thing on my mind, find the other 2 babies.

2:30 PM - The MEC #2 juvenile takes flight, circling around a couple of times between all four buildings. Kacking all the way. Both parents joined her. All 3 birds were flying above MEC #3. The parents were soaring a couple of times. I lost sight of them and then it got really quiet. I decided to walk around MEC #3 and scan the roof top ledge but didn't see any bird perched.

Making my way back to the MEC #3 water fountains, I discovered "J2". She was perched on MEC #1, same level ledge as the nest box, near the NW corner. One of the parents was now at the nest box. No sign of juvenile "J1" at this time.

3 PM - Mom flew in and out of the ledge were "J2" was perched and then mom flew back to her regular spot NE corner of MEC #1 in plain view of "J2" and the nest box. "J2" started making her way back towards mom but she didn't jump over the gap instead, she started doing a lot of flapping - walking back and forth on that same ledge. Dad was still at his same spot near the nest box.

3:15 PM - "J2" made her way to the NW corner edge of MEC #1. Flapping her wings for a bit, then she settled down and took a little break.

4 PM - Spotted "J1" perched on the N corner of MEC #2. At that time, I decided to take a walk around MEC #2 and MEC #4 to try and locate "J3".

4:15 PM - No sign of "J3" anywhere. And at this time, I don't have a visual of "J1" anymore. Both parents are calm and still perched at the same locations.

4:45 PM - "J2" took off from the MEC #1 NW corner and flew quite nicely back to the nest ledge. She kept her altitude very well and seemed to know exactly where she wanted to go. Her landing was pretty good.

5 PM - Mom took flight, circling over MEC #2 a couple of times, she was trying to encourage "J1" to take flight. Dad also took flight and also circled the MEC #2 building but he landed at the center of MEC #2 facing NW, right above the window ledge. "J1" on the roof top ledge, started flapping her wings running towards her dad. "J2" was kacking and flapping her wings, she must have gone to the roof top, I lost sight of her. Mom flew back to her regular spot on the NE corner of MEC #1.

5:15 PM - Dad flew back to MEC #1 same level as the nest ledge near the SE end of the building. Decided to take a walk around MEC #1 grounds to try and locate "J3". Looked everywhere for her. No sign of her yet.

6 PM - Both parents have taken flight, my guess is that they may have gone hunting. "J2"'s on top of the nest box, haven't seen "J1" since 5 PM.

6:20 - Both adults are back. Dad stayed put to the south of the nest ledge, mom took off again.

6:30 - Mom's back, perched on top of MEC #2 near the NW corner. She's prepping food.

6:40 - Mom carried the small game back to the nest ledge. To my surprise, J1" and "J2" got up from the top of the nest box. "J1" must have made it back to the nest box when I took a walk around the grounds. Both girls Kacking loudly, one of them immediately managed to grab her dinner from her mother's grip. The other one, stayed on top of the nest box. A couple of minutes later, she tried to steal some food away from her sister but didn't succeed. Both parents flew off again.

7 PM - Both parents doing "fly-by's". Saw mom go around the corner of MEC #2, I'm pretty sure that she was carrying another juicy meal. Yes indeed, about 5 minutes later, mom returned to the nest ledge to feed the other baby With all this commotion, all the kacking, finally I got a visual on "J3". She must have been on the roof top on MEC #1 all day. She was now on the roof top ledge, slowly making her way right above her 2 sisters.

She would look down at her sisters and they would look up at her. I really thought that "J3" would try to fly back to the nest ledge but she didn't.

8 PM - Visual of "J1", "J2" and "J3" all still at MEC #1 including both adults. "J3" still not fed at this time. I never saw "J3" take flight but she was on the roof top of MEC #1

Maya Basdeo reports:
5pm - 9pm
On arrival there was still no sign of Ox. The nest ledge only had two of the juvenile females. I did continual rounds throughout the area looking high and low. The good news is that no peregrine remains were found. I was hoping against hope that the two missing birds were okay. All evening at least one, if not both adults were in view keeping an eye on the chicks still in the nest ledge. The adults were taking turns flying around the property but were not sticking to any area in particular. Towards 9pm food was delivered to the nest for the two juveniles. It was getting dark so I headed home. Later on that night I received a call from Mark Nash. One of the birds had been spotted behind MEC 2 on the ground. I raced back to MEC and drove around back. Sure enough there was a young peregrine sitting on the rim of a flower planter. I got out of the car and slowly angled towards it. It was apparent from his size that it was Ox. I noticed even from a distance that his beak was open, and I wondered if it was stress. Ox and I played a short game of tag before I was able to scoop him up. He made not a sound, and seeing him at close range I saw that his lower mandible (jaw) was quite crooked, and he was unable to close his jaw. I checked inside his mouth and it looked normal, other than some dried blood near the opening of his beak. It looked and felt to me like his jaw was either broken, or dislocated, or possibly both. The next morning Ox was taken to OVC at Guelph by OMNR biologist Mark Heaton. The initial prognosis was that the bird had frounce - which I found odd because there was no swelling and there were no open sores inside Ox's mouth. Blood work and X-Rays were scheduled to determine the actual condition.

7:30pm - 8:45pm
I arrived to find 3 chicks visible on the nest ledge. They were sitting close enough together for me to see they were all females. I watched them for a while and noted one of the adults was perched on the west corner of MEC 4. None of the girls did any amount of flapping. They seemed content to shuffle in and out of the box, perch on the porch and preen. I decided to take a walk around since this is the second day that only 3 at a time were visible. I started to walk up the drive to MEC 2, looking at the lower level flower pots, and then up a little higher to the lower roof level. Lo and behold...there was Ox! The little guy had obviously fledged at some point since Thursday. I checked the very same area yesterday and he was not visible. Tonight as I walked towards him I stopped about 50 feet away and looked at him through my binos. He was sitting on a lower roof with his eyes closed. I made a little noise and he opened them and looked at me. He had his feathers floofed out and didn't seem to be in a hurry to go anywhere. He sat there for several minutes and when I felt comfortable he wouldn't try and take off across the road I ran to call the Oxford Property Security. I picked up the rescue box and towel, just in case. Ox however, decided he didn't want to fly again tonight. He spent some time walking the ledge, stretched a few times and even pooped. His mute was starting to get a tinge of yellow but nothing overly alarming yet. I periodically looked up to the adult, who was watching my movements very intently. A few minutes before I left, Ox had dropped down out of view, and the adult plunged off of MEC 4 travelling straight downwards in a hunting stoop. I wish I had seen the outcome. I will return tomorrow morning where I hope I will find Ox bright-eyed and bushy-tailed ready to take flight and gain some altitude. There is hope for him - as he walked along the ledge tonight he didn't trip over himself once!

10:00am - 11:30am
I arrived in time to see mom swoop onto the porch with food. She was carrying a bird that was black and smaller than a pigeon. I am going to guess it was a grackle or a blackbird of sorts. I saw two chicks in view initially and the adult female seemed to be dishing out portions directly to the chicks. It was cloudy, a little on the cool side and very windy. By around 10:15 the female was off the ledge and both her and the adult male started soaring around MEC 1, climbing in altitude the whole time. 3 chicks at a time were now visible and they seemed to be preoccupied with jumping up and down from the upper and lower ledge beside the nest box. The adults started soaring and circling, moving westward until they were eventually out of sight. I was a bit worried at only seeing 3 eyases, but the parents were not behaving in an agitated manner. Five minutes later the female returned and landed on the south corner of MEC 1. A few minutes after she returned, dad appeared out of the west and started making circles between MEC 1 and MEC 3. He started sounding the alarm call at something beneath him but I couldn't see what it might have been. The female took off as well and they both spent several minutes circling the green area between buildings and then making wide circling flights between MEC 3 and the CIBC building on the NW corner of Highway 10 and Robert Speck Parkway. The male seemed to disappear on the west side of the CIBC building and the female returned to her post on the south corner of MEC 1, looking westward. Since all was quiet at the nest I decided to do a walk around the area to see if anything was amiss. I checked the immediate area around MEC 1 and walked over to check around the CIBC building and parking lot. I looked in all the trees, bushes, ledges...but didn't see or hear any traces of a juvenile peregrine. Mind you, in the middle of the day with lots of traffic and construction going on it would have been hard to hear a faint scream. I checked all the roads and driveways as well. I walked back and went around MEC 2, still nothing. I went back to my own perch on the bridge opposite the nest and the juveniles were up again. The parents took to the air again and swirled around eachother in the sky over MEC 1. The then both flew to MEC 3 and landed just a few feet apart. They sat there for a few minutes and then flew back to the nest building, MEC 1, where the female took to her post at the south corner of the building and the male was perched half way between her and the kids at the nest.

I did not see all 4 juveniles at the same time while I was there. If there is one missing I hope it is okay. The parents were flying quite a bit, but not in a way that they tried to encourage the young off the ledge. Very little flapping was done by the juveniles while I was there.

4:45pm - 6:15pm
I arrived on site to find only 2 juveniles on the nest ledge. One was on the front porch, the other one was beside the nest box. I couldn't see the adults either so I decided to take a walk around the buildings to see if I noticed anything out of sorts. I walked to the corner of Robert Speck Parkway and Highway 10, and was heading south on Hwy 10 when I looked up in time to see an adult peregrine fly directly above me, carrying a very juicy looking black and white pigeon in it's grip. The adult headed in the direction of MEC 4 so I turned around and ran to see where it went. By the time I got back around the corner and opposite the nest site, the adult had perched on the north corner of MEC 4. I turned my binos to the nest and saw 4 juvenile peregrines all in a row. Within moments the other adult appeared and soared to south area of MEC 2. I watched the juveniles for a while. They seemed to be mostly preoccupied with jumping down to the lower ledge that runs beneath the nest box. Only one of the birds, the male Ox, did any amount of flapping. I could tell it was him because he looks 'mini' in comparison to his sisters. He started to flap a little and walk along the nest ledge. He hopped up on the porch and was bobbing his head as he eyed the roof of the box. With a great deal of flapping he jumped up onto the roof of the nest box and immediately looked very pleased with himself. Finally he was looking down on his sisters, rather than the other way around! The three girls seemed to stick close together, even in play. At about 5:20pm one of the adults took off towards the nest ledge with food. The other adult saw this and also took off for home base. The chicks saw this and all got very excited. They began flapping and screaming in their famous food-begging manner. The male landed with the pigeon and the female landed a moment later. He presented her with the prize and she promptly grabbed the kill and flew out to MEC 2 where she began the task of defeathering and quartering dinner. The chicks looked a little shocked, even speechless, as if they were asking themselves if food really did come in and then go out, or if they had just imagined the whole thing.

Once mother had peeled and plucked to her satisfaction, she flew back to the nest and deposited the food directly into the nest box. All three girls screamed and gobbled. I could see one of their tail feathers sticking out of the opening, but that's it. Ox remained on the roof of the nest box and peered down at them. The girls continued to eat and Ox stared out at the world that lay beneath his talons. He started to flap more regularly and made a huge step in flapping from the roof of the box to the edge of the window section that holds their family home. Dad was perched on the south corner of MEC 1 and Mom had flown to MEC 3 to watch her kids from a distance. Ox flapped back and forth along his portion of the ledge and then finally half jumped, half flew over the small gap between glass sections. He landed (barely) on the next section of ledge. I hope when it comes time for him to fledge that he flies better than he runs, as he is constantly tripping over his own feet.

When mom saw this she promptly swooped into the box, grabbed the remaining tidbit of food from the girls and dropped it off for Ox. The food must have fallen to the lower ledge because Ox couldn't jump down below fast enough. Mom sat on the ledge while the 3 girls stood on the porch of the box, all heads turned in the direction of where the food went. Dad took off and landed on the roof of the building while Ox jumped back onto the visible ledge beside his mom. It was a beautiful family portrait of all 6 birds.

It didn't last long though. Ox started to run towards his mother in begging posture so she took off and landed on the east corner of MEC 1. Dad circled around and then headed south out of sight, and the 3 sisters remained close to the nest. Dark clouds were starting to roll in and thunder shook the sky. Ox was focused on preening and during the time I was there, neither of the parents were doing fly-bys trying to coax the young off the ledge. I also noticed that Ox, although he will likely be the first to go, still had down visible on either side of the base of his tail. Tomorrow is another day.

Guylaine Drolet reports: 2:15 PM to 2:45 PM
Quick check on the babies. Upon arrival, we saw all 4 little ones safe on the nest ledge. The parents did do a few "fly by's" to encourage them to take their first flights. We did see a lot of wing flapping. But for the most part, the babies stayed put.

One of the adults was keeping watch perched on MEC #1 at the same level as the nest box, just a few ledges away.

Tuesday June 14, 2005
Guylaine Drolet reports:
Upon arrival I was able to see 3 of the chicks. 2 were up, sitting on the left side of the nest box. Preening, alert and the other one I could see was taking a snooze in the back right corner of the nest ledge. I'm pretty sure that the one resting was OX. When he woke-up, he preened for a bit and then he started flapping his wings. On several occasions, he would start flapping his wings and start running from the nest box along the edge of the ledge, running all the way to the gap between ledges.

One of the parents was perched on MEC #1 @ at the same level as the nest box all the way to the last set of windows near the SW corner. The other adult brought some food to the nest ledge at 4 PM. I did see it take 3 or 4 little bites but I didn't see any of the babies rushing towards it... One might have been in that corner and I just didn't see it. This adult then flew to the NW corner of MEC #1 perched at the same level of the nest ledge and stayed put to keep watch.

2 of the babies, (one of then being OX) were doing a lot of flapping. I was never able to see all four babies at one time. And considering that the girls are all pretty much the same size, it's very difficult to tell who's who?

Both parents stayed perched at each end of MEC #1 pretty much the entire time I was there. I stayed for several hours. Just before I decided to leave, I did manage to see 3 of the babies.

Webmaster's note:
Although it had to be rescheduled for Monday, the 6th of June, the banding ceremony went very well. We are happy to report that the three 900g females and the one 660g male were successfully banded and are in excellent condition. The adults were very territorial and protective (both of which are good things for the peregrines), as evidenced by some of the pictures.

Friday May 27, 2005
Webmaster's note:
The date and location of the banding of the chicks has been confirmed. The four young ones at the MEC will be banded on June the 3rd in the lobby of the MEC building at 1 Robert Speck Parkway. The ceremony will take place at 3 pm., and, we are happy to say, will be open to the public! Please feel encouraged to come out to see the chicks and the banding process.

All is well with our happy little family. As I turned the monitor on, mommy was in the process of cleaning house. So I got a plain view of the 4 adorable little fluff balls.

I saw 3 of them (the bigger ones) casually waking up, preening, yawning. The 4th little one did move a couple of times but for the most part was snoozing away.

We have babies...
Upon arrival, I did see on of the adults perched on MEC #4. Turned on the monitor, the other adult was incubating... I got lucky, again, as the adult got up to do a bit of housekeeping. There's at least 3 babies for sure. It's very difficult to distinguish the little fluff balls all cuddled up together. Didn't see the last egg, then again, there's a very good chance that they've all hatched.
In my opinion, the first hatch must have happened on Friday May 6th, sometime after my quick check.

Guylaine Drolet reports:
2 PM
Upon arrival, I observed the 2 adults perched on top of MEC #4 NW corner. I ran inside to try to get to the monitor before the female would return to incubate her eggs.

Sadly for me, she made it back to the nest site about 30 seconds before I turned the monitor on. I thought for sure that I'd have to sit for a while, but within a couple of minutes, she got up to re-arrange her eggs.

I'm happy to report that all looks well with all 4 eggs!!!

2:45 PM - MEC nest site, confirmation: We have 4 eggs!!!

Upon our arrival, the female was resting, incubating her eggs. 15 minutes later, she slightly got up and proceeded to turn her eggs. At that time, we were only able to see 2 eggs. About ten minutes later, she got a visit from the male. She got up and left the nest. That's when Wendy and I clearly counted 4 eggs!!! The male immediately got comfortable and took over the female's duties.

As we were leaving, we saw the female perched on MEC 4 preening her feathers

Mark Nash reports:
Today I attended the MEC nest site location to get a handle on the current peregrine activity at the nest box, and it would appear that my visit was just in time.

Spring has sprung indeed, and the peregrines are well ahead of schedule at most of the southern Ontario nest sites being monitored. The Mississauga MEC nest site is no exception.

As always, the staff at the MEC centre was kind enough to all me access to view the small TV monitor that is hooked up to the nest box camera, and I observed both territorial adults on site, and in fact, the female was observed laying down in the nest box incubating egg(s)??. Sadly, I was not able stay long enough today to "out wait" the female's incubating an undisclosed amount of eggs.

Stay tuned, as I will be visiting far more often to try and get a better handle on the situation.

Bruce Massey reports:
I found 2 birds, male and female in attendance around 0900 hrs.

Wednesday August 25, 2004
Guylaine Drolet reports:
3 PM to 6 PM - Observations at MEC upon arrival. No birds in sight. As I then decided to make my way towards MEC2, I started hearing screaming... I looked above and saw Mom soaring very high up, a few seconds later, the screams got louder and louder, Pat and Sunny suddenly showed up, flying together from beyond MEC1, yes, screaming their little heads off, flapping their new found wings very fast, how could anyone not notice their presence? They were flying East, playing... What a great thing to see.

Both then took a bit of a breather, Sunny perched on the N corner of MEC2 and Pat back near the nest ledge. Around 3:40 PM, Sunny got fed, I believe it was dad with her. Pat stayed put. Sunny then took a little nap satisfied from her snack.

There was a lot of activity from both babies. They would both take off, fly around and be out of my sight for a bit, then eventually come back in view.

Around 5 PM, I saw Pat fly in from behind MEC2, he came to the nest ledge with a small package in his talons. The commotion woke Sunny up and she couldn't resist but to try and steal his meal. She missed. Both babies took off and I didn't see them for a good 15 minutes. They both made their way back to the nest ledge and took a well deserved nap.

At 6 PM, They were both safe and sound, preening by their nest box.

Thursday August 19, 2004
Maria Pezzente reports:
6.05-10am: At 6.40 this morning Dad brought food for Sunny up onto the roof. Pat decided to try to get some of the snack as well so he quickly flew up from the ledge onto the roof. Another feeding took place, courtesy of Dad, later this morning around 9.30 am and again Sunny managed to get most of the food.

Earlier in the morning I saw two other falcons (possibly Merlins) flying in the area. They made their way over to building # 1 and one even landed on the west roof corner with Dad being on the ledge right underneath. The falcon took off within a matter of moments, but all of this took place without any objection whatsoever from either parent.

Pat showed off his flying quite a bit today. He flew around MEC building #1 several times and made longer flights that lasted up to 30 seconds!

Wednesday August 18, 2004
Maria Pezzente reports:
6.05-9.35am: Upon my arrival Pat was sitting on top of the nest box. Dad landed on the west corner ledge of the building and Pat ran over to him. As Dad didn't have any food he instantly took off for the east side of the building, and was immediately followed by Pat. After this manoeuvre Dad flew again to the west side of the building and landed on the roof. It only took Pat a few minutes to decide to fly up onto the roof as well. Dad took off, but Pat remained on the roof and ran on all sides of the building for a large part of the morning. Pat was flying from the roof for little 5 second flights and probably had completed 10 of these flights before I left. He also flew to building #3 where Dad was situated at one time, and made his way back again after a few minutes. He looked great! Sunny was spotted sitting on the roof on the north side building #1 where she remained for most of the morning. I didn't see any food being delivered to either her or Pat today.

Guylaine Drolet reports: 5 PM to 7:45 PM. - 5 PM - Mom rousting on top of the nest box, Pat over 3 sets of windows S.
6:10 PM - Pat flew to MEC #3 and back to MEC #1.
6:20 PM - Mom flies to around and returns to MEC #1 roof top NW corner.
6:30 PM - Pat's on roof top of MEC #1 E corner. Mom takes off and lands on the SE corner of MEC #2, takes off again to NE corner of MEC #4.
7:10 PM - Mom perched on the E corner of MEC #1, Pat on the nest ledge made his was to the same corner, screaming his little beak off the whole way.
7:20 PM - looks like dad just brought in an evening snack to Pat.
7:30 PM - Poring rain, Pat's back on the nest box. Mom perched on the N corner of MEC #1.
7:45 PM - Still pouring, decided to pack up and go.

Tuesday August 17, 2004
Maria Pezzente reports:
6.10-10am.: - Upon my arrival Pat was already nibbling away at a little piece of food. Dad did briefly land on the ledge around 6.40 am, but didn't seem to have brought anything with him. Dad came back again within a minute or so, but again I saw nothing to suggest food had been brought in and he quickly flew away.

Mom made a food delivery, a freshly killed dove, to Pat around 7.30 am and remained on the ledge for no more than five minutes. After this Mom flew with the food up and around the building, presumably onto the roof to feed Sunny, but I couldn't confirm this from the angle where I was sitting. Sunny was not seen all morning. Pat enjoyed nice long naps and was hardly active at all.

Guylaine Drolet reports: 5 pm to 8 pm: Mom fed Sunny on the roof top around 4 PM. About 20 minutes later, mom flew over to MEC #3 with some food left in her grip. A few moments later, Lenore saw 2 adult males fly in between MEC #1 and MEC #3. The 2 babies were in view, Sunny on the roof top and Pat on the nest ledge. These 2 adults actually locked talons and did an amazing display in the air. That only lasted a few seconds and the two flew south.
4:45 PM, mom fed Pat on the nest ledge.
5 PM, mom's perched on MEC #3 SW corner. Ten minutes later, she flew away. Mom & Dad flew together and both landed on MEC #2. Dad shortly after took off. Sunny started walking towards the S corner of MEC #1. Lenore and I relocated to MEC #2 to keep on eye on her. She stayed put for a good 45 minutes. Mom then relocated to the NE corner to MEC #1. Of course, Sunny started making her way back towards mom.
6:45 PM, mom flies around MEC #1 and lands on the left ledge next to the nest box. Sunny's still on the NE corner. Mom then takes off and eventually settle's on the NW corner of MEC #2.
7:20 PM, mom flew from MEC #2 to MEC #3 South mid way, right above us (sitting near the fountain).
8 PM, Pat settling near the nest box, Sunny is perched on the N corner of MEC #1 and Mom was still rousting on MEC #3.

Monday August 16, 2004
Guylaine Drolet reports:
5 PM to 8 PM - On my way in, at Dixie and Rathburn I spotted an adult peregrine being chased by a flock of small birds. I believed it was mom, she was flying west towards the MEC buildings.
5 PM - Pat rousting on the SW corner of MEC #4. Dad was rousting on the nest box.
6 PM - Mom rousting on the SW corner of MEC #4 per Bruce. Unidentified male perched at 55 Civic Park Circle. N window, 2nd row NW. Same time, dad chased away the impostor. To our surprise, 15 minutes later, we spotted both males perched on the same building #55 at Civic Park Circle. Quite peaceful, minding their own business. No sign of Sunny, at this time, it's assumed that she's still on the roof top of MEC #1.
6:30 PM, that's when Pat started making his way to the N Corner of MEC #4. Jumping over the 5 gaps. Ten minutes later, he took flight towards MEC #3 and landed on the SW corner. Vocalizing... Mom took off, heading East. A few minutes later, Pat flew over to MEC #1, E in the middle section of the roof top. 3 times, he tried to fly to the nest ledge, only to fly beyond it and land on the N side of the building. Eventually, he ran to the NE corner, his little behind, going left/right, left/right... From the corner, he flapped his wings and at a 40 degree angle finally made it to the nest ledge. Safe and sound at last. Mom was perched on the NW corner of MEC #3. No food was brought to Pat while Bruce & I were there. Mark took over the watch around 8 PM.

Sunday August 15, 2004
Maria Pezzente reports:
6.10 - 11 am.: - Upon my arrival Pat could clearly be seen sitting on top of the nest box, but Sunny was no where to be found all morning. At 6.40 am Dad made a quick food delivery to Pat and was soon after sitting on top of building #1. I tried to locate Mom by walking around at all of the MEC buildings, but she wasn't spotted until 9 am when she brought an impressive chunk of meat to Pat, feeding him for nearly 20 minutes.

Pat has clearly gotten some of his confidence back and was running around flapping his wings for a large part of the morning, venturing further away from the nest box. He made quite a jump from the top of the nest box to the very corner of the ledge, then jumped effortlessly over the gap to the corner of the building. Today he also jumped repeatedly over two new gaps from the east corner of the building north.

At 10.45 am two hawks showed up on the scene and Mom and Dad were busy sounding the alarm. Dad followed this up with vigilantly trying to chase the two hawks away.

Saturday August 14, 2004
Maria Pezzente reports:
6.10 - 11.10 am: - The chicks were quite vocal early in the morning, so food was definitely on their mind. Dad finally made a quick drop off of food at 6.40 am and Pat grabbed it, leaving just about nothing for Sunny who continued to vocalize. At 8.30 am Mom arrived with a large delivery and fed both chicks, but mostly Sunny, little piece by little piece for approximately 20 minutes. After this feeding session Mom flew to the west corner of building #3 and made loud calls for quite a few minutes. This was followed up by her flying a little lap in front of and almost around building #1. Both chicks soon responded to this with a little flapping even though they must have been very full, but soon settled in for a long nap.

Pat did jump over the gap and on to the next ledge again later this morning. He was napping quite a while at the east corner of the building and investigated the East-North side but without jumping over next gap. For this reason most of the watch was conducted from building #3, which has the fountain in front of it, as it was impossibly to see him from any other angle.

Michael Fazackerley reports: Evening shift - 10:35 - 22:35: - The calm scene of dozing juveniles and attendant parents on nearby ledges I arrived to the morning belied the coming events of the day. Little of note occurred up until Dad bringing food at 3:30pm which, in itself, has become somewhat routine. At 4:30, however, Sunny launched herself suddenly from the nest ledge and proceeded toward MEC2 joined by Dad. Unable to gain the altitude to reach a safe perch on MEC2 Sunny turned SW and eventually set down on 33 Hurontario just across the street as Bruce pursued them to monitor the situation. Despite the uproar Mom paid a visit to Pat and fed him in the attentive manner she had fed Sunny earlier in the day.

As I monitored Mom and Pat, Dad had returned to perch on MEC2 and a third bird flew past the building heading North I had thought to be Sunny. The 3 went into an aerial display of their flying prowess North of the MEC buildings and then returned heading Southwest. Mom and Dad alighted on MEC1 but Dad shortly headed off in pursuit. We would later learn from Bruce that an unknown adult peregrine had stooped at and harassed Sunny at 33 Hurontario. In the commotion we lost Sunny only to have her later fall almost right into our hands. As Tracy returned from joining Mark and Bruce the other side of Hurontario Sunny glided in from the West directly beside where I was watching from the Scotiabank parking lot at MEC2. There were some slight logistical challenges to Sunny's rescue but after her recovery she was found to be healthy and vigorous to say the least. The rather large perturbed juvenile was carefully returned to the MEC1 rooftop none the worse for wear.

Friday August 13, 2004
Guylaine Drolet reports:
2:15 PM to 8:45 PM. - Upon arrival, visual of both juveniles on the nest ledge. Pat was on the R ledge next to the nest box. Sunny was napping left of the nest box. Mom perched right above me on MEC #3 S.

Mom stayed put for quite a while. Around 3 PM Pat made his way back to the nest ledge. A little hop, no problem. For the next couple of hours both juveniles were just taking it easy.

Around 5 PM, saw mom and dad fly by together and land on MEC #2 NW corner. Shortly after, mom came right to the nest box. I though that she might be bringing in dinner but she immediately flew away. Didn't leave anything for the babies to eat!!!

5:15 PM to 5:30 PM, Daddy landed right on the NE corner of MEC #1, where the babies could see him. Pat ran over, hoped over to the next set of windows and started flapping his wings calling out a daddy. He was getting very excited running back and forth, flapping away. A coupe of times, he was sitting right on edge of the corner... Very exciting indeed. While this was going on, Sunny started to flap away and wanted so much to join her brother to the other ledge, she almost did a few times but remained on the nest ledge. Flapping session, I was crossing my fingers they weren't going to take off at the same time. Daddy took off and the babies calmed down.

Mom came back, she's never gone for too long. Perched on the N corner of MEC #4 at first, then flew over to MEC #3 S corner. Rousting...

At one point, Pat did fly to the top on the nest box.

8:45 PM both babies on the nest ledge, starting to settle in for the night.

Thursday August 12, 2004
Maria Pezzente reports:
6.15-11.30 am. - The two chicks were sleeping for a large part of the morning. When awake, Sunny was the more active of the two, flapping away quite a bit. Pat did jump from one ledge to the another over the little gap and he was happily sitting on the corner ledge until Mom came in with a meal. That of course prompted Pat to run as fast as he could back to the nest box! Relieved by Michael how is on site for the afternoon shift.

Guylaine Drolet reports: 2 PM - Both juveniles on the ledge. Pat rousting, Sunny napping flat on her belly. Mom was perched near the NW corner of MEC #2. Around 2:45 PM, she took off. Not much to report, babies up and preening around 2:30 PM.
3:30 PM "Snack time" brought by mom, dad did join the happy family on the ledge but only for a very brief moment. Pat immediately grabbed his snack. Sunny was aware of something going on but because she was sitting on the left side of the nest box, didn't realize that a meal had been brought in. About five minutes later, she made her way over to Pat and managed to get her share. After they were done, a well deserved nap was taken.
Both adults stayed in view the entire time. Mom perched on the NE corner of MEC #2 and Dad on MEC #1, 4 window rows to the left of the nest box. Dad took off later on.

When the babies woke up, a major preening session took place. Around 5:30 PM Sunny became more active and started flapping her wings. That lasted about 5 minutes, Pat was also flapping a bit looking up on top of the nest box.

6:30 PM, both babies rousting on the nest ledge. Tracy Simpson reports: 7:00PM to dusk - It would seem as though little Pat's experiment with flight the other day has had him "eating humble pie" since his return to the nest ledge. The two juveniles spent the entire evening as "bookends" sitting side by side watching the world go by. The adults feeding schedule is definitely slowing down as no evening snack was brought in by either parent. Mom did visit the pair on the ledge around 8:45 and may have dropped something off but if so, it was incredibly small. Hopefully we will have more adventurous and hungry chicks come morning.

Wednesday August 11, 2004
Maria Pezzente reports:
Remo and I arrived at the MEC site at 6.50 am and instantly saw some activity around the nest ledge. The adults flew back and forth twice, but settled down shortly after. What we didn't realize is that little Pat had already taken his first flight and was by now located on the ground, close to building #1. Well, within 25 minutes of our arrival suddenly we saw two peregrines fly very low toward the building #2 on the south-east corner and the fledgling looked as though he would have smacked right into the building if it wasn't for Mom flying between him and the window making him wear off in the very last moment.

We weren't able to see the little guy for a few minutes until he reappeared and flew across Robert Speck Parkway, again quite low to the ground, and unfortunately right into building #3. Luckily he wasn't flying at great speed and did start to lift up at the last moment, so he likely had just a "belly impact". He did fall to the ground, about 2 storeys or so, where we were quickly able to scoop him up and whisk him away for observation. Mark Nash was called in to examine Pat for potential injuries. The two adults remained at their posts being quite vocal for the next 1 1/2 hours. Eventually they did move and "Dad" was seen flying off for a hunt later in the day.

Sunny mostly rested and slept on the ledge up until the time we left around noon, only with the occasional little wing flap. We did observe Mom come in with food and to our great surprise she appeared to be tearing it and feeding Sunny!

Mark Nash reports: Afternoon watch - Arrived ton site around 12:30 pm to check out and examine little Pat, who had come into contact with one of the MEC buildings on Maria's watch while on his first flights. After a detailed examination, and held for a period of time to ensure that his impact was just a minor one without any ever lasting effects, little Pat was finally released back to the roof top of MEC #1. He quickly voiced his opinion of the ordeal, and scurried over to the retaining wall ledge on the roof. He was later observed atop of the ledge (on the roof elevation) and for the next 8 hours, ran around the entire ledge of the roof top ledge, following his parents as they flew around the building throughout the day. As of 8pm, Pat was still screaming to his parents on their fly by's of the nest building. 

Tracy Simpson reports: 7:30PM to dusk - When pulling up to MEC I was able to see little "Pat" on the northwest corner of the roof looking rather humbled after his earlier rescue and release. I met Mark and Michael, our newest educator at the foundation, in the parking lot of MEC 2 only to see mom and dad pull up to the nest tray with a food package for Sunny shortly after 8:00PM. While Sunny happy filled her crop her brother could stand it no longer and made his way around the ledge to the east side above the nest box ledge. Twenty minutes of pacing and he finally got up the nerve and jumped...kited in the wind...and...MADE IT TO THE NEST LEDGE where he happily tucked in for the night snuggled up to Sunny. Glad to see him home.

Tracy Simpson reports:
6:30PM to dusk - Upon arrival I couldn't find either of the juveniles on the nest ledge. I set about checking the camera and all the ledges around MEC 1 as well as all of the places a bird might come down to. When I came back around to look at the ledge, the two little "book ends" were sitting side by side with matching messy faces and crop bulges. Dinner had arrived just before I had arrived. Sunny thereafter spent her time, you guessed it, sleeping off dinner. Pat, on the other hand, had found a new world to play in; the top of the nest box!! He was regularly going up to the top of it with confidence and strength and gnawing on the ropes that are holding it in place. I guess he's decided that the only way to get off the nest ledge is to chew his way off!! By dusk they were both on the edge of the nest tray sleeping soundly.

Monday August 9, 2004
Tracy Simpson reports:
7:00PM to dusk - This evening only Pat was visible for a good portion of the time. Investigations from an office at the top of MEC 4 and a look at the camera was of no help. It turns out Sunny was tucked away participating in her favourite activity; napping! Pat was, in contrast, playing all over the nest ledge with anything that would play with him. Zipping back and forth across the ledge with lightning speed, he attacked all that came in his path. This active little boy has quite a "sense of humour" and we look forward to seeing him take his first flight!!

Sunday August 8, 2004
Tracy Simpson reports:
6:30PM to dusk - Both Sunny and Pat were visible on the nest ledge tonight. Pat has already made forays from the nest box to the ledge and back several times. He looks quite well co-ordinated and is gaining strength and confidence daily. His current obsession is to get on top of the nest box. He made several attempts that, once failed, led him to pounce instead on his sister. Aren't brothers swell? Sunny seems to spend most of her time screaming at inanimate objects, trying to rub off the down "mohawk" on her head or sleeping. Flight is definitely NOT on her immediate list of things to do!!

All the best to the little ones!!

Mark Nash reports:
Banding Day - A great day indeed! With the tables set up in the lobby of MEC #1, MNR at the banding helm, CPF volunteers in position, a full lobby of spectators, and all ready to go, Emma Fellows, a biologist with the MNR proceeded to the roof with Skyreach team to access to descend down to the nest ledge and the nest box to capture up the 2 chicks to bring them back to the lobby for banding.

At approx. 10:45 am, the two chicks arrived at the lobby, where Mark Heaton and Pud Hunter, biologists with the MNR proceeded to weigh and band the two very healthy peregrine chicks. The two chicks, (one male and one female), were of very good spirits, weighed in at 941 grams for the female, and 656 grams for the male, were banded without a hitch. As usual, the window washers swing stage along with MNR biologist and Skyreach staff remained in position to distract the adult peregrines while the young peregrine chicks were absent while being banded.

Much to the delight of a full lobby of spectators, the two peregrine chicks were banded, sexed, and named in good time. The two chicks were named by the Oxford management team, with the young male being named "PAT" , and "SUNNY" for the young female. The two peregrine chicks were returned to the nest ledge in good time, while the adults parents voiced their concerns and kept the capture team on the window washers swing stage busy.

Many thanks to all, including all of the CPF volunteers on hand, (Bruce, Maria, Bruce, Tracy, Marion, Guylaine, and Lenore). Many thanks for all the incredible support of the management team of Oxford Properties - (Danielle and Santos), and the MEC security and maintenance staff, as without their support, the day would not have gone so well. A big thank you to Skyreach for their support with both staff and swing stage to get us to the nest ledge to capture up the chicks for the banding.

Our thanks to Ziggy for the photos taken from the roof top of MEC 3, capturing Skyreach and Emma as they accessed the nest box to capture up the chicks.

Monday July 12, 2004
Mark Nash reports:
It has been confirmed that the chicks will be banded in the lobby of the MEC 1 on Wednesday July 28th at 10:30 am. You are all invited to attend the banding of the peregrine chicks.

The MEC is located in Mississauga, at # 1 Robert Speck Parkway (Hurontario Street and Hwy # 403), directly across from the Square One Shopping Centre Mall

Guylaine Drolet reports:
2:30 PM, went to MEC to check up on the little ones. When I arrived, just as I turned on the monitor, the little one's were snuggled together and mommy took off. A couple of minutes later, she returned with their mid afternoon snack. What a treat. I manage to snap quite a few pictures. Watched them enjoy their meal. When they were all done, mama just wrapped her self around her babies and that's when I decided to leave.

Tried to locate daddy's whereabouts but no luck. By that time, it was starting to rain. Better luck next time.

Mark Nash reports:
Tracy has reported that we have finally have a hatch at the Mississauga nest site, with both eggs having hatched as of June 29th. Congratulations again MEC!!

Due to all of the territorial battles at the MEC site, we have no idea who the victors are, and as such, have no idea as to which pair of birds are actually occupying the net box. Time will tell, as we are watching the site as closely as we can to identify the band numbers of the adults on site.

Tuesday June 29, 2004
Tracy Simpson reports:
10:00am - Noon: I went up to the mechanical room of MEC 1 to check the monitor to find an incredible surprise... ...WE HAVE A HATCH!!! A beautiful fluff ball poked its head out from under Annie this morning as it lay next to its unhatched egg. I tried to get band numbers of the parents at the site but the wind was howling today and made viewing next to impossible. I will continue to monitor the site until the second egg hatches and we have some clue as to the parents identity. Congratulations to all at the MEC !!

Wednesday June 23, 2004
Tracy Simpson reports:
7:00PM to 9:00PM - I dropped in to check the monitor in the hopes of an exciting development yet 2 hours later, Annie hadn't stood once. What was quite interesting though was that she was incredibly restless, re-adjusting herself every few minutes. Fingers crossed for tomorrow.

Tuesday June 22, 2004
Tracy Simpson reports:
Observations 6:30PM to 8:30PM - I stopped by to visit the mother-to-be at 6:30 this evening to find her fast asleep while incubating her two precious eggs. While watching her on the monitor for approximately 40 minutes she barely moved at all until finally she couldn't resist a stretch and a little preen. Both eggs were visible but no signs of a hatch as of yet. She gently nudged her eggs back under her and fell right back to sleep. At the very least we are at day 24 of incubation. We will be watching closely for the arrival of the new children!

Sunday June 20, 2004
Maya Basdeo reports:
Arrived around 1:45pm. Driving in I could see Cole sitting on the south corner of MEC 1, Annie was not visible. I went up to look at the monitor and had the best luck! Just a few minutes after I turned the monitor and found Annie incubating, she got up and shuffled around and I saw underneath her two eggs. There has been incubation for at least 21 days confirmed at this point. We shall be watching closely to see what transpires in the coming days. I also had an opportunity to talk to the security guards at MEC. They are our eyes and ears when I can't get there to see what's happening. It turns out at about 1:15pm today (just before I arrived) there was a lot of vocalizing by Cole and Annie. The security guards came out to see what all the fuss was about and saw Cole stooping around the buildings and looked like he was chasing something. Shortly after he checked in on Annie who had stayed in the nest box and then flew off southward. Obviously something upset him but he defended his turf and his girl just fine. Good going Cole!

Saturday June 19, 2004
Maya Basdeo reports:
We have NAMES for our MEC Peregrines. The female has been named 'Annie' and the male has been named 'Cole' because those names seem to suit them. The names were presented to us by Danielle Johnston of Oxford Properties. If they are successful again this season it will be three years in a row for Annie and Cole at the MEC. The success of these peregrines is largely due to Oxford Properties who have been excited and supportive of these birds from the very beginning. They have accommodated the birds wonderfully as well as the CPF by allowing the nest box to go in, hosting the bandings of the young chicks, providing property access to CPF staff and volunteers, and generally being very kind and helpful in every interaction. This type of relationship is an example of how conservation-type groups can partner and work with the corporate sector to achieve common goals. It is this type of cooperation that the future of many species at risk depends on. Thank you so much Oxford Properties! Annie remains in serious incubation mode. Over the last few days I've observed her, each time she gets up to adjust herself and stretch she manages to do it with her back to the camera. Maybe she's camera shy? In any case, I can't tell if there are still eggs or a very recent hatch. The nest is littered with moulted adult feathers and the usual remains of bird carcasses. No white downy feathers floating around and no empty eggshell remains to speak of and no food being delivered into the nest by Cole. Cole is usually perched on one of the MEC building corners. He is tending to stay close to home these days, no evidence of this being a two-timing male - unlike downtown Toronto.

Friday June 4, 2004
Marion Nash reports:
We are watching the MEC nest site very closely, with Maya and Tracy doing the spots check as often as they can. The adults are still incubating at least two eggs, and we are unsure as to an expected hatch due to all of the activity going on out there.

Danielle has given us names for the adults, and we are pleased to announce that the adult male has been named "Cole", and the adult female has been named "Annie".

We are unsure about the origin of the adults currently nesting at the MEC due to all of the territorial disputes and ongoing battles for the nest box and territory. We have no idea if the adults birds are in fact banded, but we are watching very closely, as it is only a matter of time until we get a real good look to see if any of the birds are banded. Stay Tuned.

Saturday June 12, 2004
Maya Basdeo reports:
1:30pm - 3:00pm : Arrived at MEC, no adults in sight. Went to look at the monitor to get a good view of any activity in the nest box and found the female still incubating something. Incubating must be fairly hard work because she was sleeping pretty soundly with her head tucked in behind her wing. I waited and watched, watched and waited. She looked so comfortable it made me feel like having a nap myself. Finally she got up to reposition herself and of course, did it all with her back to the camera and I couldn't get a good look at what she was covering. She settled back down after tucking the 'something' underneath her. A little while later though she seemed interested in something on the horizon. I watched her head move from side to side as she scoped out the view. Then I could see her beak moving in a series of kaks and she finally got up and moved to the opening of the nest box. This was great because what she left exposed in plain view were two beautiful eggs! Less than a minute later, the female was back, gingerly tucking the eggs under her and settling down on them once again. It seems as though despite the territorial disputes our MEC pair has prevailed! It is a little late for there not to be even a hatch, compared to the other southern Ontario peregrines, but we remain hopeful that the 2 eggs will yield 2 bouncing baby peregrines!

If we are lucky and have a successful hatch, we will again be calling on volunteers to help us during the 'falcon watch', the time of year when the chicks are taking their first few flights and are at highest risk of mortality. If you would like to volunteer for this period of time please contact the CPF head office at 416-481-1233 or Maya at 647-226-7332. Any help we get is greatly appreciated.

Wednesday June 9, 2004
Mark Nash reports:
We have some great news indeed. It would appear that the territorial battles have indeed finished at the Mississauga Executive Centre, and one of the pairs of birds have won the territory. Unable to really tell just how long the eggs have been there, we will have to watch the site very closely now to detect when a hatch might occur, so that a banding date can be arranged. Any observations at this site will really help us identify a hatch.

Sunday May 30, 2004
Maya Basdeo reports:
4:15pm - 6:00pm : I was lucky enough to get up on the roof of MEC 4 on Friday afternoon and observed one adult in the nest box lying down. The other adult was sitting on the roof ledge of the nest building. There have been reports of arial battles with another female or possibly a pair of peregrines, and I have witnessed several first hand. In spite of that it was apparent an incubation was in process. Over the period of about 40 minutes the adult got up 3 times, tucked either eggs or chicks under it and then settled back down. I then went to the nest building where I watched the monitor of the camera installed inside the nest box. I was there for close to an hour and the adult didn't move at all in the entire time. Definitely incubating but I couldn't tell if they were eggs or very young chicks. Very exciting news! We weren't sure how much pressure these birds were under as a result of the invading peregrines and if it would affect the success of the nest this year. There is hope yet!

Wednesday May 5, 2004
Mark Nash reports:
We have received a number of reports from many regarding the recent activity and happenings that are now taking place at the MEC nest site. While it appears that a attending female is spending some time in the nest box - (observed laying down), we have yet to be able to confirm the presence of eggs. In the interim, Danielle has confirmed what many local observers have been reporting, that a second pair of peregrines have been fighting over the territory, and in particular, fighting over the nest box. Hugh battles have been witnessed by many over the past several days.

Four peregrines have been observed fighting in arial combat, locking feet and talons in an effort to take control of the nest site. The birds screams can be heard from the ground level, and it appears that there is still not victor, that remains in control of the nesting site, and the nest box.

Sadly, if there are eggs currently being incubated by one of the adults, this activity has disrupted the incubation duties, as the nest box / eggs have been left unattended for long periods of time while these battles are raging. All four adults peregrines have been observed in full contact ariel battles.

Sad as it may be, at the risk of a failed incubation, this could result in a failed hatch of any eggs that may be in the nest box. To best understand what's going on, - You know what they say - "Location, Location, Location". We have no idea as yet, who the other peregrine pair is, or their origin, until we are able to get a look to see if they are banded.

Stay tuned.

Fraser Shuttleworth reports:
Have an interesting update for the Mississauga Exec center. Was up there this morning at 2:00 PM and saw both falcons on the SW face where the nest box is. The female was camped out in front of the nest box with the male two sections over to west. Then a 3rd falcon ( a big female) showed up an was actively checking out buildings on the west side of Hurontario. There may have been a another male with her too but I was unable to verify as she was weaving between so many buildings. I had to get going then but she was still patrolling the area when I left.

Monday April 26, 2004
Fraser Shuttleworth reports:
Was up in the Square One area this Saturday and last Saturday. On both occasions that I saw them, both birds were actively flying, chasing each other, around the executive center (SW corner) and the series of condominiums to the South.

Tuesday March 23, 2004
Danielle reports:
Although it would appear that both adults have been very active over the winter months, they have yet to produce any eggs as yet. We are keeping a close eye on the birds, and will advise as soon as they have eggs.

Sunday July 13, 2003
Mussart reports: My husband and I went over to the MEC this evening. We saw what appeared to be one of the adults on the nest. We then spotted one of the juveniles on the roof of No. One building. After a while she flew a considerable distance to the east doing some dives and soars as she went. She looked pretty comfortable. That's all we saw for the half hour or so we were there.

Friday July 4, 2003
Maya Basdeo reports: Very very sad news from Mississauga today. Mark Nash received a call at 7:15am from a security guard at MEC 1 who informed him a bird had been found dead at the side of the building. On arrival I confirmed the bird was indeed one of our 3 young girls hatched this year. The band number corresponded to Artemis. She had not been one of the previously rescued birds and had been flying well up to this point. An employee at MEC 1 saw her flutter down and drop to the ground right beside his car as he was driving to the back of the building. Several minutes later she was discovered dead by another employee walking by. Her death may have been the result of a collision with the building, although there were no obvious signs of head trauma. Once the young birds are flying relatively well, they start to build up their speed and along with it, their confidence. Sometimes over-confidence replaces caution and impacting a building at this point will often result in mortality. Tonga and Orion are still flying well and will be learning how to hunt in the next few days. Lets all hope they continue to do well. The loss of Artemis is sad not only for those of us at CPF but also for many of the staff at the Mississauga Executive Centre, especially the security guards. The security staff, although not directly involved with standing on the street watching the birds, have been almost just as involved as the volunteers on the watch crew. They regularly walk by and ask how we are, how the birds are, take us up to the roof to release birds, store our rescue gear, and generally keep an eye open on our behalf when we're not around - like this morning. We really appreciate their concern and compassion.

Banding Day June 13, 2003
Mark Nash reports: A great Day! With much excitement, and a huge turn out, the second year peregrine banding took place in the lobby of MEC # 1. Hosted by Oxford Properties Group, everyone gathered in the lobby to wait for the young peregrines chicks to arrive from the nest box. Again, this years banding went like clock work, - including the addition of the West Nile blood testing and inoculating. Much to our surprise, the three chicks turned out to be ALL females! Great news for the peregrines, as many of the other urban nests sites have had many male chicks.

The three little girls have been named Tonga, Orion, and Artemus. Photos of the banding have been posted in the Mississauga Centre Photo Gallery for your review.

Tuesday July 1, 2003
Mark Nash reports again: A great day to spend Canada's birthday, watching peregrine falcons!! I love it!! I have been so very envious of all the watchers experiences over the past weeks while they have been out on site watching and caring for the very birds that I have devoted my live to helping. This week, I have had the opportunity to get out to do what I love doing, - watching the juvenile birds at fledging time.

It was a great day, not toooo hot - (at least in the shade), and all the birds were very active. At approx. 2:30 pm, Tonga finally got enough courage to take his second flight. Sadly, not a great strong flight, but a learning experience never the less. After playing "nose tag" with three sets of windows, he finally ran out of energy, unable to gain any altitude, and like a kite with not enough wind to keep it up, Tonga floated down to the street pavement.

By the time I got over to him, he was found with wings stretched out, flat on his stomach, plenty out of air!! I was able to simply pick him up without gloves and the towel, and carry him back to across the street to Linda and the rescue box.

Although not hot in the shade, it was plenty hot in the direct sun light, and the bird was clearly overheated and out of juice.. He was placed in the rescue box, and held there for observation for 60 minutes to allow him to cool down, and allow us to properly inspect the bird before release to the roof. He was given some water with the spray bottle, which he gulped up with attitude! He was taken back to the nest building roof top, and released with his other siblings. As of darkness, he spent the balance of the day on the MEC 1 rooftop, screaming to his parents to be fed.

His other two siblings demonstrated very strong flights back and fourth to the other MEC office towers.

One very interesting note: At around 8 pm, the other two juveniles went back to the roof top of the nest box. The adult female came in with a pure white pigeon, and landed on the nest box porch. She was not chased off by the juveniles (as has been the case for several days), and was allowed to prepare the pigeon just inches away from the flighted juveniles above her on the nest box roof top. The adult female then jumped to the nest box roof with the prepared pigeon, and we watched her hand (beak feed) each of the two juveniles with very tender care!! Although all of the juveniles are more than capable of feeding themselves when food is brought in to them by the parents, this is very unusual that the adult was not pushed away after a food drop.

Sadly, Tonga did not get any of this meal, as he was still on the building roof top, - screaming as usual for food to be delivered to him.

Tuesday July 1, 2003
Mark Nash reports: For most of the day, Tonga, Orion and Artemus spent most of their time on MEC #1 enjoying the cooler temperatures and sunny day. Although only two of the juveniles were visible at any given time throughout the better part of the morning and afternoon, short flights were observed from the nest building to MEC 4 and MEC 2 and back to MEC 1.

At approx. 2:30 pm , Tonga left one of the ledges at MEC 1, and attempted another flight with the ease of an overloaded 747 Jumbo jet. Although a long flight, Tonga lost altitude as she bumped into the windows at MEC 1, then over to the windows at MEC 4, and finally over to MEC 3 where she did a yet another face plant into the upper windows. None of the window face plants were hard, but she is quickly learning that the windows are a impenetrable object. She slid down the west site of MEC 2, approx. 15 floors, - wings open and nose planted to the windows, finally coming to the ground. I was seconds behind her, and she was scooped up in my hands moments after falling to the ground. I found her flat on the ground, wings stretched out, and out of breath laying on the pavement in the court yard of MEC 2. She appeared uninjured, but out of juice! She was retrieved and placed in a rescue box, and held in the shade until her she cooled down and could be inspected more closely.

She was later released back to the roof top of MEC 1 after she was inspected for injuries, and spent the balance of the day on the upper roof ledge running around trying to attract her parents attention. Her other siblings made several very strong flights throughout the day to the other MEC buildings, both returning to the nest box by the evening.

Surprisingly, the adult female was observed bringing in food to the nest box on two different occasions and hand/beak feeding both Orion and Artemus. This is Very strange given that all three birds have fledged, and very capable of eating the food on their own when provided to them by their parents.

Monday, June 30, 2003
Maya Basdeo reports: Linda and I arrived approx 06:00 to find 3 birds on the nest ledge. We initially counted them as two juveniles and one adult thinking Tonga remained on the nest building roof. As we watched them, Linda noticed one of the birds in particular who, sitting on the ledge with it's back to us, was quite busy preening, and preening some more. That was our first clue but we had to wait until the bird turned to face outwards to confirm it was Tonga. She'd made it back to the nest ledge either late Sunday evening or before we arrived this morning. Tonga spent most of the next few hours sitting beside the nest box preening, while her sisters hopped on and off of the top of the nest box and in and out of the trough underneath the nest box. Approx. 09:00 Tonga was still preening, one of the chicks was hopping from ledge to ledge and one chick was sitting on the roof of the nest box. The chick sitting on the roof of the nest box took her first flight towards MEC 2 and was closely followed by mom, who helped steer her along. They circled around MEC 2 once and then the chick landed on the roof of that building. A few moments later she was spotted sitting on a column on the NW side of the building. She made a few forays across the very top ledge of the NW side of the building until her next takeoff at 12:05pm. She flew in a wide arc back towards the nest but was not quite high enough to land. She ended up just touching off the glass and made another wide arc towards the SW side of MEC 3. She tried to hang on to the almost nonexistent window panes and did the "bat maneuver" - which didn't last long - so she pushed off again and flew around to the SE side of MEC 3 and crashed against the wall section between the windows. She tried the bat here again but there was nothing for her to grip onto and she steadily dropped/fluttered all the way down and landed on the concrete in front of a group of MEC employees who were walking by. Judging by the expressions of all the parties concerned, I'm not sure who was more surprised - the people or the bird!

As fledgewatchers, we each watch the little birds like a hawk (no pun intended) and as this scenario was unfolding, Bruce, Linda and myself were all tracking the young chick's progress as soon as she took off from the ledge. We are stationed at different points around the nest site and communicate via 2-way radios so by the time a bird ends up on the ground we are there waiting. This time was no exception and the three of us immediately had the little peregrine in a 'safety bubble' - basically we formed a perimeter around the bird so no one could approach her, of course having the best of intentions but would end up scaring her into a panic, we stopped cars that were travelling through the parking lot in the bird's direction from hitting her and this gave her the few seconds she needed to collect herself, find a flight path and take off again.

The chick took off across the parking lot around to the back of the building but couldn't gain much height and landed somewhat haphazardly in a nearby tree. This seems to be the year for tree-hugging peregrines. The chick stayed there all day until about 9pm - and so did the fledgewatch crew. Throughout the balance of the day the 2 chicks who had been on the nest building did some ledge-hopping and some vocalizing to the parents but did not take off. As the day was winding down we made our way to the area of 'treebird' (this was how we referred to her throughout the day, not knowing which bird she was). Because she was so low in the tree we had the rescue equipment close at hand and it really did come in handy about 9pm when as treebird was trying to reposition herself in the tree she ended up on the ground. Linda and I worked quickly to contain her and get her in the rescue box. Because it was so late in the day, we didn't want to take the chance leaving her on the ground for the night where she'd have no defense against raccoons, dogs, or any other potential predator. Not to mention car and human traffic.

We checked her band number and treebird's real name is ORION. She is the youngest of the 3 chicks at MEC but you would never guess that judging by her attitude. By the time Orion realized what had transpired, she was a little cranky. Actually, she was A LOT cranky. She was so mad that every single feather on her body was standing out on end, making her look 3 times her actual size. While Bruce stood watch from the street, Linda and I made our way to the roof so we could quickly release Orion (who was growing crankier by the second). After giving Orion a little drink of water, Linda and I were escorted up to the roof by Oxford Properties Security. The entrance to the rooftop is via a steel rail ladder and through a hatch which opens directly onto the roof. It reminds me of something you'd find in a submarine. I scooted up the ladder, opened the hatch and poked my head up and around to make sure there were no peregrine parents waiting to ambush me when I got out there. With a rope attached to the rescue box, Linda and I made our way up the ladder. I went up first and Linda was behind me supporting the box and preventing it from swinging around. I hopped up onto the roof, hoisted up the rescue box containing the amazingly mad, cranky Orion, and positioned the box for the release. I placed the box with the opening pointing towards a cement wall AWAY from where I was standing and my access to the ladder. It took a few moments to open the box because every time I tried to pull open the gate, Orion would claw at the grate with all her might. I was very very happy she seemed to hate me so much because she'll likely avoid people, but I was a little concerned for my own welfare. Once I got the box opened, Orion dashed out and turned right around to glare at me. She did not attempt to get away, or seek shelter, or even call for her parents....she just glared and stared and seemed to even frown. Without taking both eyes off of her entirely, I lowered the rescue box down to Linda and told her to make room for me, I was coming down. As I was retreating, Orion started stomping towards me - she looked like she was in attack mode. I backed away from her and got my foot on the first rail of the ladder. I thought I was safe, but as I lowered myself down the ladder, Orion started moving towards me at a faster pace. I guess she perceived me as getting smaller and more manageable. As soon as I got my footing I went down the ladder, with Linda beneath me, so I was about 3 feet from the opening to the roof. I really felt like I was in a horror movie and this bird was coming to get me. I was half scared, half laughing. Linda hadn't seen what had transpired between me and the bird and she reminded me to close the hatch on the roof. I told her I needed to wait and make sure it was safe because Orion was after me.

Linda thought that was hilarious and that I was ridiculous (peregrines don't chase people) until, seconds later, a pair of glaring eyes abruptly appeared at the hatch opening. Orion jumped on the edge of the hatch and glared at me. She bobbed her head and started to shuffle along the edge, trying to figure how to get me (at least that's what it seemed like). In any case, she seemed to be trying to navigate her way back into the building. I was still near the top of the ladder and Linda was right below me...there was nowhere to run. The security guard who had escorted us up was making his way towards the door. Linda was quick-witted though and scaled down the ladder, grabbed my spray bottle of water and handed it to me. I sprayed some water up towards Orion. She just kept glaring at me. Linda passed me a towel (a bright pink towel - not terribly intimidating) which I waved around. Orion then hopped off the opening, giving me my chance to close the hatch door. Whew! We were safe!

I think the whole rescue was more stressful on Linda and I than it was on Orion. We made our way back down to the lobby of MEC 1 and met Bruce and Mark Nash outside. We were laughing about our ordeal until we looked up. There was the silhouette of a peregrine falcon pacing the very top building ledge...looking right down towards us (or towards me). We walked to the corner of the building to our vehicles and the peregrine walked along the ledge above us, following us. Orion stationed herself on the corner of the building and glared and glared at us until we left. I wonder if peregrine falcons have a good memory...

Linda, Bruce and myself would like to send a big, big thank you to all of the security staff at Oxford Properties at the Mississauga Executive Centre for allowing us access to the roof so we can release the young chicks, for allowing us to recharge our phones and for being so helpful to the Canadian Peregrine Foundation in general. Thanks guys! You're the best!

Linda Woods reports:
08:50 - After two days of "tree hugging" fledgling # 1 ( Tonga) finally took a second flight from a tree north of the bridge and ended up across the street to M.E.C. # 2. She didn't gain any height and came to land on a two foot wall. She wasn't there long and took off again and entertained us with a " bat maneuver". This involves clinging onto the side of buildings and window ledges and gives the appearance of a very large bat. After a few moments of clinging she dropped down into the shrubbery below. With a little encouragement we coached her out and into the open where she would be able to see "air space" Well she wasn't interested in anything but preening, preening and more preening and when that was done she preened some more. During her little stint of wall sitting a red squirrel and a small bird dropped by the see what all the preening was about. Her visitors did not stay long. After hours of sitting and preening she decided to move and eventually came to the sidewalk. She was retrieved by Mark Nash, and Maya and myself released her back to the roof top of MEC 1 (the nest building). . She had no apparent injuries ( I don't think she hurt herself preening) she had a few squirts of water and was released from the roof-top of the office tower. ( Photos of Tonga's Adventures ) At. 8:45p.m. the adults were seen circling above the office tower directly above the area she was released. Her other two siblings have graduated from wing flapping 101 to the artistic maneuvers of ledge hopping. The second oldest has advanced to making all the way across the east side of the nest building. The youngest has only made it half -way. I expect one of the two to fledge tomorrow.

Bruce Massey reports:
Just a quick update on the fledge of the female immature @ Mississauga Executive Center. It happened @ 11:15 AM, with the female flying up to the top of the Nest Box. Then as one of the adults flew over from 3 Robert Speck Parkway, the female that was on the nest box started to flap. As I started to break down my spotting scope I glanced up and she was off. She flew out to the north west accompanied by both her parents, she swung back to the front of the nest building and then headed back to the nest building. She glanced off the windows 2/3 to 3/4's of the way up, she dropped immediately down the front of the nest building. I of course thought the worst, but as I looked up the immature flew low over the watercourse about the height of the trees, and disappeared behind 3 Robert Speck Parkway. One of the adults followed and then came back without the immature. We didn't see the fird again throughout the day, however we are hopeful we will find her tomorrow. This optimism is not without precedence. Two years ago an immature male (Trillum) was lost down an airshaft @ the King Edward and was found 9 days after weighing about 1/2 his weight, but he recovered to fly again.

Maya Basdeo reports:
19:00 2 chicks in nest box - one just inside and one sitting on the front porch - 1 chick on the nest ledge. No adults in view. Gradually 2 chicks from the box ventured onto the ledge beside first chick. 20:05 adult male brings food in. All three chicks sat in an assembly line fashion as they were each fed. The one at the end of the line was protesting a great deal to being last. Very very hot sunny day, chicks relatively lethargic.

Volunteers needed!
The Falcon Watch will be starting on Monday June 23! We need volunteers to help with observing the 3 chicks as they take their first flights. We welcome staff members at MEC to participate over lunchtime, before or after work - even if it's only for a 1/2 hour at a time. We are looking for people to participate between the hours of 5am and 9:30pm - anytime between dawn and dusk. Please call Linda Woods at 416-580-7222 to arrange dates and times or email us at and we will get back to you.

Friday, March 28, 2003
Mark Nash reports: 
Great news - as both adults were on site and in my view upon my arrival! The adult female was on MEC #1 just to the right of the nest box on the corner - roosting and watching the window washers on MEC #3. The male was on his usual spot on MEC #2, watching the box and his mate.  Both looked very settled, and both with full crops!! We then attended the nest camera monitor to look into the nest box. There were no eggs as yet, but a very large scrape (bowl) in the pea gravel, and it appears that it's very close to laying some eggs.

Wednesday August 14, 2002
Jonathan Vezina reports: 
I have noticed two peregrines playing with a catch flying above the parking lot of 33 City Centre Dr twice in the past week.  They seem to enjoy resting on the ledge of the second last floor of 55 City Centre Dr on the northwest corner.  I am truly amazed by their acrobatic flight skills and would like to thank all those responsible for the nest box at 1 Robert Speck.  They are an awesome sight to see.

Saturday July 27, 2002
Marcel Gahbauer reports: 
The Mississauga fledglings have all been named - the female is Missy, while the two males are Jack and Jake.  All appear to be flying quite well now.

Tuesday July 23, 2002
Linda Woods reports: 
09:30 On arriving and one circle of the buildings, I didn't see any of the birds in the area.  09:55 One immature on the KNEFF antenna, it flew off towards the # 2 tower of the executive centre.  10:30 Immature off the # 2 tower and appears to be chasing off an adult that had been sitting on the corner. A lot of vocalizing can be heard.  10:40 Immature on the # 4 tower. No others in view.

11:20 One adult sitting under the word "centre" on the # 2 tower, it just finished feeding one of the immatures. The adult remained in view cleaning it's beak and the immature went out of sight.  11:45 The adult remains on the # 2 tower sitting under the word "centre"  One immature is on the north side of # 33 City Centre (the building with the blue awning) That one went out of my view but I did see one of the immatures return to the north side of the nest building and tuck it's way into the back of the ledge. It must be the youngest one who likes that corner of that ledge. Not a lot of activity from then today. Perhaps they like the evening fly-arounds.

Wednesday July 17, 2002
Linda Woods reports: 
9:30 am: Adult female is on the north-east corner of #2 tower.  Single juvenile is seen tucked away in the back of the north side of the nest building. (This one does not appear to have taken it's first flight as yet. I think this is the one that hopscotches across the ledges.)  Two peregrines on the # 4 tower. One I believe is the subadult male. He is sitting in the exact same spot as he was last week-end. The other, is a juvenile and is sitting on top of the "camera" equipment above the subadult male. This juvenile likes to climb into the actual camera mountings and pancakes flat out. Viewing from street level I could see this one climb onto the mountings. The next time I looked it appeared it had gone, but when viewing from the upper levels of the adjacent building, I discovered it was still there and had gone into the frame of mountings and would not be visible from street level.

All four remained in the same positions until approximately 11:30 a.m. The subadult male took off and was hunting over and beyond Square One Plaza. During this time I did not see a 5th peregrine (third immature).

12:30p.m. None of the peregrines are in view from street levels.

Wednesday July 17, 2002
Linda Woods reports: 
This morning when I arrived at MEC, I didn't see the juvenile on the lower ledge where he was last night. Yuki and I searched the area once again but couldn't find him. Security took me to an upper level office to look down but did not see him. Finally at 4:30ish I saw two juveniles on the ledge beside the nest box and one juvenile had flow from # 3 roof-top over to the nest building roof-top. Mom was on the nest box roof. Dad was not seen. I guess it's the young female that likes hopscotching across the window ledges.

Maintenance was on the roof to the nest building and the adult female certainly let them know she was around.  Later on in the afternoon, the adult female was swooping and stooping the roof-top of #2 tower. Very odd, lots of vocalizing and swoops and dives. I watched for a while and then another bird came off that roof and headed towards the south-east. Don't know what it was, but it certainly wasn't a gull, pigeon, crow or kestrel. The adult female did not give chase and went back to the nest building.

Tuesday July 16, 2002
Marcel Gahbauer reports: 
A brief update: all three juveniles are now accounted for - it appears that the female is somewhat younger than her siblings and has not been as active, i.e. has been hiding from view much of the time below the ledge where the two males were exercising throughout the weekend.  One of the males was found this morning on a low roof, but appears unhurt.  More details to follow.

Linda Woods reports:  I arrived at the M.E.C. just before noon and did not have the 2nd missing juvenile in sight. Yuki and I did a complete search of the entire grounds. I made my way back to the  place the young male was last seen. I wasn't there 5 minutes and it popped up onto the ledge. It had been there the whole time out of the sun. The lower roof of this building is difficult to see unless one is viewing from the upper levels of the adjacent building.

2:30p.m. Mom brought food to the other three that were on the nest building. A lovely light coloured pigeon. She was even attentive to carry the prey to the next ledge over to ensure the last young one had a bite to eat. All the while the third immature remained on the lower level of #2 building. I headed for home at 7:15p.m. and Yuki remained on site until 8:00p.m. Yuki reported on her departure that the young immature remained on the lower roof  in the same area of # 2 building and the other two were at the nest ledge.

Sunday July 14, 2002
David Pfeffer reports: 
The two juveniles continue to make attempts at flying.  When they give up on that they generally start playing with each other.  The male at one point walked up to Sal and bit his toe!  No wonder the adults tend to perch well away from the young ones.

Sal's moult is progressing well.  His back is well covered in adult feathers, but he really does look like he flew through a fan.  It will be interesting to see if he will be as dark as his mother, Madame X from Hamilton.  It is easy to see why Sal was thought to be a female.  This bird has a really wide body and a large head.  In flight, however, the thin sharply pointed wings give away his true nature.

We are still missing the third chick.  We hope to get access to the roof tomorrow and solve this mystery once and for all.

Saturday July 13, 2002
David Pfeffer reports: 
Bruce Massey spent the day at the Mississauga Executive Centre (MEC) and only saw two juveniles.  It is possible that the third spent the day a the lower part of the ledge.  However, the other two were constantly jumping up and down that ledge, so there is the possibility that the missing male has fledged.  Our searches around the area have turned up nothing.  Therefore, we are asking that people in the Square One and MEC area keep an eye out for a young Peregrine. 

Monday July 8, 2002
Marcel Gahbauer reports: 
David Pfeffer has provided me with the details from the banding of the chicks at Robert Speck Parkway.  The female was determined to be 31 days old, weighing 841 grams.  Her two brothers are both 32 days old, with weights of 589 and 643 grams.  Sal was not overly aggressive at the nest, but the female (still unidentified) did come in to attack when her chicks were removed.  Some photos of the chicks have been posted in the Mississauga Gallery.

Mark Nash informed me that the tenants of the Mississauga Executive Centre will be naming the chicks, hopefully before they start taking flight around the end of this week.  The banding event was very well attended, and was a great success for all involved.

Friday July 5, 2002
Marcel Gahbauer reports: 
Early reports from this morning's banding indicate that there are two male and one female chick at the Mississauga Centre nest.  More details to follow.

Sunday June 30, 2002
Marcel Gahbauer reports: 
Photos of the adults in Mississauga Centre have been added to the Mississauga gallery.

Saturday June 22, 2002
Brandon Holden reports: 
While at the Mississauga Executive Centre today we could read Sal's band; however we could not read his mate's band which is black over green on the one leg and purple on the other. The green band appears to be extremely faded or dirty and no numbers/letters could be seen.

While at the Center we did see Sal bring a kill into the nest box, and his mate had two failed captures of Rock Doves. At one point the two adults were hunting together, both going from different angles at the same bird. Last year I helped at the Hamilton falcon watch and it is interesting to see the change in Sal's plumage. He is now appearing to get the grey/white adult plumage while last year he was very brown/taupe colour. Both birds spent long times perched on the corners of different buildings and looked to be enjoying the cooler temperatures.

Marcel Gahbauer comments:  The purple band on the female's other leg confirms the earlier suspicion that she is from the US Midwest ... but until someone is able to read the characters on the black/green band we won't be able to say more than that.

Saturday June 8, 2002
Marcel Gahbauer reports: 
Bruce Massey spent several hours today observing the Mississauga Executive Centre nest.  He was able to confirm that there are three chicks, all of which appear to be 4-5 days old (consistent with the first feeding observed on Monday).  Bruce was also able to get additional information about the adults.  The male is clearly a second year bird, and Bruce was able to read the characters on his black leg band.  Interestingly, they correspond to Sal ... who was thought to be a female at the time of banding in Hamilton last spring!  It appears that Sal may simply have been an unusually large male.  As for his mate, she has a black/green leg band, indicating that she is from the US Midwest.  No further details on her are available yet.

Monday June 3, 2002
Marcel Gahbauer reports: 
It appears we have a hatch in Mississauga!  Today around 5:20 pm, Danielle Scanlon observed the male beside the nest box, then flying over to MEC #3 for something to eat.  More significantly, Mark Chojnacki had the following observation:  "At 5:53pm I observed the female fly over from MEC 1 to MEC 2 and take a kill from the male. He had been plucking the kill up to this point. My guess is that the kill was a grackle."  He added that the female then headed back to the nest with the food.  Since peregrines generally do not bring food to the nest until there are chicks, this suggests strongly that at least one has hatched.

Thursday May 30, 2002
Marcel Gahbauer reports: 
Late this afternoon, Mark Nash, Bruce Massey, and I visited the roof of #3 Robert Speck Parkway to check on the status of the nest at #1.  The female made a couple of loops past us, then settled on a corner of #2, to our south.  We had a good look at her, and it appears that she is a second year bird, based on the large amount of brown remaining on her back and wings.  She also appears to have dark bands on both legs, but we were not close enough to identify them more precisely.  Throughout our brief period of observation, the male remained on the eggs in the nest box, turning his head periodically, but otherwise motionless.  This suggests that the hatch is likely still at least 2-3 days away, as the adults tend to become restless within the last ~48 hours of incubation, and often the female takes over entirely during that time.  We look forward to hearing of a hatch at this site some time next week.

Thursday May 23, 2002
Marcel Gahbauer reports: 
Mark Nash tells me that he visited the rooftop opposite the nest yesterday, and found the female still in full incubation mode, suggesting that hatching is still a few days ahead at the earliest.  It appears the onset of incubation was not determined accurately - but this is an easy mistake to make in such a situation!  As a result, the hatch is likely to occur later this month, or possibly even into early June.

Saturday May 11, 2002
Marcel Gahbauer reports: 
Observations relayed to us by Mark Chojnacki suggest that incubation began some time around April 17.  Based on an incubation period of approximately 33 days, we can expect chicks to begin hatching some time around May 20.  Adults flying to the nest with prey will be our best indication that a hatch has occurred - anyone observing such behaviour is encouraged to report it to us.

Wednesday May 1, 2002
Marcel Gahbauer reports: 
3:30 pm - Mark Nash has just phoned to let me know that he has been observing the MEC nest box from a neighbouring building with a scope, and that the female peregrine is incubating in the box.  She did not get off the nest during the period of observation, so we do not know how many eggs there are.

Monday April 22, 2002
Mark Chojnacki reports: 
Just a quick note to let you both know that I observed the Mississauga MEC peregrine pair mating at 2:40pm atop the northeast corner of 2 Robert Speck Parkway.

Wednesday April 17, 2002
Mark Chojnacki reports: 
The pair of Peregrines at the MEC (Mississauga Executive Centre) seem to be sticking quite close to 1 Robert Speck Parkway and the platform on the southeast side.  Just a few minutes ago, I observed both birds in flight between 1 RSP and 2 RSP. The male gave a nearby Ring-billed Gull a major fright by stooping on it. On Monday, I was distracted as feathers floated down in front of my office window as one of the Peregrines plucked a kill atop 1 RSP.

Monday April 15, 2002
Marcel Gahbauer reports: 
Over the past month reports from this site have been relatively few.  However, a few office workers in the Mississauga Executive Centre complex do continue to see a pair of peregrines regularly, so it would appear they are at least territorial.  Whether they have eggs remains to be determined, and may be difficult to confirm given the location of the nest box on a high, sheltered ledge.  In fact, if they are nesting we may not be absolutely certain until the chicks start moving about!

Thursday March 14, 2002
Mark Chojnacki reports: 
I observed a pair of Peregrine Falcons at 4pm today doing what appears to be a courtship flight around the MEC (Mississauga Executive Centre). I have had several recent sightings of at least one bird with a kill on various dates over the past couple of weeks.

Bruce Massey reports: 
I spent several hours at Mississauga Central on Saturday, and managed to succeed in finding the tiercel that Mark Nash and I saw when we installed the nest box two weeks ago, and a sub-adult female in the afternoon.

The female, was definitely making advances at the male, twice she flew at him, to land beside him, and twice he moved away.  The second time, the male flew down onto a window ledge, and female flew down to the same ledge, but maybe 30 feet away.  After 10 or 15 minutes, she flew beside the male and proceeded to make a series of head motions.  The male seem to be interested but wary, and then moved 20 or 30 feet down the ledge again. The female flew west, after about 15 minutes.  I found the female, about half an hour later three buildings west of the building the male was on. I managed to put the telescope on her, and she was definitely sub-adult and banded.  

Monday January 7, 2002
Mark Nash reports: 
We have installed the nest box at the Mississauga Executive Centre (#1 Robert Speck Parkway) last week on January 3rd as planned.  Bruce Massey and I attended from CPF, along with Ms. Danielle Scanlon (assistant Property Manager - Oxford Properties Group), with several very helpful maintenance hands from the MEC.  In addition, Mr. Jeff Stewart, from Tractel Ltd., Swing stage Division was on hand to put the swing stage together, and set it up for us.  He also attended with me on the swing stage, and assisted with the installation of the nest box.  We arrived at 9:15 am, and started at approx. 9:30am.  We finished at 3pm.  It was an all day event, very cold and windy. 

The pea gravel and tools were loaded into the swing stage, and Jeff and I climbed inside and then ascended to the 17th floor level where the ledges are.  The nest box weighs several hundred pounds (constructed of 2x6, 4x4's, and 3/4" plywood, a few 4x4's, 2x2's, galvanized screen mesh, five boxes of 3" screws, and a gallon of steel blue colour lead free paint.  Put four bags of 18kg pea gravel and there you have it).

The box was paid for by the Mississauga Executive Centre, with the support of Oxford Properties Group.  Construction was by Mark Nash of the CPF.  The Mississauga News was on hand to photograph the event (from the roof), and in addition, Jeff Stewart (from Tractel) also took some good photos (see the Mississauga Photo Gallery)

NOW FOR THE BEST NEWS!!!   At two o'clock pm, while we were on the swing stage at the nest ledge, an adult male peregrine came in and buzzed us while we were on the ledge itself, tying down the nest box.  Bruce was on the roof and alerted us of the incoming bird.  Danielle Scanlon (from Oxford Properties Group) was on the sidewalk at street level, and saw a second peregrine just behind our view at the same time.  It would appear that at least one, if not both (or at any rate two) peregrines are still very much alive and well, and watching the ledge!!   Things are looking good for this territory.

Friday December 21, 2001
Marcel Gahbauer reports: 
Our hopes were high for the first ever successful peregrine nest in Mississauga this past spring, but unfortunately none of the three pairs were able to raise any young.  To increase their chances of success for next year, the Canadian Peregrine Foundation has prepared nest boxes for two of the sites.  CPF Director Mark Nash delivered the first box to the Lakeview Generating Station last Friday, and we expect it to be installed shortly; details and photos to follow.  A second box will be delivered and installed at the Mississauga Executive Centre in early January.

Saturday July 28, 2001
Marcel Gahbauer reports:  
The latest news from Mark Chojnacki at the Mississauga Executive Centre is that a peregrine is still being seen fairly regularly around #1 and #2 Robert Speck Parkway.  The most recent sightings were on July 16 at 5:22 pm (flying past and spooking the pigeons), July 20 at 3:55 pm (flying past), and July 25 at 5:42 pm (flying past and then landing on #4 Robert Speck Parkway).

Wednesday May 16, 2001
Mark Chojnacki reports:  
I again observed two birds in the vicinity of the MEC today. At about 1:10pm, I saw one bird fly near #2 Robert Speck Parkway and then I noticed that a second bird was perched below the MEC symbol on 2 RSP.  The flying bird executed some spectacular aerial manoeuvres for several minutes between 2 and 1 RSP. Not sure if it was for the benefit of the other bird or not.

Friday April 27, 2001
Suzy Paquette reports:  
We are still seeing only one bird on a daily basis here at the Mississauga Executive Center, actually I am looking at it right now. It usually sits on the sunny side out of the wind on #3 or #4.  Unfortunately a second bird still has not been seen.

Thursday April 26, 2001
David Pfeffer reports:  
6:00p.m.: Bruce Massey spotted a male Peregrine sitting on 2 Robert Speck Parkway.  We are not sure if this was the same male we saw half an hour earlier at Lakeview.  Bruce was unable to get a close enough look at the male to spot similarities.

Tuesday April 24, 2001
David Pfeffer reports:  
Today around 6:30p.m. I finally spotted a Peregrine at #1 Robert Speck Parkway.  It was eating either a small bird or a morsel of something bigger.  I never saw the bird land, so I believe that it was further in the ledge and then decided to come out to the edge and eat.   This Peregrine has fairly wide malar stripes and some streaking on the breast feathers.  It didn't appear to have the salmon wash on the breast feathers.  

Friday April 20, 2001
Mark Chojnacki reports: 
I am continuing to have sightings of Peregrine Falcons at the Mississauga Executive Centre culminating in today's repeated views of two birds at once (1:25pm and 2:25pm). Just a few minutes ago, I was treated to the sight of both birds flying toward my window (after leaving the vicinity of 2 RSP) with one bird carrying food! Could there actually be a nest on top of 1 Robert Speck?

Sunday April 8, 2001
Marcel Gahbauer reports:  
Recent observations have indicated that there are again peregrines in Mississauga.  The question is, are we hearing about one pair which travels between Lakeview Generating Station and the Mississauga Executive Centre, or are there two separate pairs?  With a distance of less than 8 kilometres (5 miles) separating the two sites, either scenario is very much possible.

I set out today to try to investigate this mystery.  The first stop was at the Mississauga Executive Centre, where over a span of half an hour I observed a considerable migration of birds heading north over the four building complex, including 3 Turkey Vultures, 2 Red-tailed Hawks, 3 flocks of Double-crested Cormorants, and several small flocks of Canada Geese, Common Grackles, and Red-winged Blackbirds.  The fact that none of this bird activity elicited a response from a peregrine made me suspect that they were not in the area.  There was also no whitewash visible on any of the four buildings along the west end of Robert Speck Parkway, though the presence of a swing stage on #4 suggested that they may have just had their windows washed.

However, shortly before giving up, I made a visual sweep of the area to the south, and spotted a lone peregrine circling high over the pinkish Edward Jones buildings southwest of Hurontario and Burnhamthorpe.  The impression I got from it was that it was a male, though at this distance it was impossible to be certain.  It drifted higher and higher, also gradually heading south, and I eventually lost it from sight.

I then headed south myself, to Lakeview Promenade Park, just west of the Lakeview Generating Station.  No sooner had I started to systematically scan the towers of the plant for peregrines, than I heard an agitated call and looked up to see an adult female heading north with a definite sense of purpose.  It quickly became evident that she had set her sights on a hapless Red-tailed Hawk which happened to be flying past.  The peregrine made several vigorous attacks at the hawk, driving it down to shelter on one of the transmission towers, then returning to attempt to drive it away from that refuge as well.  At that point two crows arrived to join the fight, and the peregrine turned her victim over to them.  She then played around in the wind for a few minutes.  Several times she almost landed on the west edge of the building, but caught a gust of wind and lifted up again.

Though only one bird was seen at Lakeview, the energetic response of the female to a non-threatening intruder bodes well for the possibility of this being a nest site.  It's possible that there are already eggs, and the male may have not been in evidence because he was incubating.  Even if there aren't eggs yet, he may have simply been letting the female take care of territorial defense, as is often the case with peregrines.  Things look promising for this site.

In conclusion, it's still difficult to say how many peregrines there are in Mississauga, since only one was seen at each of the two locations today.  However, given that the female's behaviour at Lakeview strongly suggests a nesting attempt, I suspect the adults from that site would not be ranging far inland at this time of year, so my hunch is that the peregrines being seen at the Mississauga Executive Centre are different ones.  We are of course very interested in learning the identity of all of these birds, especially since we are curious whether any of them are Toby or Alberta (displaced from Etobicoke last spring).  If you spot any of the Mississauga peregrines, please help us continue to piece this puzzle together by e-mailing your sightings to

Tuesday April 3, 2001
Mark Chojnacki reports:  
I can confirm that I had my first sighting (for this year) of a Peregrine Falcon from my office window yesterday at 1 Robert Speck Parkway.

Monday April 2, 2001
Suzy Paquette reports:  
I have a feeling the reason only one falcon has been spotted is the fact that there may be a nest on 1 Robert Speck Parkway.  I have watched feathers and other stuff falling from the roof and have very clearly seen a falcon swoop up the building calling out as it goes up and it sounds like there is definitely more than one bird.  Also, there are no more local hawks and most of the crows have decided to leave. This one bird that is seen seems to keep everything away from this building.

Marcel Gahbauer comments:  The Mississauga Executive Centre on Robert Speck Parkway offers a number of suitable nesting opportunities (see the Mississauga photo gallery), and we have long expected peregrines to settle here.  We encourage anyone in the area to forward reports to us at and hope to have further news to post shortly.

Thursday March 29, 2001
Suzy Paquette reports:  
I am sitting here at #1 Robert Speck looking outside at #3 Robert Speck and there is 1 falcon which has been around for about the last week, especially on bright sunny days, seems to enjoy perching on the sunny side of #3. This bird seems to be alone.

Tuesday January 16, 2001
Lois Todd reports:  
On Saturday January 13 I was standing in the parking lot of Hyland Farms on Hwy 10 and Milverton when a Peregrine Falcon flew overhead and attacked a small group of pigeons on the roof of the building across the street, capturing one.  The Peregrine flew off, with it's prey, behind the building, so I don't know where it ultimately landed to dine.  I usually see a Peregrine around the intersection at Hwy 10 and 403 (although I haven't seen that one for a couple of months), but I hadn't seen one in this area before.  Due to the poor sky conditions, I have no further details on the bird re plumage, etc.

The sighting was at Hwy 10/Hurontario and Milverton (just south of the 401 on Hwy 10). The building the pigeons were roosting on was the red-marble stepped office building on the north-east corner of the intersection.

Monday January 15, 2001
Marcel Gahbauer reports:  
Since Suzy Paquette's report a couple of weeks ago, we have received a number of other reports by phone and e-mail of peregrines in the Square One area.  Additional sightings have come from Port Credit harbour to the south, and the Winston Churchill / Upper Middle Road area to the west.  It's impossible to conclude at this point whether all these sightings involve the same birds, but the likelihood is that there is a single pair which is roaming across Mississauga and surroundings in search of a good nest site for the rapidly approaching breeding season.  

We are hopeful that a new nest site will develop, and ask for your help in assisting us to track down the location so that we can ensure that any potential nest site is fully protected from disturbance - if you spot peregrines anywhere in Mississauga or beyond, please e-mail us a report at detailing your observations.

Suzy Paquette reports:  
Over the last week or so, I have seen a pair of Peregrines flying together between the 4 buildings on Robert Speck Parkway, and have also seen them bordering #10 highway in the early evening.  They put on quite a show today, chasing each other and flying under each other and touching. Unfortunately there were high winds today and some snow, so determining whether or not they have leg bands is difficult.

Suzy Paquette reports:
  Today again for the last half hour or so a falcon has been sitting on the north side of #2 Robert Speck Parkway at the Mississauga Executive Centre.  Everything seems to be ok and he/she is looking around.....unfortunately no one in the office has a pair of binoculars to see the leg band.

Mark Chojnacki reports:  A Peregrine Falcon has just flown into the area and is now perched on the west corner of #2 Robert Speck Parkway. Unfortunately, I did not bring my binoculars with me today...

Marcel Gahbauer reports:
  It has been a while since peregrines were reported in this area, but earlier this month Mark Chojnacki was again fortunate enough to spot one on the Mississauga Executive Centre sign.   The age and sex could not be determined at the time.

Evidently this site continues to attract peregrines.  It's possible that the peregrine seen recently was Alberta, since she appears to have been displaced from the Etobicoke site, but has likely not gone far (given that she has made several return appearances in Etobicoke to date).  The Mississauga Executive Centre is only approximately 10 km to the west, and would be visible to Alberta from Etobicoke.   Perhaps more importantly, the four buildings along Robert Speck Parkway were designed by the same architect who built the Clarica Centre which Alberta has called home since 1997.  So it is definitely worthwhile to keep an eye on these buildings in Mississauga, in case anything develops this spring.

Mark Chojnacki reports:  A peregrine (sex and age unknown) has appeared at the Mississauga Executive Centre. It appeared near 1 Robert Speck around 1:20pm and flew up to perch on the northwest side of 2 Robert Speck directly under the MEC sign.

Tuesday May 4, 1999
Marcel Gahbauer reports:  Late last week Bruce Massey told me that he had spotted a male peregrine at the Mississauga Executive Centre (more details to follow).  This is the first sighting we've heard of in close to a month, and raises the question whether this was the same bird as last time, and if so, where it has been in the meantime.  It could be that it has established a territory elsewhere in Mississauga, and only occasionally gets over to the Square One area to hunt.  I checked all four of the office towers on Robert Speck Parkway this afternoon, but could spot only pigeons on the ledges and roofs.  

Monday April 5, 1999
James Hartshorn reports:   I spent about 30 minutes on Sunday April 4 observing a female Peregrine Falcon on the Mississauga Executive Centre building at 2 Robert Speck Pkwy. The building is located on the southeast corner of Hurontario (Highway 10) and Robert Speck, just south of Highway 403 in Mississauga (just east of the Square One mall). The falcon was seen on the north side of the building, fronting Robert Speck Pkwy., sheltering on a ledge just below the roof. No sign of the male bird.

Saturday April 3, 1999
Marcel Gahbauer reports:I arrived at the Mississauga Executive Centre around 1:15 pm this afternoon, just in time to see an adult male peregrine fly north past the west side of #1 Robert Speck Parkway. I spent the next 45 minutes walking around all four of the office towers along Robert Speck Parkway, but did not have any more peregrine sightings.

Thursday April 1, 1999
Mark Chojnacki reports:  Last year I was fortunate enough to be able to watch a pair of Peregrine Falcons from my office window all spring and summer at 1 Robert Speck Parkway in the Mississauga Executive Centre (just east of Square One near the junction of Hwy 403 and Hwy 10). My first sighting last year was February 19th. So far this year there was no sign of any Peregrines - until today! I just saw one bird fly past my office window and as I type this it is perched just under the "Mississauga Executive Centre" sign on the northwest side of the building at 2 Robert Speck Parkway (southeast tower of four buildings). Unfortunately, I didn't bring my binoculars with me today to work so I can't give any more specifics on its identity.

Tuesday March 2, 1999
Marcel Gahbauer reports: A call about a dead raptor at 4 Robert Speck Parkway caused us to take a trip to the Mississauga site today. There were of course concerns that the dead bird was one of the local peregrines, but instead it turned out to be an adult male Cooper's Hawk. This in itself was quite a surprise, as Cooper's Hawks remain uncommon in Ontario (especially in winter), and unlike the peregrine are not typically found in urban settings such as this.

The hawk had a broken neck, which was presumably the cause of death, as it was otherwise in perfect condition (at least externally). It was found at the base of #4 Robert Speck Parkway, so in all likelihood it flew into a window with some force, broke its neck, and dropped down to the ground below. It may have done this on its own, perhaps confused by reflections from the windows, or it could have been involved in an altercation with one or more other birds - perhaps some of the many crows which reside in the valley just southeast of the building.

Thursday February 18, 1999
Marcel Gahbauer reports: This morning Mark Nash and I met with Angela Ieraci and Lorraine Hart of Oxford Properties, managers of the office towers at #1 through #4 Robert Speck Parkway. They told us that while there have been no sightings of the local peregrines during the winter, many of the office residents became quite interested in their special winged visitors last summer, and are eagerly awaiting their return this year.

Mark and I inspected the roofs of #1 and #2 Robert Speck Parkway. Both buildings have exposed gravel roofs, where the peregrines could conceivably nest. However, the recessed ledges around the maintenance level of #1 Robert Speck Parkway are likely to be more appealing because they offer some shelter. The distribution of remains also supports this theory - along the southwest and southeast ledges there were several starling and pigeon parts which were obviously remnants of earlier meals. However, we did not find and carcasses on the northwest or northeast ledges, nor on the roof of either building.

All we can do now is wait and see whether the birds return in 1999. The setting is about as perfect as one could ask for an urban peregrine - tall buildings, well spaced, with a sheltered nesting ledge and plenty of food - not only the usual pigeons, starlings, and sparrows, but also other songbirds from the creek valley running east of #1 and #2 Robert Speck Parkway. This is a territory that surely will be claimed by peregrines sooner or later.
