Confirmation that the female peregrine is showing progress with nesting, as of April, 5'th we were able to see one egg and as of April 12'th we have 3 eggs and the female has started to incubate. Remember, in this peregrine pair it is the female that has the adult plumage the male was born in 2004 and has his first year brown streaking plumage. We haven't seen much of either peregrine lately, I was worried for a few days - however yesterday (Tuesday) I witnessed Horus (immature male) doing exactly what he should be doing. Horus was spotted bringing in food and watching over the nest as the female stretched her wings with a couple of buzzes around the county building. This is a critical time for our peregrine pair and what ever observations you make, please e-mail them to me. Remember the pair has settled into the NE corner of the county building - that would be the corner that faces the river and the courthouse. She is tucked 2 feet deep into a cement ledge - you cannot see her from the ground but the ledge is a cement scroll ledge just below the green ledge, she pops up from time to time looking for her guy. Horus tends to hang out on the air conditioner vent on the E face of the building slightly above and south of the ledge, I bet he can see her from there - what a great spot. He has also been spotted chasing a kestrel away from the area.

Need observations: I'm hoping to have a couple of volunteers spend a couple of hours each week documenting our peregrine particulars? We need to document IF Horus brings food and when, and IF Horus starts to perform nest relief? Also, it would be GREAT to figure out who the female is - we need the federal numbers off the aluminum band on her right leg (good luck that is really tough). I have the colorband information: Horus has a black over green band on his left leg - black=898989 and green=PPP. Unknown Female has a black over green band on her left leg - black=sideways capital (I's); HHH and green=sideways 444.

Well that is the update, and thank you for keeping a watch on our peregrine pair.

To All Concerned,

The Sunrise Legacy has Sadly Ended!

I just wanted to let you know that I found Sunrise on Monday, May 9'th 2005 at the Whittier, she was in the SW (back) portion of the building on her back with her head tucked toward her left wing (in a balcony). I suspected that the female I was watching was not Sunrise last week when Ernie Kafcas and I got up-close-and-personal with both peregrines (Male=Allegro, and Female=thought to be Sunrise, but is actually Mariam a rehab bird released in Dearborn) while manipulating the nest balcony. Then Judy told me to go looking for Sunrise, because she knew without a doubt that if Mariam came into the Whittier - Sunrise would have defended it to death. Well, unfortunately she did. You may find this interesting however, when I discovered the carcass and reached down to collect it - Allegro was on me in a heartbeat. He passed by the window several times and was calling. I have no idea, but it almost seemed as if Allegro knew that Sunrise was in that balcony? Well, if he did - he defended her one last time.

I have collected her body, hopefully it is in good enough condition to taxidermy.

On a more positive note, Mariam is doing fine (eating pheasant these days) and she is starting to show nesting behavior (she is trying to choose between the north or south side of the balcony that we modified, she is making depressions in both spots). Hope she will re-clutch - her first attempt was foiled due to that harsh weekend we had back in April (23-24'th).


May 10, 2005

Hello Everyone,

Well, we are past our due date for the Mt. Clemens nest. Don't worry, sometimes when their is cold weather it may set back development a couple of days. I'm checking on the nest twice per day now and still no sign of hatching. I will keep you all informed, however I will be going out of town for this weekend (so my luck all the fun will happen then). Don't worry, I've planned ahead and have recently installed a surveillance camera - I've been able to tape the nest from sun-up to sun-down. When something other then 'Her sitting on the eggs' happens I will be sure to share that portion of the video with you as well. Horus (male) is doing a GREAT job keeping her fed, lately he has been preying on Baltimore Orioles and Brown Thrashers (I've found a number of heads on the cement below). Horus is also doing a great job defending the nest against the vultures, however the female is more aggressive and she actually is 'hitting' the vultures in flight "poof-lots-of-feathers-flying" One vulture tried to perch on the nesting ledge and she was furious! Well, that's all folks. I'll try to send an attached photo, but lately it hasn't been going through.

Thanks for keeping a good watch on our Mt. Clemens Peregrines,


May 11, 2005

Hello Everyone,

Update on the Fisher Building Pair: 4 chicks, hatched over the weekend into Monday. "Alpha" has been confirmed as the female, still assuming "hunie" Chicks cannot thermal regulate yet, so please do not disturb. We will want to coordinate banding within the next two weeks and then they will be moved to the hacking box for everyone to see. Go to this website, I found a person who has been taking professional pictures of the nesting process - this was not smiled upon, however the pics are absolutely priceless, since the disturbance has already happened we mind as well enjoy the pics. Also, a volunteer has reported food coming into the nest area!

Update on Mt. Clemens Pair: Still waiting, on eggs (3 of them). Their is some good news, I have been video taping with a surveillance camera and I finally determined if Horus (male) was performing nest relief........YES he is!!! And he is doing a great job at it also, this makes me feel more confident that the eggs will hatch. I taped it, and believe me when I say if you were watching up to the nest and blinked you would have missed the exchange. Female calls and leaves nest and Horus comes in and starts to incubate the eggs = this takes 16 seconds! He stayed for 1 hour and 38 minutes. Nice Work Horus, I apologize for the jokes about him being a possible "dead beat dad" and her being a "single parent".

Update on Monroe: Still waiting, on eggs (have not determined number). I will go to the Monroe plant tomorrow and check things out. Female is NOT Monroe (still working on the band numbers), Male is definitely Leopold (and he incubates more than she does).

Update on Whittier: Not re-nesting yet, but behavior looks promising. We lost the first nest during that snow storm in late April. Allegro and Mariam are the pair, not Sunrise. Sunrise was found dead in a balcony earlier this week....the end of the Sunrise Soap. Interesting that when I tried to collect her body, Allegro was on me in a heartbeat....he defended her one last time, sad day.

Update on Book/Cadillac: No news, can't find any sign of peregrines. If you are in the downtown area PLEASE look up and let me know if you see something.

Well, I'm off to my Wedding Shower in Texas. Hope you all enjoyed the update, and keep watching out for Peregrine Particulars!

Peregrine Update!

The Fisher peregrine chicks were very active today, I set me scope on the marble dome approximately one block from the building and zoom in on the nest site (this leaves me about one inch of space between dome and building and I wait patiently to see movement). Well today was fun, the chicks were walking around and feeding. We will potentially band around Memorial day weekend, I still have not determined an actual date with the boss.

GOOD NEWS AT MOUNT CLEMENS - we have babies!!!! Yup, two have hatched (probably over the weekend while I was in Texas). I was able to freeze a shot from the video tape and I would like to send it to everyone, the chicks are small but you can certainly tell they are under mom. Remember, the chicks cannot thermal regulate for at least 15 days - it will be at least 3 weeks before you start to see young peeking out of the balcony.

Take care everyone, I'll keep you posted.


And now here's a note from Judy Yerkey, our Peregrine Coordinator Emeritus...

May 23, 2005

Didja know that the male that is nesting in Mt. Clemens is Horus? Horus is the son of Bandit (nesting in Akron, OH with Chesapeake). Bandit is the son of Pop, who was the "Patriarch" (he and Judy were the first pair to nest naturally in Detroit History - and 1,st in 37 years in the L. P.). We have a "grandson" nesting here in S'E Michigan (another 1'st in our history)!

How cool is that?

Fisher Building Site: Both Male and Female are busy, busy, busy bringing in food for their young (I saw the Male today grab a Pigeon, pluck it clean and then drop it in). Incubation isn't occurring as much now, the chicks are approximately 16 days old and Mom and Dad are seen at their regular guard post across the street on the GM building. I've had ample time to watch the chick from my usual post (one block away), but I am yet to determine an actual number: At most I can confirm two chicks, but we would suspect three due to the picture that was taken the day they were born (if we have four, that would be a surprise because the fourth chick really didn't look as healthy or strong when the photo was taken). We prepared the box for moving the chicks - this will happen on June 1'st. After this date you will be able to see the chicks quite regularly because they will be in the box directly above the Fisher building front doorway. I will keep you posted. The female is definitely 'Alpha' (black over green with a 4 on the black and a sideways A on the green). The male is still unknown.

Mount Clemens Site: The rainfall we had the other day soaked our female on the nest, she looked absolutely miserable - but good job mom, cuz the young chick was safely tucked underneath her downy feathers and dry and warm. We only have one chick - I can say for certain that one egg never hatched and the adults have since removed it from the nest area (sometimes they wait a bit after the due date to see, but eventually the egg starts to rot and then the adults know to get rid of it - otherwise it could harm the health of the nest and the young). The adults are known to eat the egg shell for calcium or to simply fly away from the nest site and drop it. I have no idea as to if the other egg hatched or not? I was on vacation when this happened, but I most likely have it on video tape and will review this at a later date. GOOD NEWS, we will be banding the chick on June 1'st in the afternoon (I'm still debating on a name for our "First Ever Chick Born in Macomb County" - if you have something clever send it my way).

Monroe site: One chick confirmed, I watched baby food being brought in and would suspect all chicks to poke out and start to feed - only one did, so I am assuming we only have one on the nest (But one is better than none, right?). This little chick is FULL of adventure, he/she is only 16 days old at most and is already walking the ENTIRE I-beam without problems (I wouldn't be surprised if he/she eventually jumps - make sure I'm called if/when this happens). For those of you that are reading this and have no idea as to how the Monroe site is set-up, don't worry we have a Huge net under the nesting area so if he/she jumps it will basically fall into a net and wait for the rescue rehabilitator to place him/her back into the nest area!

Whittier Site: I checked last week and no signs of re-clutch, it is getting late in the season and I doubt we will have a successful nest this year. Mariam is still accepting food from Allegro, so the pair bond is strong and they are both seen at the nest balcony often.

Grand Haven: I heard from Ernie Kafcas that 3 chicks (25 days old) were successfully banded at the Grand Haven site just a couple of days ago (I guess their are 4 pairs nesting on the west side of the state, WOW that's GREAT).

Well that's all for now folks,


May 28, 2005

Well, I finally found the peregrine pair at the SBC building. They have two chicks, male and female - the male is older than the female by a few days he is very adventurous and has been seen running with wings up along the edge of the ledge. The female is younger, and chunkier, she has not yet hopped up to the edge of the ledge - she is running with wings up in the balcony a bit safer. Both parents are on guard, the female is definitely Sara (1998 Toledo Ohio bird). The Male has a black over green band with an S and idunno? With this partial band it could be (Gregory: 1999, Jackson State Prison Chicago Illinois bird) or (Klutz: 1999 DTE Monroe bird). I'm not too sure, I'll keep you updated.

Two more Peregrines - this is good news!


June 2, 2005

Quick update, pictures to follow at a later date:

Successful banding today at the Fisher building; 4 CHICKS, all banded as females, Girl Scouts named them all (Pearl, Patch, Morgan, Scout). No problems. Mom was seen entering into the new nest site 20 minutes later, getting out was a bit tricky (the young chicks were pulling her back in).

Successful banding today at the Mt. Clemens County Building; 1 CHICK, banded as a female, Commissioner Chair White named her (Alexa) after Alexander Macomb (founder of Macomb county). No problems. Mom was seen perched back on the nest ledge within 35 minutes.

All is well,


June 2, 2005

Hello Everyone,

Thanks to Per Verdonk, a Compuware employee at the New Center building, we are able to enjoy the entire banding event through pictures. Per is an avid wildlife photographer and has agreed to share his pictures with those that have been following the Peregrines in SE Michigan, especially the Fisher Birds. Now, I still havn't figured out the father yet - but mom is definitely Alpha (the step-mother from last year who came in and started feeding the chicks). We banded 4 chicks, all banded as females.

Enjoy the pics, I will be posting more information/pics/and even a video clip when I return from my honeymoon. Please keep a good watch on the Peregrines while I am away this weekend and next week.

Go to this web site (and don't forget to look at the second index also, most of the first index is older pics that you have probably already seen).

Second (Newer) Index Index: Falcons/index2.htm

First (Older) Index: Falcons/index.htm

I appreciate all your assistance and support over the past few months, this job has literally brought so much joy to my life...I look forward to my return and awaiting the first flights of our new Fisher gals (Pearl, Morgan, Patch, and Scout...all named by the Girl Scouts of Detroit).


June 17, 2005

Mount Clemens Chick Update! Alexa is doing GREAT, she is getting so big, has most of her immature feathers and just little patches of feather down sticking out here and there. I suspect that in the next 5-7 days we will be in another critical stage for our falcon, she will attempt to get up on the ledge like mom and dad (the ledge is wide enough where I do not suspect that she will fall). However, a large thermal could catch her wings while stretching and cause a premature flight (more like she will glide down,down,down safely....if its not in Gratiot of course). The problem with this glide is that she will not be able to fly UP yet, her pectoral muscles will need at least an additional week to develop.

Cool sighting by Julie Champion, the Peregrines have been feeding Alexa Yellow-billed Cuckoos - Interesting choice!

Fisher Chicks Update! I have already had to rescue two of the four chicks from the fisher building, last night instead of watching the Pistons game I was running down Grand Blvd with a towel trying to capture a feisty young female. Both chicks are fine, they are with Dave Hogan (Peregrine rehab specialist in Monroe). The reason why we keep them at the rehab place is that he is able to feed them ample quail until they are ready to fly UPwards. When we release them into the box next Thursday the idea is for the young one to immediately fly OUT of the box, but instead of flying just down to the ground it will be capable of flying up to a platform (like a roof top or something). We must make sure that both parents are watching the box when we do this, the parents will watch then follow the young bird to its landing site - they will continue to care for the bird at this site and start instruction as to flying and finding food. The chicks do this naturally at this time in their life....usually the chicks are higher up on a nest site and when the first couple sets of glides take place the chicks find another ledge to land onto, in our case at the Fisher building the nest is unusually low therefore the first glide usually results in hitting the floor (it is then when the bird realizes that it cannot go UP).

Cool sighting at the Fisher building today, mom and dad drove away an Osprey!!! Lots of stoops at the Osprey until it finally gave up and left the area.

Monroe Chick Update! Mom and dad are still protecting their one chick, looks great! Still pretty young, about the same age as our County bird.

Peregrine Lady Update! Well, I'm married! I am now Kariann Anderson! The wedding was beautiful and the honeymoon in Maine was relaxing and fun. I was happy to come back to see how big my baby peregrines have become, thank you everyone for watching over the nests while I was gone.


June 18, 2005

WELL THE VERDICT IS IN: WE NOW KNOW WHO OUR MOM RAISING YOUNG ALEXA! Turns out our mom (*H/*4) is only 2 years old and she has traveled from the University of Pittsburgh's Cathedral of Learning! Unfortunately, our Pennsylvania fledged birds do not have names assigned to them (so I suppose she will be known as Alexa's mom).

Our female falcon's mother is Dorothy 5/*A (hatched and fledged 1999 Firstar Center, Milwaukee, WI), the daughter of the Midwest's 2nd most productive female falcon Sibella 20V (1988-2003) and her mate Bill 74T (1990-2001). The asterisk is used for records only and indicates the character is tipped on its' side!

Our female falcon's father is Erie *T/W (hatched and fledged 1998 from the Rhodes State Office Tower, Columbus, OH), the son of the patriarch of Columbus' falcons - Bandit (unbanded male) and his first mate Aurora red 4R0 (from Aurora, Canada).


June 23, 2005

Hello Everyone,

The release of the two rehab falcon chicks was successful, we released them on top of the Old GM building across from the Fisher building. They walked away from their 'pet-carriers' and immediately started to exercise their wings and running on the roof together, as they approached the ledge it took the two awhile but both managed the 3 foot hop up and perched. This is when I thought to myself, wow these two falcons have never been this high before and have never felt such strong winds it didn't surprise me when they didn't take flight just yet. It only took about 3 minutes until the sibling (the one that has been flying around with ma and pa for the past week) sighted them and flew over to check things out, as the sibling circled dad joined in and shortly after so did mom. As the three circled the chicks the female chick was flapping her wings and being extremely vocal, the male chick was still trying to figure out perching. The family has been re-united! I had to leave to go teach a class, so I'm returning today to see if any flights have taken place.

We have three chicks left at the Fisher building, the oldest chick P74 (the one that was missing) was found dead the other day. She hit the 14'th floor window and broke her neck.

If you would like to see pictures of the release event go to Per Verdonk's website and start on page 2 and finish up on page 3. The link below will take you directly to page 2. Falcons/index2.htm


June 23, 2005

ATTN ATTN ATTN: BABY ALEXA IS OUT ON THE LEDGE!!!! If you have binoculars go stand near the courthouse on your lunch break and see her, remember to check out the Macomb County web site and she her most recent picture (she doesn't look like ma and pa). Alexa will have lots of different shades of brown feathering and will probably look a bit unstable in comparison to her parents. No flights yet, but this is the next step...give her a couple of days.


June 24, 2005


The University of Detroit Mercy: A Catholic university founded by the Society of Jesus (the Jesuits) and the Religious Sisters of Mercy. The old University of Detroit and Mercy College of Detroit consolidated in 1990 to become one institution - the University of Detroit Mercy.

Adult Male and Adult Female (have not yet determined banding) successfully raised three young peregrine (45+ days old now) in the Clock Tower in the center of campus across from the Chemistry Department. All three young Peregrines have been seen flying strong from rooftop to rooftop and back up to the tower. I will spend more time learning the Peregrine Particulars, but I thought you would be interested in knowing that we have a NEW nest site.

The Peregrine Patrollers have already named the three young chicks (although we cannot band them, it is easy to tell them apart from one another). We have IGGY - Saint Ignatius Loyola was the founder (in the 1600s) of the the order of priests that became known as the Jesuits. We have CATIE - Catherine McAuley founded the religious sisters of Mercy in the 1800s. And we have MERCY - Mercy is named after the University.

I'll keep you updated: three peregrine were spotted playing in a puddle on the sub-roof of the Fisher building today (P75; Pearl.....P73; Patch......and P72; Scout). Unfortunately, as you all know P74 is dead (her name was Morgan).

Alexa (P71) is out on her ledge now; it is the 11th floor ledge that faces the river and remember she is in the NE corner of the county building. If you go across gratiot toward the river and stand on the grass you should be able to see her, she spends ample time lying down on the ledge though so it may look like a gray blob (if you go to the police parking lot across the river you can see her GREAT).


June 25, 2005

Morning All,

I'm sorry to report this sad news to everyone who cares so very much - Alexa was found dead this morning at 8:00am on Main Street. I've received reports that our Alexa did in fact have her moment of glory and took flight last night (Friday) around 8:00pm, as she flew toward the administration building, rapid awkward flapping rendered her to loose altitude, a witness saw her parents Horus and Hathor swoop underneath with calls of encouragement and she landed on the rooftop near the American flag successfully. Alexa was then spotted making 10 to 15 flights around the administration building, which would have suggested that she was indeed a strong flyer. They all rested for a short period then all three were spotted flying off the administration building south (8:30 pm).

What happened between 8:30 pm and 7:00 am? As I investigated the area, I concluded that Alexa was simply exhausted from her first flight and hopped down between two buildings onto a guard rail (2 ft. above the ground) and perched for the night (this was evident from the number of droppings found under the rail). At 7:00 am a witness spotted her on this rail and was startled by her, this witness slowly retreated from around the corner and notified those working that morning at the county building. Unfortunately, during the time that Alexa was spotted on the rail and the time it took to notify proper authorities, (Alexa tried to fly off and with her large, heavy body she needs much distance at low altitude to take proper flight and she took flight west toward Main street), Alexa was hit by a vehicle. I was called this morning after Alexa was dead...

I have rescued Peregrines in this same situation before, however this time I wasn't notified as to her needing my aide. My volunteer wanted me to let you know the story of her flight and the dedication of the parents in helping her succeed. We look forward to next years attempt....Our Peregrines have a strong pair bond (Horus; Greek for 'He who watches from above' and Hathor; Greek for 'Keeper of Horus') and next year we will most likely have 3 or 4 young Peregrine to watch out for. Thank you for all your help and concern for this majestic bird,


July 5, 2005

This isn't your typical Peregrine Update, I have been monitoring another event on the County Building (SW corner: opposite corner of the Peregrine nest) and thought you may be interested in seeing the sequence of pictures I've collected. We have a pair of 'Pigeons' nesting on the county building! I know what your thinking, Oooo Big Surprise Kari! But what interests me about this event is that 'Horus' and 'Hathor' have been perching on the ledge just 2 feet above where the pigeons are nesting. I have literally seen Horus looking down at the young pigeons and yet the two have survived over a month. I first noticed the eggs on June 2'nd and have periodically peeked in, I noticed young pigeons on June 20'th, and today July 5'th the pigeons look almost full grown. Very Interesting! Also, I thought you may want to see what a pigeon looks like as a chick - this is a first for me, and I would have never guessed that the yellow puff ball with a huge dark beak was going to develop into a pigeon.

Enjoy the photos. I have three: egg stage, chick stage, and juvenile stage.

July 21, 2005

Just wanted to let y'all know that we have Peregrines nesting on the Blue Water Bridge! MDOT noticed two adult peregrines hangin' out under the old bridge over the water closer to the US side and they decided to construct a cedar Peregrine nesting box. Two weeks after they built the box, the Peregrines started nesting - gives whole new meaning to "If you build it they will come."

Although we have not yet identified the parents, we do know that they are indeed banded - and most likely at least one was born to a nest box (otherwise we suspect that the pair would have chosen one of the other million structures possible for nesting). The pair had four young - two of which ended up in rehab with Dave Hogan (last week we picked them up from the main pier at the Thomas Edison Park, just under the new bridge).

The two females (Swoop and Bridgette) are large and strong, we released them today back onto a platform of the new bridge. The two sisters walked out of their cage and began eating the dead quail Dave left them - once the quail was gone the more adventurous 'Swoop' decided to hop onto the pet carrier and the vocalizations started between both sisters and mom (whom watched the entire event only a few sections of the bridge away). Swoop flew first, strong and was able to perch on the cable at the very top of the bridge - when she flew mom joined her with vocalizations of encouragement. Bridgette on the other hand decided, when mom returned to her watch post, to use the stairs - yup she hopped stair by stair to mom and joined her on the beam. Mom left and after some vocalizations Bridgette also flew. Not as strong a flyer, but she did well. We witnessed several flights and before I left the two sisters had found one another on the old bridge, near the top and were resting. What a wonderful day at the office!

There will be a write-up in the Port Huron Herald, I believe they have a website - check out the photos!


Thanks to Barb Baldinger for looking up the link to the Port Huron Herald and providing the link - MG.

Update on Blue Water Bridge Peregrines; I received this report from Dan Miller (Peregrine Patrol in Port Huron). I was on patrol last Saturday (the day of the boat racing start) and could confirm two adults and one juvenile - I sat for nearly 4 hours and NEVER witnessed a flight, not even from the adults (my guess is the boat and helicopter activity had those Peregrines perching on the bridge for safety). Anyway on Monday, Dan confirms all is well:


I went to the bridge on Monday morning from 0800-1000 and saw both adults and both young. They still seem to be lazy young birds. They want to walk along the beams rather than fly. Both young birds did fly but one definitely is a better flyer than the other.

One adult (the female, I believe, with the missing tail feather) has been sitting on the top rail of the north bridge and making short hunting flights. She caught two small birds (swallows or swifts) and headed back to the bridge with one young just screaming after her in hot pursuit. The adult kept the prey like she was making the young fly to her. I think the adult ate that first bird. The second bird captured was plucked and then carried off and the adult stopped on top of the bridge away from the young birds. Again it was like the adult wants the young to fly and come to her. The young are calling often - I imagine begging to be fed.

The young have improved in their flying - at least they can now stop more gracefully. They don't fall off the bridge rails or lose their balance anymore when they come to a stop. The female headed out over the lake and one young followed but soon turned around and went back to the bridge. It's like the young doesn't want to get too far from the bridge structure, maybe a confidence thing. I have seen no hunting attempts by the young birds. I will check again in a couple days and want to see them gain confidence in their flying skills and start to learn to chase prey. I'll let you know what I see.


August 2, 2005

I received report over the weekend that the third Juvenile from the Blue Water Bridge nest was euthanasia at the University of Guelph Veterinarian school of medicine, after several attempts to control multiple seizures.

Here is the whole story: The young bird had been delivered to Salt Haven Wildlife Rehabilitation Education Center on July 12'th by a concerned Canadian citizen (Wayne), who witnessed the birds failed attempt to reach the nesting area from the Canadian side (apparently the bird flew from the shoreline, made it approximately 1/4 of the way to the nest, then lost too much altitude so swung back to glide back down to the ground, but hit a cement pier in the process). Reports from local teenage divers on the Canadian side indicate that the bird had been attempting this for nearly three days. When the young peregrine arrived at Salt Haven, several people were involved in its survival - I received reports that the bird was diagnosed with 'Frounce' which from all my research is similar to a Yeast Infection in the crop, I've learned that raptors can get Frounce from eating a contaminated pigeon. My guess, the reason why the other two juveniles did not have this problem when they were inspected by our vet is that possibly the parents did a food drop to the young juvenile that was stranded on the Canadian side (rendering this bird the only bird to eat the pigeon), or possibly the bird was so hungry it decided to feed upon a dead pigeon. Either way, I suspect this juvenile contracted the frounce after it had been separated from the family unit.

Salt Haven work hard to clear up the frounce, they did so what we thought successfully, and due to the extreme swelling of the crop - the staff had to force feed the bird just to keep it alive. Once the bird bounced back, and the frounce had cleared up - we (the DNR) tried to get the bird over the bridge to Dave Hogan (much red tape involved in transporting a bird over international waters; mainly working with CITES law and regulation). Once we realized that the red-tape was going to take a couple days, we found a rehabilitator in Sarnia (unfortunately the rehabber only had the bird for one day, because the next day she reported the bird as looking lethargic and refusing food).

The bird was transferred to the University of Guelph, diagnosed with still having frounce, treated for frounce, and they were trying to alleviate or soothe the sores in the crop as a result of the frounce - which anyone that can remember a really bad sore throat, eating something isn't the first thing on your mind (it hurts). In the meantime, we were still trying to coordinate a transfer. All came to an end over the weekend, the sister will not rejoin its family unit.

I can't help to think of all the good that came out of this though, our connections with the Canadian side are stronger than ever now - for years to come it is likely that we will have juveniles fledging from under the Blue Water Bridge, and I am confident that "No Bird" in need of our assistance will go undetected. Also, I am thankful for the two sisters that we were able to assist (who did not contract frounce) and are currently being monitored by 'Peregrine Patrol' volunteer Dan Miller of Port Huron (recently retired customs officer for the Blue Water Bridge), Dan says they are getting stronger everyday.

Hello Everyone,

I will be on vacation until September 1'st (going to Alaska). When I return I plan to develop a summary of this seasons Peregrine Falcon Monitoring. I will send you a copy of the report upon completion. If you have any new sightings, please send in your observations. I checked last week and it seems that the University of Detroit Mercy site is the best for viewing juvenile behavior. The pair at the Whittier hotel are still very much defending their balcony so it is likely to see the adults (they didn't produce any young this year). I apologize for not keeping up with my e-mails, Wayne State recently hired me on as a full-time Instructor and with that I received two 'NEW' courses to develop during the Accelerated Summer Session - UGH! I survived though and now I'm off to Alaska to fish for silvers :)

I appreciate all your enthusiasm and genuine concern for the Peregrines; your observations, volunteer monitoring, and e-mails make my job much easier - Thank you!

A quick note from our former Peregrine Coordinator, Judy Yerkey.

Just got the Indiana 2005 update from John Castrale.

Brook (2003) went down to Gary IN Steel Plant and kicked-out his grandfather, Vulcan - (Mom - Monroe's dad) earlier this year! How cool (eh?). I guess it was too late in the season for any nesting - but - stay tuned for 2006!
