We have local wildlife today: photos of nesting peregrine falcons, which are not rare in Chicago. The contributor is Robie Mason-Gamer, an evolutionist and systematist at the University of Illinois at Chicago. Her notes are indented, and you can enlarge the photos by clicking on them. Her captions are indented.
These pictures were taken a while ago , but a similar scene plays out each year. Peregrine falcons (Falco peregrinus) have been nesting on University Hall, at the University of Illinois at Chicago, since the late 1990s. (Point of reference for readers: this peregrine nest is a 6.3-mile straight-line distance from PCC’s duck pond at the University of Chicago.) After a couple of recent missed seasons due to building repair, the university celebrated the most recent brood of chicks in spring 2021. Each year, people from the Chicago Peregrine Program come by to band the chicks, and in 2010, I had the privilege of watching them up close.
Local peregrine habitat—this is what serves as a cliff around here. The birds nest on the ledge just under the top floor.
Banding Day—I think Mother knew something was up. This bird, Rosie, nested here from 1999 to 2012 and hatched 32 chicks.
There were three babies in 2010, but Rosie’s broods ranged from one to four.
In addition to placing leg bands, members of the Chicago Peregrine Program collected some basic information about the chicks, and took blood samples.
This is the new leg band. Look at the size of that foot!
Still covered with fluff, but with adult-like feathers starting to come in.
The male was there as well, keeping an eye on things through the narrow windows. Unlike the female, he was in the air the whole time, and I did not get a well-focused picture of him in spite of numerous attempts.
Rosie was understandably agitated the whole time: “Bring back my babies!”

Wonderful, Robie, thanks! You may know that my colleagues at the Evanston Public Library celebrate and support the peregrine falcons nesting on their building. https://www.epl.org/attend/special-events/falcon-cam/
Thanks so much for these wonderful photos!
What a great program. I love seeing those chick and the concerned parents.
Very cool, Robie, thanks for sharing these!
in Bristol, UK, we also have urban falcons in the city centre. And kites in the Avon Gorge on the edge of the city. There is a farmers market in the city centre, and I was mildly surprised that there were no pigeons. Then one week I came unusually early, and found a falconer going from stall to stall with a hooded bird on her fist. I saw a pigeon coming into land, and saw it see the shape of the hawk, and move from the usually rather graceless flight to a mid air take off. Impressed.
Rosie has a very strong stare. I wouldn’t want to get on her bad side.
Beautiful birds, those Peregrine falcons. It’s nice to know they have a safe area to raise their many broods.
I’m surprised no one on the Internet have started to call them, “murder parrots,” considering falcons are more closely related to parrots and passerine birds than Old World birds of prey.
I didn’t know this! I’m going to look it up right now.
It’s just incredible to me that those little puffs of helpless bird are shortly going to become the fastest animal around and a terror to other birds. Thank you for these beautiful photos.
In the pic just under the “…chicks, and took blood samples”, that little gal or guy seems to be looking at the photographer and thinking: “What the hell you gonna do to me this time?” (anthropomorphizing a bit!)
