If you watch peregrines you know how improbable it is that you will ever see one make its first flight. In 23 years of watching peregrines I’ve seen it once, maybe twice. I have no photographic evidence but I know of two Pittsburgh examples.
So what does it look like when a peregrine chick makes its first flight? Wakefield Cathedral, UK (@WfldPeregrines) has so many cameras on their peregrines that the moment was captured on 17 June.
Peregrine season is wrapping up with confirmation of breeding in one location and a bunch of “pair only” sightings in the Ohio River valley.
East Liberty Presbyterian Church, Pittsburgh:
Adam Knoerzer confirmed one chick at the nest in early June but hadn’t seen any sign of it since the 17th. Then on Monday evening 24 June, Adam was near East Liberty Presbyterian Church and confirmed “Juvie Alive and Well.”
After hearing a lot of noise, I noticed the juvie perched on a low tower on the Penn Ave side and the male dropping some food. We later saw [the juvie] fly back up to the nest.

The Eckert Street peregrines went missing this spring but there are many nest site choices within a mile of that site. Jeff Cieslak tried to find them with no luck but on 13 June Andy Moore (author of Pawpaw: In Search of America’s Forgotten Fruit and the upcoming book Beasts in the East) photographed a pair of peregrines at the Brunot Island Railroad Bridge.
Jeff Cieslak started checking Brunot Island and has seen the pair as recently as Sunday 23 June. Jeff remarked “I’m pretty sure the female from Eckert is there, with a young male.” No evidence of young.
Spruce Run Bridge, Ohio River: This pair is present every time Jeff Cieslak stops by, most recently 23 June. This pair is an adult female with a 1-year-old male. No young at this site.
Monaca-East Rochester Bridge, Ohio River:
On 16 June Tim Johnson saw a pair of peregrines near the Monaca East Rochester Bridge and on 24 June Jeff Cieslak photographed them. There is no evidence of young this year.
West End Bridge, Ohio River: Remember that banded peregrine Jeff Cieslak photographed here on 13 June? Its bands have been traced to Baltimore, Maryland, but it hasn’t been seen since. No peregrines at the West End Bridge.
PEREGRINE SUMMARY FOR SOUTHWEST PA: This is probably the final update for 2024. Many of these sites did not have successful nests.
Yesterday morning when the heat index was 96°F, Carla sunbathed for 20 minutes at the Pitt peregrine nest. Her fanned tail shows us why she was doing it. Not only does sunbathing kill feather lice, it eases the discomfort of molting. Carla is molting her tail feathers two at a time.
Carla began her sunbathing session after she and Ecco bowed briefly over the scrape. She might have stayed longer but her youngster “Blue” showed up. Carla and Ecco are both avoiding their “kids” in an effort to make them independent.

Most of us didn’t see much of the outdoors this week. It was just too hot. Fortunately today is the last day of Pittsburgh’s Excessive Heat Warning. Tomorrow we’ll have rain, thunderstorms and wind, though it will reach 90°F. Certainly hot. Not “Excessive.”
Yesterday while it was 93°F, one of the Pitt peregrine youngsters (“Blue”) tried to beat the heat by resting in the shade at the front of the nest. She opened her wings and gular fluttered (like panting) to cool herself off.
Two days earlier her father, Ecco, was sunbathing at noon! The sun’s heat kills feather lice and forces the live bugs off the bird’s back to places where it’s easier to preen them away. After roasting a bit, Ecco spent time preening in the shade.
Some day soon (I hope!) it will be pleasant enough to take a walk in the sun as I did on 12 June at Aspinwall Riverfront Park. Every time I go there I look for peregrines but have not found any.
The juvies have made a lot of progress since 11 June when Liz Adams took this photo of one of shouting from the 32nd/33rd floor parapet. Such a lazy bird! On its belly demanding room service! It eventually flew away toward Carnegie Museum.
This week both juvies harassed a crow at Bayard and Bellefield and chased their parents around the top of the Cathedral of Learning. By the time I snapped this photo they were out of the frame.
They’ve learned how to hunt at this point but it’s a lot harder than wheedling food from their parents. On Monday they figured out that Ecco hides from them at the nest so they both invaded. Ecco shouted and left immediately. See the slideshow of their antics.

Downtown Pittsburgh:
On Monday morning 10 June PGC’s Patti Barber emailed that a Downtown juvie had been rescued from the ground and placed up high again. This Monday, 17 June, Matthew DiGiacomo heard a juvie peregrine calling overhead and posted this photo of it on Pittsburgh Falconuts Facebook page.
First, I heard the distinctive call. Didn’t take long to spot it soaring above the Forbes Avenue Garage.
East Liberty Presbyterian Church, Pittsburgh: No photos available but Adam Knoerzer wrote yesterday, 18 June:
In E Liberty now — the young one was definitely flapping wings yesterday and exercising, and I can’t see a thing in the nest today. The female is perched much lower than usual today on the eastern face, and I wonder if perhaps the young one tried to fledge and is somewhere on a low roof.
The female is in a decidedly unusual spot for her — and she has some prey in her clutches but isn’t eating it. I did briefly hear vocalizing, but it wasn’t very long or intense.
I guess it’s possible that the chick is lying flat due to the heat or something, but yesterday it was pretty easy to see it anywhere due to its size.

West End Bridge, Ohio River: On 13 June Jeff Cieslak photographed a solo peregrine at the West End Bridge. It is banded Black/Green and appears to be “xC/20”. (The “x” means I can’t read that letter. Jeff digitally flipped the band rightside up.) Did I read the band correctly? Do any of you know this bird?
Rt 40 Bridge, West Brownsville, Monongahela River:
On 1 June five birders visited the Rt 40 Bridge to watch the peregrine family of four. When Fred Kachmarik visited on the 9th and 15th of June the two youngsters were doing well.
There is a 60% mortality rate among peregrines in their first year of life so the loss of a chick is, unfortunately, an expected outcome.
As soon as the breeding season is over adult birds molt to change out their old feathers. During this period many birds look ragged. We’ll see a few bald cardinals and blue jays who’ve molted all their head feathers at once. Peregrines will seem lazy while they molt in July and August. Canada geese won’t be able to fly.
This week at Duck Hollow I noticed that Canada geese are already molting. Their white rumps are showing, which indicates they’ve lost all their flight feathers.
At the end of this month Pitt’s peregrines will be molting too. We might see a peregrine feather on the falconcam.
Ever since both Pitt peregrine youngsters fledged on 2 June, their parents have been moving them toward independence. At first they supplied the juveniles with food just as they did at the nest, but within three days Ecco and Carla began showing and teaching them how to hunt. As the juvies gained hunting skills the adults reduced food deliveries to encourage the “kids” to hunt. Yesterday one of the youngsters missed those easy meals and was so loud that he attracted attention from the upper floors of the Cathedral of Learning. “Bring me food!” he whined, “I don’t want to grow up!”
Here are some video examples of this behavior filmed at other peregrine sites. Juvie peregrines all share this behavior.
“Hmmm. Maybe my parents can’t hear me. I’ll beg louder.”
“Maybe my parents can’t see me. I’ll open my wings.” … “Look! It’s me! I’m hungry!”
“I can see my father over there but he’s not looking at me.” … “Hey! I’m over here. Don’t ignore me!”
Juvenile peregrines are very loud and they can look pathetic.
Don’t be fooled, humans. It’s an act.
p.s. Injured peregrines are silent. They don’t cry or call because they don’t want to attract attention to their vulnerability.
During the breeding season birds try to drive predators away from their nests and young. Though small birds aren’t equipped with sharp beaks and talons, they relentlessly dive bomb raptors to make them leave the area.
In June 2021, Chad+Chris Saladin filmed a pair of blue-gray gnatcatchers (Polioptila caerulea) attacking a recently fledged young peregrine at the Cleveland Zoo. Gnatcatchers are really small so they barely ruffle a peregrine’s feathers.
But the young peregrine was so new to flying that she wanted to stay put for a while. One of the gnatcatchers pecked her head. “Hey!”
Watch the encounter in this video by Chad+Chris Saladin. Chris explains what’s going on to passersby.
You may see chickadees attack blue jays, blue jays attack crows and red-winged blackbirds attack just about anything. This is the time of year when Little attacks Big.
UPDATE on the Pitt Peregrines: Yesterday, 10 June 2024, I was happy to find all four peregrines at the Cathedral of Learning at 12:15pm. Ecco was on camera on the green perch, Carla was on a stone peak at 38NW, one of the juvies was eating on the southwest dining ledge (approx 28th floor) and the other was on a grommet at 25SE. (The adults never perch on the grommets.) The Pitt peregrine juvies have been flying for more than a week now and are learning valuable skills.
Peregrine falcons have been busy this week and so have been their observers. Here’s a quick roundup of peregrine news in Pittsburgh.
Cathedral of Learning, Univ of Pittsburgh: Everyone is flying; the family is doing well.
This week I learned that both Pitt peregrine chicks fledged on Sunday 2 June. At Fledge Watch at 4:30pm there was only one chick on the nestrail so the first one must have flown between 3:30pm & 4:30pm. Then at 7:00pm Jenna Burdette and her husband were at Schenley Plaza when the second one make its first flight. They saw Carla and Ecco accompany the fledgling around the building to its first landing.
On Tuesday 4 June I watched Carla and Ecco demonstrate an aerial prey exchange while a youngster chased them. Carla then tried to entice the juvie to do the prey exchange with her but the youngster was tired of the game. Carla caved in and brought food to the fledgling.
Also on Tuesday 4 June, Carla and Ecco took a “time out” from the kids by perching in inaccessible locations and bowing at the nest.
On Wednesday 5 June Stephanie Hoogendorn on 19th floor saw and heard a juvie begging on the 16th floor patio. The juvie flew off toward Carnegie Museum.
Downtown Pittsburgh:
John English and I visited the Third Avenue peregrine site on Monday 3 June and saw four chicks at the opening and an adult on the gargoyle. The chicks hadn’t flown yet.
On Friday 7 June Debbie Kalbfleisch stopped by Third Avenue and saw 2 young birds. One at the nest and another on the nearby roof. “While I watched, the one on the roof lifted off & down 3rd & over the building where I lost it. Also saw an adult on the bar above the nest earlier.” By now two or three have fledged.
East Liberty Presbyterian Church, Pittsburgh: There’s a chick at the East Liberty Presbyterian nest! Adam Knoerzer photographed it at the nest opening on 5 June.
West End Bridge, Ohio River: On 4 June Jeff Cieslak photographed a peregrine at the West End Bridge (photos at top and below). When he processed the in-flight photo he noticed that the bird is banded. I wonder who it is.
Eckert / McKees Rocks, Ohio River: No photos available but on 4 June Marcie at Don’s Diner saw peregrines at the Ohio River Boulevard Eckert Street Bridge. They were gone by the time Jeff Cieslak could get there. 🙁
Spruce Run Bridge, Ohio River: Also on 4 June Jeff Cieslak saw both peregrines at the Spruce Run Bridge. They are still getting acquainted … loudly!
By 3 June at 11:00am both Pitt peregrine chicks had made their first flight. Here’s how I know …
On Monday morning I walked around the Cathedral of Learning looking for any peregrine anywhere on the building. Youngsters tend to perch in locations the adults don’t use and an adult perched in an unusual place is watching a youngster.
When I saw a peregrine on a favorite perch at 40th floor Northwest, I assumed it was an adult because the location, pictured above, is too challenging for an amateur to land on. Through my scope I confirmed it was a juvenile, probably the male nicknamed Yellow who fledged a day or two ago.
I could not find the second chick, Blue, but I found an adult intently watching the 38 East “patio” roof so it’s a good bet that youngster was over there. My hunch was supported by two “kakking” episodes in which an adult circled the building and shouted at a potential threat at that level. The adults are highly aggressive at this stage.
Around that time Ecco visited the nest for a while, apparently taking a break from babysitting.
The parents chill at the nest because the “kids” won’t return to it unless there’s food. At this point the parents are delivering food to the fledgling wherever he is. Soon the youngsters will gain flight confidence and chase their parents to get the prey. Eventually they will learn to hunt.
The last Fledge Watch is cancelled (would have been 6/4) because the youngsters have left the nestrail. The only way to see them now is to walk around the building looking for them. I know from experience that it’s hard to catch up to a peregrine who can fly.
