Identifying Who They Ate

15 July 2026

Peregrine falcons eat birds for a living and leave the remains behind, usually just feathers and bones. Every once in a while they eat a banded bird and if we’re lucky the band remains on the gravel at the Pitt peregrine nest. Can we identify who they ate?

Right now there’s a small blue metal band near the green perch that’s been on the gravel for about a year, disappearing and reappearing at random.

It cannot be read in a closeup but it looks like a homing pigeon band (racing or wedding dove). It’s uncommon for the Pitt peregrines to catch a homing pigeon but I’ve seen it before.

About 15 years ago during a Pitt peregrine banding, Art McMorris pointed out a homing pigeon band that he’d retrieved from the nest. I volunteered to track down the pigeon’s owner. At the time it was pretty difficult. Each pigeon owner affiliates with a pigeon association and each association has its own band listing. You have to decipher the Association Code before you can begin.

I was having a hard time getting anywhere until it dawned on me that the last 10 digits on the band looked like a phone number. So I called it and immediately reached the pigeon owner in northern Indiana.

He told me that the bird was part of a Young Bird race — hatched 3.5 to 4.5 months earlier — that started in southern Indiana. It should have flown north about 200 miles. Instead it flew northeast about 400 miles — twice as far — before it stopped. It apparently had a compass error so it was totally unsuitable for racing. He did not mind that a peregrine ate it.

At the Center for Conservation Biology they monitor peregrines that nest throughout Virginia including at the James River Bridge at Newport News. Bryan Watts tells the story of prey bands found in peregrine nests. It’s interesting to note that Eastern Shore peregrines eat a lot of shorebirds, some of which have flag bands

Next winter when we clean the falconcams we’ll collect the blue band … if we see it and remember to look.

I Still Don’t Wanna Grow Up!

10 July 2026

On Tuesday morning, 7 July, I was chatting with friends at Schenley Plaza when I heard a young peregrine whining for food — a normal sound in early June when young peregrines have just fledged but atypical in July.

I looked up to see the whiner chasing her parents around the Cathedral of Learning. Yes, it was Yellow. She arrived at the nest the previous evening when her parents were not around.

Right now the Pitt peregrines are mostly off camera but there are occasional moments of excitement. Ecco and Carla bow at the nest. Yellow pops in unexpectedly.

Check the snapshots to see if someone’s on camera. Tune in to the National Aviary falconcam to find out who it is. The falconcam will stay up through the end of July. Show your support at the National Aviary’s Adopt-A-Bird program.

Meanwhile Yellow still doesn’t want to grow up. How long can this go on? Sooner or later she has to leave home.

Red is On His Way to Rehab

3 July 2026

In early June I routinely saw only one juvenile peregrine at the Cathedral of Learning. This was puzzling because young peregrines usually hang out at home for a couple of weeks, chasing their parents and playing in the sky with their siblings. Where were the other three? Puzzle solved for one of them: “Red” was rescued in early June and is on his way to rehab.

On Tuesday morning 9 June, the young male peregrine “Red” (Black/Green 09/Z) was found bleeding and stunned at 4400 Forbes Avenue near Carnegie Museum. He was admitted to Humane Animal Rescue of Pittsburgh’s Wildlife Center (HARP) in Verona at 7:00am where the team treated his wounds and evaluated his condition.

Red must have hit something really hard head first because his head was bleeding and he had a concussion. Katie Kefalos, Director of Wildlife Rehabilitation, also told me his lead tests came back positive. He was treated for lead and his levels returned to normal.

HARP was hopeful that Red could rejoin his family soon for hunting school but on 18 June, wounds healed and lead-free, he flunked his flight test. He was too wobbly to go home. (Concussions can do that.)

Yesterday, 2 July, Red had another flight test but his skills were still not where they should be for him to learn to hunt. Meanwhile his parents, Carla and Ecco, have moved on from hunting school to “it’s time to leave home, kids.”

At this point Red needs to gain strength and balance and learn to hunt so he can become an independent peregrine. HARP has arranged for Red to be transported to Tamarack Wildlife Center whose rehab facility is equipped to help Red through the next steps.

You might also consider giving a boost to Tamarack Wildlife Center for their upcoming work with Red.

Red doesn’t know it, but he thanks you.

Is She Going to Interrupt Us? No.

A flurry of peregrines. But who? 30 June 2026, 4:51pm (photos from the snapshot camera)

1 July 2026

This morning when I pulled motion detection photos of the Pitt peregrine nest I found three in a row that didn’t make sense. #1 Ecco on green perch, #2 a flurry of peregrine wings, #3 juvenile peregrine Yellow on the green perch.

Maybe photo #2 was Ecco leaving when Yellow burst in, but there were too many wings in that flurry. Who was it? The video tells the tale.

Ecco and Carla were bowing at the nest to strengthen their pair bond. Heaven knows they have a lot to talk about since two of their kids, Yellow and Green, refuse to leave home.

While they’re bowing we hear a whining juvenile in the background. Carla looks up.

“Is she going to interrupt us? No.” (hah!)

Yellow stayed for 45 minutes but her parents wouldn’t come back until she was gone.

You’re Supposed to Feed Me!

28 June 2026

On Friday one of this year’s juvenile peregrines burst into the Cathedral of Learning nest and complained loudly that her parents should feed her “Right Now!” though she’s old enough to hunt on her own.

Ecco was in the nestbox, about to bow — maybe Carla was going to join him? — but we’ll never know because “Green” was so demanding that she chased Ecco away.

Green complained bitterly, “You’re supposed to feed me!” But neither parent responded.

Just like Yellow’s behavior on 23 June, Green was acting half her age. However, unlike Yellow she did not stay at the nest for several hours. She left after seven minutes.

This video shows six of those seven minutes. (I skipped the one minute when she was so far off camera that only her toenails were showing.) Whining. Whining. Whining.

With one or more demanding “kids” back at the Cathedral of Learning, Ecco and Carla stayed away from the nest yesterday. They’re avoiding their soon-to-be-independent offspring so the “kids” figure out it’s time to grow up and leave home.

Read about when, where and how the young disperse in this Peregrine FAQ: Where do young peregrines go when they leave home?

I Don’t Want To Grow Up!

24 June 2026

This morning the motion detection photos from the Cathedral of Learning showed a juvenile peregrine near the snapshot camera. Who is this?

Day-In-A-Minute video reveals it’s “Yellow.” She spent at least half the day loafing at the nest and when her parent(s) came near she begged loudly. They didn’t feed her. Instead they avoided the nest until she was gone. Here’s the 8:30am to 5:00pm timelapse.

In the 10 o’clock hour Yellow slept, begged angrily, and played with desiccated bits of bone and feathers left over from last month’s meals. She’s acting half her age (she was 59 days old on 23 June. 30 days is pre-fledge).

Yellow is staying very close to home. Granted, she had a traumatic experience on her first flight away from the Cathedral of Learning when she was attacked by four fish crows, but she can’t be a real peregrine if she lets those fears stop her.

“I don’t want to grow up!”

Her parents, Carla and Ecco, know she has to, so they’re acting accordingly.

Peregrines Surprise Me: Success at 2 Bridges!

23 June 2026

Halfway into the 2026 Peregrine Season I thought our region would have lower than usual nesting success because we had fewer active sites than last year. But peregrines always surprise me.

This month observers found fledglings at two bridges that weren’t on the list: 62nd Street Bridge and the Rt. 40 Bridge at West Brownsville. This adds two nests and 4 young to our regional total. Woo hoo!

62nd Street Bridge:

Things have been happening fast at the 62nd Street Bridge. After years without a known nest, Matt Jacob found a pair of peregrines carrying food there. Then Jeff Cieslak and Adam Knoerzer discovered they are “Dave” and “Libby” from the failed nest at the East Liberty Presbyterian Church. On 19 June Anne Marie Bosnyak saw a fledgling. On 20 June Jeff Cieslak photographed the family, below.

Rt 40 Bridge, West Brownsville:

Earlier this spring David Argent and Fred Kachmarik both visited the Rt 40 Bridge in West Brownsville and found only one peregrine and no sign of nesting. I assumed (incorrectly) that there was no nest.

On 16 June Regina King messaged me that she saw juvenile peregrines at the bridge so I notified David and Fred, and Fred spread the word to John Flannigan. All three of them visited the bridge last week. There are 3 young peregrines ready to fly.

David Argent visited on 18 June and saw one adult + 2 juvies:

Fred Kachmarik and John Flannigan visited on 19 June and saw 1 adult + 3 juvies.

And they heard begging.


With these two nests, our region is now up to 20 young peregrines produced in southwestern Pennsylvania this spring. Success!

14 June 2026, All Peregrines All The Time

My last update was only six days ago, 7 June, but so much is going on! I have news from six sites.

Site List and latest activity, a regional summary. (Yellow = nest is/was active in 2026, includes one failed nest. Boldface dates are May & June 2026.)

Activity in the region:

Cathedral of Learning, Univ of Pittsburgh:

All four of Carla and Ecco’s youngsters have fledged and are now hard to find until they nag for food. Their parents look for places to avoid the “kids.” The nest is usually the safe zone until …

Yesterday Ecco and Carla bowed at the nest and Carla sunbathed. (Spots on the camera cover are from recent rainstorms.)

But one of the “kids” — Blue — burst onto nest at 10:18am to shout at Ecco.

The streaming app was choppy without audio when this happened but you get the idea. Yes, it was Blue.

Downtown Pittsburgh, 3rd Avenue:

Yesterday, 13 June, I stopped by the Third Ave nest and found a chick preening at the ledge opening (photos at top and below).

Terzo was snoozing above.

Lori Maggio knows there are at least two chicks in the nest and on 11 June she was able to see the younger one from the Smithfield Street Bridge. This one appears to be a week+ younger than the other. Yesterday it was probably still not old enough to come to the ledge edge.

These two will fledge at least a week apart; there will be many opportunities to photograph them in June.

Sewickley Bridge, Ohio River:

All four youngsters have fledged, though Jeff Cieslak has seen only two of them. On 10 June both parents were present while a juvie stretched its wings nearby.

62nd Street Bridge, Allegheny River:

As mentioned yesterday, Jeff Cieslak and Adam Knoerzer have figured out that the peregrine pair at the 62nd Street Bridge is the couple whose nest blew away at East Liberty Presbyterian Church in late March. See how they figured it out at 62nd Street Peregrines Came from East Liberty.

Tarentum Bridge, Allegheny River:

Yesterday Dave Brooke saw five out of six Tarentum peregrines. On 11 June Dan Wyrostek saw three chicks lounging and flapping.

The “flapper” joined the “loungers.”

Westinghouse Bridge, Turtle Creek:

Dana Nesiti confirms that both juvies have fledged and they are still hanging out with their parents.

On 8 June one of the youngsters was eating at the catwalk when his mother snatched a bite of food. No problem. There’s enough to go around.

The Status Table …

… at the top is a screenshot of the table taken on 14 June 2026. Here’s the up-to-date table if you’re reading this many months later.

62nd Street Peregrines Came from East Liberty

13 June 2026

In 2024 and 2025 a pair of peregrines nested successfully at East Liberty Presbyterian’s church steeple where they fledged a total of four young. Nest monitor Adam Knoerzer named them “Libby” and “Dave.”

This March they were on their way to another successful year when a terrific wind storm blew away the sticks that supported the nesting zone. Here’s what it looked like before it disappeared. See more at East Liberty Peregrines’ Nest is Gone.

That was in late March, egg laying season, so Libby had to find a place to nest very quickly. Together the pair looked around for available sites and came up with a plan. They nested at the 62nd Street Bridge.

We didn’t know there were peregrines at 62nd Street until Matt Jacob shared his June 4-5 photos. I wrote about them on 7 June: New Pair Found at 62nd Street. At the end of that article I wondered if this pair had come from East Liberty.

On 11 June Jeff Cieslak visited the bridge and produced the side-by-side photo shown at top.

As Kate StJohn reported last week , a pair of peregrines has appeared at the 62nd Street Bridge. Today, I went to see them, and one was under the bridge on the catwalk not far from Etna. We waited about 45 minutes to see if anything would happen, and at about minute 44 something did. Based on size, the image [at top] shows the female (L) and male (R). The male was actually on the far side of the bridge, but I scaled his image to show the difference.

— description on Facebook at Our Daily Bird by Jeff Cieslak

Adam Knoerzer sent Jeff his photos of Libby and Dave. Jeff put them all together and their face and head features match. Ta Dah! This pair is Libby and Dave.

Libby (left) and Dave (right) peregrines at 62nd Street Bridge, 11 June 2026 (large photos by Jeff Cieslak, inset photos by Adam Knoerzer)

At 62nd Street Libby’s clutch is later than it would have been at the East Liberty because she had to start over. It will be a while — perhaps early July — before we know if they are successful.

This discovery also indicates …

If East Liberty Presbyterian’s steeple (ELPC) has a proper nesting zone, it is a preferable nest site to the 62nd Street Bridge. Peregrines very rarely use the 62nd Street Bridge. This is only the fourth time since monitoring began in 2007.

And yes, it’s possible to identify individual peregrine falcons using photographs. Chad+Chris Saladin have been doing this for years. That’s how they are able to name and re-identify peregrines at various sites in Ohio. See their work at C&C’s Ohio Peregrine Page on Facebook.

On the First Day of Flight

12 June 2026

What’s it like to fly — and land — for the first time? While our young peregrines are fledging, so are those at the University of Leeds, UK where @LeedsBirder records their activities with his scope and iPhone.

On 9 June he captured slow motion of a young peregrine (banded ZBJ) flying and landing in the wind on his first day of flight.

Learning to fly is difficult in gusty winds! Not bad for his first day out in the big wide world. @UoLperegrine ZBJ filmed in slow motion at the University of Leeds today. @BBCPaulMurphy @BBCSpringwatch @BBCLookNorth https://t.co/9rzIlFG2Tg pic.twitter.com/8rIRoNCjqm— Leeds Birder (@leedsbirder) June 9, 2026
