Downtown Peregrine Fledge Watch, Third Avenue, June 7, 10, 11, 12 … 11a-1p
During the second week of June — perhaps earlier — the peregrine nestlings on Third Avenue will make their first flight. Because their nest is low they may need our help. In the first 24 hours of flight, fledgling peregrines lack the wing strength to take off from the ground and have to be put up high to start over. The PA Game Commission (PGC) will send an officer to rescue the bird. Call PGC at 724-238-9523.
The #1 purpose of Downtown Fledge Watch is to educate the public so lots of people know to call the Game Commission if they find a downed peregrine. We’d love to believe trained volunteers can find every bird but the reality in Downtown Pittsburgh is that peregrines in trouble are found by people who’ve never seen a peregrine. People often tell building security guards about the birds so I’ve notified nearby Point Park University (site of the rescue porch).
Downtown Peregrine Fledge Watch is a drop-in event to watch the young Downtown peregrines, educate the public about peregrines, and alert the PA Game Commission at 724-238-9523 if a fledgling needs to be rescued from the ground.
Come when you can. Bring binoculars or camera if you have them. Be sure to check the blog for updates in case of weather cancellation.
Where:3rd Avenue between Wood and Smithfield in Downtown Pittsburgh. (click the link for a map) When: On weekdays, Fri June 7, Mon-Wed June 10-12. Time: 11a-1p. Fledge Watch is weather dependent and will be canceled for rain or thunder. Who: I’ll be there (except June 12) with John English of Pittsburgh Falconuts Facebook group. Notes: There is no official Fledge Watch on June 8-9 weekend but John and/or I may be there. On-street parking is free on Sundays.

Yesterday at 30 days old the Pitt peregrine chicks reached an important milestone. They both jumped up to the front perch. It’s their first step off the gravel, the first step toward ledge walking and eventual flight.
Perhaps their parents encouraged them. At lunchtime Hope and Terzo flew circles around the Cathedral of Learning, lazily gliding past the nest and wingtip-flapping like a juvenile peregrine who’s just learned to fly. It looked like they were saying, “Here’s how you do it, kids.”
Just before 6pm the chicks were wound up. One flapped wildly, eyed the perch and up he went. (Notice the red tape on right leg band). He examined the gully for the first time, partially hiding his brother from the camera’s eye.
Then his brother (yellow tape) got into the act, flapped and jumped. Both on the perch! When the novelty wore off they went back to the gravel.
In a week to 10 days these two will start to fly. Before that happens they’ll walk away from the nest and out of the camera view.
When they’re no longer on camera, come down to Fledge Watch to see them in person. I’ll post the Fledge Watch schedule tomorrow for Pitt and Downtown.
Peregrine falcons are such top predators that adults have few enemies but their young are vulnerable. The parents protect them loudly and vigorously. When peregrines are agitated, everyone knows it.
During the nesting season peregrines monitor for threats and chase them away. They escalate their actions to match the threat level — from a visual show of strength, to shouting and swooping, to direct attacks.
Shouting is important. Peregrines intentionally create a ruckus because the noise calls their mate for assistance, warns their young to lay low, and worries their enemies.
Who is the top threat for peregrine falcons that nest in cities? Humans! When we hear them shouting we get worried. Of course, that’s what peregrines want.
The peregrines that nest in Downtown Pittsburgh — Dori and (not confirmed) Louie — have chosen a site on Third Avenue that’s inevitably surrounded by humans. The birds have a comfort zone that narrows as their chicks grow up. A couple of months ago a human on a roof four stories below them was no big deal. At this point it’s too close.
On Monday a roofer (that we humans couldn’t see from the ground) made repairs on a building several stories below the peregrines. He wasn’t a threat to the birds but they decided otherwise. They flew around, they perched and shouted. Lori Maggio’s photos below show them shouting from Lawrence Hall and from the nest opening. This went on as long as the roofer was up there — until quitting time around 3p.
The photos above are silent but here’s a sample of what they sounded like. The Downtown peregrines were so loud that people heard them from indoors 2-3 blocks away (see this comment from Sandi).
So what happened next? The workman finished and left the roof. The peregrines stopped shouting. Dori joined the chicks at the nest and Lori Maggio got a rare photograph of this year’s chicks, as seen from the Smithfield Street Bridge.
In the end, Dori and Louie probably felt victorious since their shouting appears to have chased off the human. Their chicks learned a valuable peregrine falcon lesson: Humans are dangerous. Keep away!
p.s. Using the chicks’ photo, Art McMorris estimates they were 18 days old on Monday, so they hatched on May 2 and will fledge the 2nd week of June. My prediction is they’ll be completely gone from Third Avenue by June 15.
This flowering tree is a native North American but was so rare that few people ever saw it until botanists fell in love with it.
Originally found in small patches from Arkansas to Kentucky and Tennessee, the Kentucky yellowwood’s (Cladrastis kentukea) beautiful flowers, mid-story height, and tolerance for full sun in urban settings makes it the perfect ornamental.
On Sunday in Schenley Park, our group was awed by the profusion of vanilla-scented flowers at the Visitors Center. We didn’t recognize the species so I went exploring yesterday and found it both cultivated and wild.
Here are some other cool facts about Kentucky yellowwood:
Peregrine season is in full swing in Pittsburgh. We have peregrine families at Pitt’s Cathedral of Learning, at Third Avenue in Downtown Pittsburgh, and on 7 or more bridges. Are the bridge nests successful? Help us find out. Watch these bridges.
Art McMorris, PGC’s peregrine coordinator, has news from some bridges but needs updates from four sites. Watch to see if peregrines bring food to the sites listed below. If they do, there are chicks in the nest. If they don’t, keep watching. Report your findings (yes or no) in a comment here. If you visit regularly I’ll send you Art’s contact information.
Neville Island I-79 Bridge (also called the Glenfield Bridge), Ohio River
One or two peregrines have been at the Ambridge Bridge since last winter but only one has been seen in the past month. Are they incubating eggs? Stop by the Ambridge side of the river to view the bridge.
Monaca-Beaver Railroad Bridge -or- Monaca-East Rochester Bridge, Ohio River
A pair of peregrines usually nests in the Beaver, PA area but few people look for them. Check for peregrines on these two bridges: the Monaca-Beaver Railroad Bridge and the Monaca-East Rochester Bridge.
Route 422 Graff Bridge at Kittanning, Allegheny River
Peregrines have nested under the Route 422 Graff Bridge near Kittanning for many years but news is hard to come by. Stop by the best viewing area — under the bridge on the Armstrong Bike Trail — to check on their status.
Good News from Other Bridges
McKees Rocks Bridge, Ohio River
After the Pitt peregrine banding on 14 May 2019, PGC’s Dan Brauning and Sam Ruano stopped by the McKees Rocks Bridge to check for a nest and found 4 chicks too young to band. Dan estimates they were 12 days old so we expect them to fledge during the second week of June.
Tarentum Bridge, Allegheny River
This is the second year that an unbanded female peregrine with a dotted breast and a male peregrine banded black/green 48/BR have used the nestbox on the Tarentum Bridge. Susan Krouse saw the first food delivery on May 7 or 8. Tony Bruno reports noisy whining yesterday, May 19, by the mother bird (photo below). The chicks will probably fledge in mid-June. Watch them from the Tarentum boat ramp.
Westinghouse Bridge, Turtle Creek
John English reports that though he saw no peregrines at the Westinghouse Bridge yesterday, he certainly heard them! Begging calls from young and an adult whining. Stop by the bridge and you may be the first to see them.
No News from …
The remaining two bridges are unlikely to have nesting peregrines: Elizabeth Bridge over the Monongahela River (PennDOT covered the access holes) and the Hulton Bridge over the Allegheny River. Have you seen any recent peregrine activity at these sites? Let me know.
This morning 14 of us met at the Visitors’ Center for a bird walk in Schenley Park. We started with a view of the peregrine falcons at the Cathedral of Learning and ended with Best Bird in a tree near the Visitors’ Center — a Canada warbler!
Highlights in between included the sound of Tennessee warblers, scarlet tanagers, a yellow warbler, and an Acadian flycatcher, plus the sight of two ruby-throated hummingbirds, a wood thrush building her nest, a blue jay feeding nestlings, and a bay-breasted warbler in the tree canopy.
There were a heck of a lot of bullfrog tadpoles in Panther Hollow Lake. Why so many? They were almost gross.
After the walk we were milling about when Peter Bell took the photo at top and asked what it was. A Canada warbler! Several of us stayed 20-30 minutes to re-find it with some really great looks.
Andean condors usually nest on inaccessible cliffs 16,000 feet above sea level so it’s a real treat to see a pair nesting on camera at the National Aviary. The condor pair, Lianni and Lurch, expect their egg to hatch June 6-9.
Native to the Andes and nearby Pacific coast, Andean condors (Vultur gryphus) are the world’s largest flying bird. Their 10+ foot wingspan allows them to ride thermals in search of the carcasses of large animals that they scavenge. The condors are so majestic that they’re the national bird of Bolivia, Colombia, Chile and Ecuador and a national symbol throughout the Andean states.
Because the adults have no natural predators Andean condors have evolved to live long a long time (more than 70 years!) and reproduce slowly (only one egg every 1.5 to 2 years).
Unfortunately, due to habitat loss and secondary poisoning from hunted animals, the species is threatened in the wild and critically endangered in Ecuador. Zoos worldwide are participating in an Andean condor breeding program. Lianni and Lurch’s chick will increase the wild condor population.
If you watch the Cathedral of Learning falconcam every day, you’ve noticed a change in the peregrine family’s behavior. For at least a week now the chicks are often alone on camera. Where are their parents?
When peregrine chicks become mobile and start to grow feathers (2-3 weeks old) their parents give them space to walk around and test their wings. The older the chicks become, the more space their parents give them. You’ve probably noticed that Hope now perches at the front of the nest, not on the nest surface. This give the chicks maximum room to walk around.
The parents also perch nearby on the Cathedral of Learning within eyesight of their chicks. You can see Hope and Terzo with binoculars from Schenley Plaza but you can’t see them on your computer. The falconcam is below the parents’ perches because it’s the only place to put it in such a small area(*).
Yesterday, 17 May, the chicks were alone on camera for more than 82% of the daylight hours. But they weren’t alone.
If you watch the chicks’ behavior you can tell their parents are nearby. In the photos at top and below, the chicks are looking up and one is whining. He is whining at his parent.
We didn’t know which parent was being nagged until Terzo came down to feed them.
(*) p.s. If you watch the Hays eaglecam you can see the entire nest, nearby trees, and a long view across the river in winter. The eaglecam is attached to a taller/higher tree than the eagles’ nest. At peregrine nests, especially at the Cathedral of Learning, there is nothing across the way that is taller than the nest itself. That’s how peregrines like it.
