By mid-July all the peregrine nests in southwestern Pennsylvania will have either fledged or failed. Of the 11 sites we track in the region we know that 7 were successful, 2 had no evidence of nesting, and 2 had no observers during the critical nesting period (therefore no news). Here’s a summary updated on 22 July 2021.

Cathedral of Learning, University of Pittsburgh:
Most recent news: 5 July 2021.
Four young peregrines fledged from the Cathedral of Learning during 4 to 11 June. Their parents remain at Pitt after the “kids” have left, but the young have not gone far yet. Individually they circle back to see if their parents will feed them. The answer in July is no.
On 1 July I saw an adult perched on St. Paul Cathedral’s steeple watching a juvie on Webster Hall antenna (photos above).
On 2 & 3 July a youngster with pale head markings visited the nest, perhaps hoping for a handout. Ecco had been standing in the shadows but left quickly. (Slideshow below.)
On 5 July a juvie flew by outside my window. Peregrines are my Yard Bird.
Most recent news: 15 June 2021.
When young peregrines fledge from the Third Avenue nest they often have to be rescued from the ground and placed on the Rescue Porch to start over. We presume all three youngsters fledged this year, probably by 17 June, but we know of only one rescue. Maria Ochoa photographed him as he lingered on the rescue porch 12 to 15 June. No news is good news at this site.
Monongahela Watershed: Westinghouse Bridge:
Most recent news: 4 July 2021.
Dana Nesiti has visited the Westinghouse Bridge often in the past month and brought back some great photographs with news of the two juveniles.
On 9 June a young peregrine walking on the Westinghouse Bridge (on the road!) was rescued by Game Warden Doug Bergman and checked for injuries at HAR Verona. The bird was healthy so Berman returned it to the bridge catwalk that same day.
Though both juveniles are present, it was two weeks before Dana saw them at the same time. On 26 June he found the entire family of four (slideshow above). Last weekend the parents were still supplying the youngsters’ food. The slideshow includes a photo from the Fourth of July.
Ohio River: McKees Rocks Bridge, Allegheny County:
Most recent news: end of June 2021.
About a week ago Joe Fedor contacted Art McMorris with news that he had seen fledglings at the McKees Rocks Bridge. Though we don’t have photos, we do know the nest has been successful.
Ohio River, Ambridge-Aliquippa Bridge:
From Art McMorris on 13 July 2021: “At least one peregrine, and often a pair, has been seen at the Ambridge-Aliquippa bridge quite regularly throughout the nesting season. Most recently a single peregrine June 30 per an eBird report by Mark Vass. But no evidence of nesting or young.”
Ohio River, Monaca – East Rochester Bridge:
Most recent news: 19 June 2021.
This year observers thought the peregrines would nest at the Monaca Railroad Bridge but the birds used their alternate site instead, the Monaca-East Rochester Bridge.
After Mark Vass reported them in mid June, Jeff Cieslak stopped by with his camera.
Though I had seen the falcons courting on the Monaca RR bridge earlier in the year, it seems they nested on the Rt 51 bridge [Monaca-East Rochester Bridge]. This morning, there were two adults and two juveniles out and about. The adults seem to like the electrical tower just west of the bridge on the Monaca side, which you can see from the adjacent neighborhood. I would advise against walking across the bridge (even though there is a sidewalk), as the falcons seem to find pedestrians upsetting.(Hat tip to Mark Vass for spotting them in the area earlier in the week)— Jeff Cieslak, Pittsburgh Falconuts on Facebook GROUP, 19 June 2021
By now the young are flying well, so it’s safe to walk across the bridge.
Allegheny River, 62nd Street Bridge:
Nesting had not been reported at the 62nd Street Bridge since 2019 though peregrines were seen occasionally this spring from 62nd Street to the Aspinwall railroad bridge.
On 19 July Marie left a comment that she and some friends had seen and heard two peregrines while kayaking under the 62nd Street Bridge on 18 July.
I visited the bridge on 21 July and found an unbanded adult peregrine perched and preening on the superstructure. The bird “kakked” at something on the Sharpsburg side of the bridge, clearly territorial.
When the peregrine flew off I packed up to leave, then saw and heard a juvenile peregrine chasing and begging from the adult. Success! Peregrines nested at the 62nd Street Bridge this year.
Allegheny River, Tarentum Bridge:
Most recent news: 10 June 2021.
Three youngsters at the Tarentum Bridge fledged six weeks ago, then one went missing after 26 May. By the week of 7 June the remaining two were flying well enough to leave the bridge when construction began. The last update came from Dave Brooke on 10 June when he found the adult female perched at the bridge.
