Peregrine Update, Pittsburgh

Published by under Peregrines

Gulf Tower peregrine family:  Yesterday morning, June 19, I heard from Amanda McGuire that the Downtown peregrines are hanging out near Point Park University and Oxford Center.  You may remember her balcony at Lawrence Hall was the rescued juveniles’ way station last year, the place where they rested near the (former) nest after rescue from the ground.  At 7:45am Amanda texted me saying:

Just ran for my life… There’s a peregrine on a little perch a floor below my balcony… and another one circled over me as I was looking over the edge.  |  They’ve been loud the past couple of days. Yesterday around 7pm there were two flying around Oxford Center.  |  I thought about going back out to get you a picture… but after that second one swooped by, I think I’m just gonna stay inside.  | One of them has the voice of their dad. Volume-wise at least… Luckily it’s not as long winded.

If you want to see the Gulf Tower peregrines, check out the area only three to four blocks from the Gulf Tower.

Westinghouse Bridge peregrine banding, Tuesday July 1, 10:00am:  The Westinghouse Bridge family is maturing later than other Pittsburgh area nests (perhaps this is a re-nesting).  On July 1 the PA Game Commission will band the nestling(s) when they are approximately 20 days old.  PGC’s Peregrine Falcon Coordinator, Art McMorris, writes:

We will meet at 10:00 AM on US Route 30 east of the bridge. From the east, driving westbound towards the bridge, there is a pull-off on the right side of the road about 1/3 mile before the bridge, across from Clyde Ave. … PennDOT will set up the snooper crane and we will access the nest via the crane. Everyone going onto the bridge deck to observe should have the standard safety equipment: at a minimum, a hard hat and safety vest. Others who would like to observe can watch from locations near the bridge. Observers can help by taking photographs in hopes of documenting the identity of the adults.

Fledge Watch Opportunities This Weekend

Wtaching the eagles at Hays (photo by Kate St. John)

Want to see peregrine falcons or bald eagles?  This weekend four sites in the Pittsburgh area have young raptors ready make their first flight.

Watch Peregrines at …

  • Monaca-East Rochester Bridge:  Four juvenile peregrines are fledging at this site June 11-16.  The nest is over water so your watchful presence may save a young peregrine’s life if it lands in the river (you can alert a nearby boater).  There are no officially organized times to watch at this bridge though I can tell you I plan to stop by on Saturday.  Click here for a map.
  • Neville Island I-79 Bridge:  One female peregrine is due to fledge from this site June 14-19.  Anne Marie Bosnyak and Laura Marshall will be at the adjacent Port Authority Park-n-Ride and Fairfield Inn parking lots for much of the weekend. I plan to visit too at 9:00am Saturday.  Watch this blog or Pittsburgh Falconuts for dates and times.  Click here for a map.

Watch bald eagles at…

  • Hays eagle nest:  Three eaglets have been flapping like crazy on camera this week so it’s only a matter of time before one of them makes his first flight.  Dedicated eagle fans will be watching from the Three Rivers Heritage Bike Trail all weekend.  Bob Mulvihill from the National Aviary will be there on SUNDAY at 9:00am.  C’mon down any time.  It’s free!  Click on Bob’s name or here for a map.
  • Harmar eagle nest:  This nest is much harder to watch since the Hulton Bridge construction closed the small parking lot with the best view.  Eagle fans have been known to stand by the side of busy Hulton Road in Oakmont. (Yow!)  Before leaf-out there was a good, safe view from the patio behind Oakmont High School. Bring a birding scope and look for watchers on the Oakmont side of the river. If you find a good place to stand, leave a comment with directions.

The weather will be great for Fledge Watching.  Let’s get outdoors!


p.s. Happy news from Westinghouse Bridge:  On June 11 PGC’s Tom Keller found a day-old hatchling at the Westinghouse Bridge peregrine nest (two eggs still unhatched).  PGC will band the chick(s) in 18 to 22 days.  Peregrine monitor John English is looking forward to a Fledge Watch in mid July.

Falcons Stick Together

American kestrel fledgling at Engineering Hall, Univ of Pittsburgh (photo by Michelle Kienholz)

This story has a sad ending but the middle is so amazing that it’s worth the telling.

At 10:00am Michelle Kienholz texted me with an odd sighting at Pitt’s Graduate School of Public Health: “Peregrine on GSPH? One of the Cathedral of Learning peregrines is yelling and dive-bombing it.”

Michelle sent a cellphone photo of the attacked bird perched on the windowsill but neither of us could determine the species.  Michelle didn’t have binoculars and her photo was tiny.

Forty-five minutes later she texted again after she saw it more clearly:  “Red-tailed hawk — taking quite a beating from E2 still.  Can’t tell if windows are affecting how wings held or if injured but I see red-tails on the building all the time.  45 minutes on the same cramped ledge with a crazed falcon seems odd.  … Doesn’t look especially stressed though.”

Almost an hour later at 11:30am:  “Red-tail moved to Sennott Building, so he can fly.”

But this was not the end of it.

At 1:30pm Michelle sent an email about another bird of prey perched at the entrance to the Engineering Building.  Observers had seen him hit a window in the early morning.  Melissa Penkrot at the School of Engineering was concerned because this juvenile male kestrel had been perched there since 7:00am.

In between meetings, Michelle ran down to check on the kestrel while Melissa called the Game Commission. The kestrel continued to stand in plain sight so Melissa put up a sign so folks would not try to touch it.  Interestingly, she could see the Sennott Building from the kestrel’s location.

Michelle returned an hour later and saw the kestrel hop up on the rust-colored sculpture and make a slow wobbly flight across the street.  Before she returned to work she told the security guard at the parking garage that the Game Commission was coming for the bird.  He assured her he’d be there into the evening and would keep an eye on it.  That was at 2:45pm.

Alas, when Michelle returned at 7:00pm the security guard told her the red-tail had barely waited for her to leave.  While the kestrel’s back was turned the red-tail swooped in and killed him.  Not a happy ending.

But there is a happy middle.

In the morning E2 spent at least 45 minutes attacking and finally moving that red-tailed hawk away from the area.  E2 was as focused and relentless as he is when his own fledglings are threatened.  Yet he has no babies this year.  Why did he attack the red-tail?

I think E2 recognized the fledgling as a baby falcon — not a peregrine, but certainly a falcon — and his protective instincts kicked in.  He doesn’t have his own “kids” this year but when he saw a dazed juvenile falcon he knew the red-tail was up to no good and did everything in his power to move the danger away.  He did a good job.  The red-tail was deterred.

Vulnerable American kestrels often fall prey to red-tailed hawks.  The kestrel’s own parents could not have protected him, but a peregrine did.

Falcons stick together.


p.s.  Kestrels are known to help peregrines: see this blog from 2012.

Peregrine News Around Town

Published by under Peregrines

Peregrine activity at Pittsburgh’s two fledged nest sites has moved out of easy view but three locations still await the excitement of first flight.  Here’s the latest peregrine news in a long blog post.  Don’t miss the end as the best is always last.


Cathedral of Learning:

Yesterday Tom Keller of the PA Game Commission removed Dorothy and E2’s unincubated egg.  This was not to change Dorothy’s mind about standing at the nest but to test the egg.  Dorothy and E2 always visit the nest at this time of year and Dorothy loves to sunbathe there.

Some of you were worried that the peregrines were sad about the egg.  I don’t think so.  Not sad, just bored.

Meanwhile the infrared lamp that provides night vision has burned out so the nighttime video looks like “snow.”  We will replace the lamp before the next nesting season.


Gulf Tower:

Last Saturday at Fledge Watch we saw two juveniles on the Gulf Tower roof while the remaining three nestlings waited to launch.  By dawn on Wednesday only one female remained at the nest.  She looked as if she was ready to fly but she was cautious — a good trait in the urban environment where buildings, glass, and chimneys pose unnatural threats to survival.  She flew on Wednesday.

That same day at the U.S. Steel Tower, a friend of Steve Gosser’s sent him a mystery photograph, “What is this bird?”  A juvenile peregrine outside the office window!  The Gulf Tower “kids” are exploring Downtown.

No peregrines have been confirmed at the Green Tree water tower for many weeks though several of us have looked while driving by. This site has been disappointing for two years in a row. If you do see a peregrine at the water tower, let me know.


Tarentum Bridge:

Though there were two fledglings at the Tarentum Bridge on May 29, only one has been seen since then.  Time will tell if the second one is merely hiding or gone missing. If you see one or both at Tarentum, let me know.


Westinghouse Bridge:

McKees Rocks Bridge:

Old news, but good news…  On May 23, the PA Game Commission and PennDOT used the bucket truck to search for the peregrines’ nest at the McKees Rocks Bridge. Despite their efforts they were unable to locate the nest because the peregrines defended an inaccessible area. They confirmed that the female is unbanded while the male is still Bravo (V over H (blk/green)) from Cleveland’s Terminal Tower in 1999, son of Zenith and Bullet. He was first recorded at McKees Rocks in 2008. This year he’s 15 years old. His unbanded mate indicates that female peregrines from remote sites (or perhaps from man-made inaccessible sites) are finding homes in Pittsburgh.


Neville Island I-79 Bridge:

At the Neville Island I-79 Bridge one female chick is getting ready to fledge.  She was 22 days old when banded on May 28 so she’ll probably fly June 14-19.  The nest location makes for an easy Fledge Watch so stay tuned for dates, times and directions. The Watch will probably begin on Friday, June 13th — perhaps sooner! Pittsburgh Falconuts, look for news from Anne Marie Bosnyak.


Monaca East Rochester Bridge:

Four chicks — three females and one male — were banded at the Monaca-East Rochester Bridge on May 21 at 18 days old.  They will probably fledge from June 11 to 16.  Start watching on June 10 (or earlier!) and you’ll see lots of activity beneath the bridge.  It’s easy to see the bridge from the community park on the Monaca downriver side.  Keep an eye out for the mother peregrine!  I hear she is very fierce.

News From Gulf Peregrine Fledge Watch

Published by under Peregrines

Gulf Tower Fledge Watch, 31 Mat 2014 (photo by Kate St. John)

An enthusiastic crowd of seven watched seven peregrines yesterday afternoon at Flag Plaza.  To beat the heat we stayed in the shade.

The view from the plaza takes in all the key buildings where Downtown Pittsburgh’s peregrines hang out plus a lot of airspace nearby.

The Fledge Watch view from Flag Plaza (photo by Kate St. John)


We saw all five juveniles — three at the nest zone and two on the Gulf Tower pyramid roof.  From their behavior we surmised that:

  • Two have fledged.  Last night we saw a juvenile fly around the roof of the U.S. Steel Tower and another on the stone “ball” on top of Gulf’s pyramid.  Two juveniles spent this afternoon on the pyramid steps — probably the same two.
  • Three juveniles spent all day at the nest zone but often out of webcam view.  They use adjacent ledges (same floor) to make short practice flights from pillar to pillar.  If you’re watching on the Internet you think they’re gone.  Nope!
  • All five juveniles did some energetic flapping.  We saw one fly when Dori stopped by the pyramid with a treat.
  • Louie and Dori perch on the high corners of the U.S. Steel Tower (UPMC) to watch their “kids.”  At one point both peregrine parents were on U.S.Steel and the five juvies were in view on Gulf.  The entire peregrine family!

When peregrine watching was dull, local wildlife caught our attention including: a male American kestrel, a northern mockingbird, chimney swifts, northern rough-winged swallows, American robins, common grackles, a yellow warbler, house finches, song sparrows, house sparrows, and European starlings.  And we saw a groundhog climb a tree by the parking lot!  Going up was easy for this large rodent.  Down was a stumble.

Neville Island Peregrine News

Published by under Peregrines

Male peregrine at Neville Island I-79 shouts as Dan Brauning takes his picture (photo by Anne Marie Bosnyak)

Frozen in time, the female peregrine at the Neville Island I-79 Bridge shouts at the PA Game Commission’s Tom Keller and Patti Barber as they arrive to band his nestling on Wednesday May 28.  Patti took his picture.  This male is banded!  We won’t know his identity until Patti’s photo tells the tale.

I was out of town Wednesday morning and missed the excitement.  Anne Marie Bosnyak, Peter Bell, and Laura Marshall observed the banding from nearby.  While we wait for official news from the Game Commission, here’s what we know so far.

Based on Anne Marie’s close observations, we think incubation began on April 1.  Hatching probably occurred on May 6 when Anne Marie watched the male bring food into the nest and then bring it back out when the female — still in the nest — told him “Not yet.”  On May 25 Anne Marie used her new camera (yay!) to confirm that the female is still Magnum, hatched in 2010 at Canton, Ohio.

Below, Magnum walks the girder to the nest hole on May 25.  The floor of the nest is that plate with many rivets.

Thanks to PennDOT’s assistance, Patti and Tom got access to the site on Wednesday at 9:00am.  To everyone’s surprise, Magnum stayed in the nest while the male flew around and shouted.  (Typically the female attacks while the male stays back.)  PGC found only one chick in the nest, a female, plus some unhatched eggs which they took for testing.

Here Tom Keller holds the chick for banding.

Congratulations to Magnum and her mate whose chick will fledge June 14-19.

Meanwhile we look forward to hearing of her father’s identity.

Gulf Tower Fledgling Visits Liberty Center

Published by under Peregrines

@PondLadyDi had a visitor outside her office this afternoon! Here are two tweets I received with pictures of one of the Gulf Tower fledglings.

Liberty Center, at 1001 Liberty Avenue, is almost due north of the Gulf Tower with a clear view of the nest.

Two At Tarentum

Published by under Peregrines

A small, enthusiastic crowd was on hand yesterday morning for the peregrine banding at the Tarentum Bridge, rewarded by close looks — and photos — of the two peregrine chicks: one male and one female.

The event began at the boat launch parking lot where viewers watched as the PA Game Commission’s Dan Brauning and Tom Keller and the PennDOT crew swung the bucket under the bridge to the nest hole on the main-channel arch.  We knew the nest location because Rob Protz, myself, and others had seen juvenile peregrines peeking from the hole.

The adult peregrines attacked but could not deter the banders.  However, when the bucket got to the nest hole the two chicks were huddled far inside out of reach.  Tom Keller crawled into the hole!  Look at him stand on the bucket edge before he disappeared inside!  Yow!

Tom retrieved the chicks and the bucket swung up to the sidewalk to weigh and band them.  The crowd joined to watch.

Each chick received two bands: US Fish & Wildlife on the right leg, color band on the left leg.  Here, Dan Brauning crimps the silver USFW band.

Dan estimated the chicks were 35 days old yesterday — only four to nine days away from first flight.  Rather then put them back in the nest hole, exposed over open water, Dan wet them down (to keep them from trying to fly right away) and placed them on the mid-river bridge pier where there’s a good “runway” for take off.

Stop by the Tarentum Bridge soon to watch these young peregrines.  They’ll be making their first flight some time between Memorial Day and the end of the month.

Gulf Tower Fledge Watch: May 31, June 1

Published by under Peregrines

Location of Flag Plaza (via John Enlgish on Pittsburgh Faclonuts Facebook page) I don’t know about you but without a successful nest at Pitt this spring I’m starved for a Fledge Watch at Schenley Plaza.  It’s always been a great time to get together and indulge our passion for peregrines.

With that in mind, Pittsburgh Falconut John English and I are going to hold a Gulf Tower Fledge Watch at Flag Plaza on Saturday May 31 and Sunday June 1.

My “guess-timate” is that the Gulf Tower chicks will fledge between May 29 and June 3 with the most exciting activity on Sunday June 1.

Where: Flag Plaza (Boy Scouts building), 1275 Bedford Avenue, Pittsburgh, PA 15219
When:  Saturday May 31 & Sunday June 1, noon to 4:00pm, weather permitting.

John or I (or both of us) will be on site during those times — though not if it’s raining or stormy.

Come for as little or as long as you’d like.  Bring binoculars if you have them.

Hope to see you there!

Please leave a comment below if you plan to come.
