TBT: New Tenants?

On Throw Back Thursday (TBT), a 2014 replay of something that’s happened only three other times since 2008…

Word must have gotten out that the Pitt peregrine nestbox wasn’t used much this spring. Some surprising new tenants stopped by last month.

On June 21 a pair of pigeons inspected the site for three hours.

“Wow, honey!  Look at this perfect location.  I’ve heard it’s dangerous up here but this area looks completely safe.  What a cool place to nest.  We could move in immediately!”

After three hours they began to wonder… “Did you hear something? I have a creepy feeling we’re in danger.”

The pigeons never moved in.  ;)

Bridge Gone, But Not Its Peregrines

Published by under Peregrines

I-90 Inner Loop Bridge demolished in Cleveland, Ohio, 12 July 2014 (screenshot from video)

Perhaps you saw the news Dick Rhoton sent me of the I-90 Inner Belt Bridge demolition in Cleveland last Saturday, but you might not have realized its significance to birds.

The bridge is gone, but not its peregrines.

The old span, built in 1959, was home to a pair of peregrines for all their productive years but was also rusty, corroded and becoming dangerous.  Pictured below on a foggy day in a 2012 by Chad+Chris Saladin, you can see a pier of the new I-90 bridge being built to its right.   The new span is finished now, carrying traffic in both directions while it waits for the eastbound lanes to go up where the old bridge stood.

Though a nest box was provided on the new span, Newt and Bolt chose the old bridge as usual this year and raised one juvenile who fledged at the end of June — all this despite the fact that demolition contractors were taking apart the bridge around them.   By the time of the final implosion, their home was a gap-toothed structure with four of its five spans already gone.

Here’s a photo of the nest site in 2012 by Chad+Chris Saladin.  Look at the condition of that bridge!  Traffic was still using the bridge when this picture was taken.

Everyone worked together to make sure the peregrines were safe.  As demolition day approached, Ohio Division of Wildlife (DOW), Ohio Dept of Transportation(ODOT) and the demolition contractor discussed the peregrines’ status and decided that with two weeks of flight experience the juvenile would be able to get out of the way.  The remaining danger was that the birds might be perched on the old structure during the explosion so the contractor scheduled a warning blast to tell the birds to evacuate.

Saturday morning Laurie and Jenny from DOW were stationed with binoculars and spotting scope to watch for the peregrines.  The warning blast went off five seconds ahead of the main blast and then ….  BOOM!  Click here or on the screenshot at top to watch the bridge collapse.

After the dust cleared at least two, maybe all three peregrines, were found.  As Chris Saladin wrote:

“I’m thrilled to report that the juvie and at least one adult were spotted by DOW’s Laurie and Jenny following the explosion of the remaining parts of the dismantled old I-90 Bridge this morning!! We would assume that both adults are probably okay, since two of the three peregrines were spotted (and if the juvie “sensed” her need to leave the structure one would assume that each adult would have an even more developed sense of danger and would know to depart). … [Laurie] let us know that after the “dust cleared” she and Jenny were able to see the juvie through the spotting scope and then saw an adult fly by the juvie. Additionally, Tom from ODOT let Laurie know that as DOW was moving to a different angle for viewing he saw one adult plucking prey on a top beam of the fallen span, about 30 feet off the ground!”

We hope Newt and Bolt will find the nest box on the new bridge just as inviting as the old one.  It will be impossible to “go home” next spring.

Peregrines, Eagles and Two Events

Here’s the latest news of Pittsburgh’s peregrines and bald eagles plus information on two events:  Westinghouse Bridge Fledge Watch, July 18-20, and the Eagle Lovers Outing on August 2.

Peregrine News

Westinghouse Bridge
Peregrine season isn’t over!  Two nestlings at the Westinghouse Bridge will fledge next weekend.  John English has organized a Peregrine Fledge Watch for Friday July 18, 6-8pm, Saturday July 19, 2-4pm and Sunday July 20, 2-4pm.  Click here and scroll down for directions.  Please contact John at Pittsburgh Falconuts Facebook page or leave a comment on this blog if you plan to attend.  I’ll be there on Saturday. C’mon down!

Green Tree Water Tower
Green Tree wins the prize for strangest peregrine behavior.  After a long absence during the heart of the breeding season, a pair of peregrines is again at the Green Tree water tower.  What happened between April 1 (the date of Leslie Ferree’s photo above) and now?  Did the old pair leave and a new pair show up?  Stop by the Green Tree water tower and tell us what you see.  Peregrines always surprise us.
UPDATE, 16 July:  Tim and Karena Johnson visited the water tower recently and saw a pair of red-tailed hawks perched on the railings. Since we know that peregrines drive out red-tails — and all other hawks — within their territory it’s probable that the peregrines are not at the water tower at all.
UPDATE, 17 July: Mary Jo Peden, one of the long-time Green Tree monitors, saw a peregrine at the water tower today. It had been exactly two months since she last saw one there. So, yes, they are there but not often.

University of Pittsburgh, Cathedral of Learning
Dorothy and E2 are present every day but not often seen because they’ve found new hiding places in which to molt.  The snapshot camera shows they still visit the nestbox for brief bowing sessions (last Friday, above).  Meanwhile the streaming falconcam and infrared array have both shut down and need an on-site visit from a skilled technician with access to the ledge.  This maintenance will be scheduled in the fall.

Rob Protz reports that “mom” peregrine (nicknamed Hope) was at the Tarentum Bridge with her remaining juvenile for several hours on July 8.  The youngster, whom Rob calls “Screecher,” was begging loudly for food.  It sounds like Hope is weaning him from dependence on his parents.  Pun intended!

Gulf Tower, Monaca Bridge, Neville I-79 Bridge and McKees Rocks Bridge:  No updates from any of these sites but at this time of year that’s good news.


Bald Eagle News

All three eaglets fledged successfully in late June and are flying so well that they’re hard to find. They are out and about learning the ways of eagles and how to find food.  Meanwhile, to wrap up the season, Eagles of Hays PA and Urban Eagles in Pittsburgh are planning an Eagle Lovers Outing and tour on Saturday August 2, starting at 11am at Vallozzi’s Restaurant in Greensburg, PA.  Click here for more information.

Harmar and Crescent Township  There’s no update from our other eagle sites but, as for peregrines, no news is good news at this time of year.


With no nest activity, the next six months will be very boring for peregrine and bald eagle fans.  We’re looking forward to 2015.

Two Peregrine Chicks at Westinghouse

Published by under Peregrines

Just when you thought peregrine nesting season was over, there’s one more nest remaining to fledge in Pittsburgh.

Yesterday morning Tom Keller of the PA Game Commission rode with PennDOT in their graciously provided bucket truck to band the nestlings at the Westinghouse Bridge.  This late nest was first confirmed on May 20 when Dan Brauning and Tom Keller found the female incubating three eggs.  On June 10 Tom confirmed the first hatchling.  Yesterday he banded two females.  (One egg didn’t hatch.)

This late-in-the-season nest cycle is probably a re-nesting after the first attempt failed.  Nest failures at natural cliff sites can be caused by predation but this location is so inaccessible that the re-nest is probably due to a changeover in adults after a peregrine-vs-peregrine challenge.  The banded female, Hecla, hatched in 2009 at the Ironton-Russleton Bridge in Ironton, Ohio and has been present at Westinghouse since 2012.  Perhaps her banded mate is new but no one has been able to read his bands.  He’s still unidentified.

Westinghouse site monitor (and proud “papa”), John English, organized a Banding Watch under the bridge.  Thanks to photos from watchers Maury Burgwin and Donna Memon, I’ll tell the rest of the story in pictures.

Downtown Lunch

Published by under Peregrines

Is this a flock of crows?  No!

Anne Marie Bosnyak went Downtown last Saturday to find Pittsburgh’s Gulf Tower peregrines and she hit the jackpot.  At the corner of Fifth and Wood she saw two on the edge of the Citizen’s Bank Building.  As she watched, an adult arrived with food and four juveniles popped in for a meal.  From the looks of this, I doubt they were planning to share.

When they aren’t hanging out elsewhere the youngsters have lunch at the U.S. Steel Tower where Patti Mitsch can watch them outside her 38th floor window.  Here are four snapshots from cellphone videos she shared with me on Facebook.

Take That, You Pesky Airplane!

Published by under Peregrines

Adult female peregrine attacks remote-controlled model glider (photo by Steve Shinn)

It looks like Photoshop, but it’s not.  The bird and the plane are actual size, frozen in time in Steve Shinn’s photograph.

The peregrine is a wild bird who nests on the seaside cliffs near Los Angeles, California.  She has “kids” on the cliff and won’t tolerate anything flying near them.  It doesn’t matter what it is.

The plane is a radio-controlled glider, guided by a human on the ground.  Model airplane enthusiasts love the wind above the cliffs for testing their equipment.  They have not thought that peregrine falcons could be a hazard.

Steve Shinn stops by the cliffs frequently during peregrine nesting season to capture awesome photos of their activities.  He was lucky to be there the day this female peregrine had had enough.

Annoyed by the glider invading her airspace, she flew out ahead of it, talons dangling, watching her chance.

Boom!  She grabbed it in mid-air and bit the “neck” to sever its spinal cord but it didn’t die quickly.

Steve writes, “Having grabbed this invader, she naturally wanted to chew off its head.  Fiberglass is a tough nut to crack even for a Peregrine.  … She has been reported to have ripped off the canopy of one plane and caused another to plunge into the ocean.”

You’d think the glider fans would learn.

“Take that, you pesky airplane!”

Peregrine Update, Pittsburgh

Published by under Peregrines

Peregrine falcon (photo by Chad+Chris Saladin)Here’s a quick update:

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.

Juvenile American kestrel at Engineering Building (photo by Michelle Kienholz)

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.
