Some time yesterday morning while no one was watching — not even his parents — the Pitt peregrine chick made his first flight and had a big adventure.

He landed near Heinz Chapel and climbed the steps, was guarded by Pitt Police and returned to his nest at 2:40pm by a PA Game Commission Officer.

Two blocks away at Schenley Plaza, 10 to 12 of us had been at Fledge Watch since noon with a clear view of the airspace between the nest and Heinz Chapel.  We never saw him fly and his parents, Dorothy and E2, were acting normally, flying together, spending time near the nest and looking into the gully as if the chick was there. As Fledge Watchers we cue on the parents to find the “kids.”  Dorothy and E2 didn’t even glance toward Heinz Chapel.  None of us knew.  He flew under the radar.

Yesterday was Music Day at the Schenley tent so we couldn’t hear our cellphones ring but at 2:30pm we suddenly saw calls and text messages that Jody Rosenberg reported the chick on the ground with Pitt Police at Heinz Chapel.  Talk about confusion!  We’d been watching for 2.5 hours and saw nothing!  How could this be true?

And in fact, at that moment the bird was in the elevator on his way back to the nest.   I ran to the Cathedral of Learning and met the Pitt Police and PGC Officers when they came down to the lobby.  Apparently the bird was reported before noon and yes, PGC confirmed that he was banded “43/BR.”   We could see him on the webcam on our cellphones.

Back at nest, he yelled at his rescuer and his parents, had a big dinner and a good long afternoon nap.

Today he’s ready to try again.

Ever since the Pitt peregrine nestling jumped to the green perch, online watchers are a-buzz with this question:

When will the Cathedral of Learning nestling fly?

Answer: We don’t know.

It’s always difficult to predict Fledge Dates. Though the rule of thumb says they fledge 38-45 days after hatch, the timing depends on age, sex and physical condition.  Some break the rules, as did the early males this month at Neville Island Bridge and Downtown.

This year’s Pitt nestling is even more challenging to predict because:

• The chick has (or had) delayed development.  At 19-days-old it had 14-day-old feather growth.  Will it fledge 5 days late?  We don’t know.
• Fledge dates are earlier for male nestlings than for females because the males are lighter weight.  Is this bird a male or a female?  We don’t know.

Thoughts on the bird’s sex keep fluctuating.  The size of his legs/feet say he’s male (males have smaller feet), but when we see she’s nearly the size of Dorothy now we think she’s female.

And none of this matters anyway.  The bird will fly on its own schedule.

At the Cathedral of Learning here’s what peregrine chicks do as they approach Fledge Date:

1. First adventure: Nestling “Ledge Walks” off camera and/or explores below the nest.  You can’t see him but he has not flown yet.  (Online video watchers, for you the bird will simply disappear.  Click the links to see pictures and videos showing what actually happens.)
2. For several days: More adventures back & forth to the nest.  He has not flown yet.
3. At some point: Leaves the nest for a nearby ledge and doesn’t return.  On the day this happens he has not flown yet.
4. A couple of days after Step 3 the nestling flies for the first time and lands up high on the Cathedral of Learning.

WARNING:  During this period curious people can scare the chick into premature flight that will end his life in a crash.  No close view or photo is “innocent.”  If you’re in Pittsburgh, stay away from the nesting area.  You don’t want to be the one who scared the chick and killed him!

Online watchers, you will know the bird will fly in a few days when you don’t see him on camera anymore.  Your watching will end long before the bird flies.

In Pittsburgh our watching will be extended as we view the peregrines from Schenley Plaza and later watch the juvenile on campus into the month of July.

Pittsburgh Peregrine Fans, come on down to the Schenley Plaza tent and I’ll show you where to look.  Watch Dorothy and E2 do flight demonstrations and prey exchanges!  See Dorothy beat up turkey vultures, even bald eagles!   Click here for the calendar. p.s. I won’t be there in rain or thunder.

Late yesterday I received this summary of the Pitt nestling’s blood test results from the Pennsylvania Game Commission. Some of you have expressed an interest in this information so I am posting it here.

“When examined on banding day, the nestling was found to be significantly infested with blood-sucking ectoparasites and was given appropriate treatment.

Blood tests conducted by Dr. Wagner revealed that the nestling was anemic, probably due to the ectoparasites, but the complete blood count (CBC) and blood chemistry results were within normal limits. The only abnormality was a low packed cell volume indicating anemia.

Tests for West Nile Virus, Avian Influenza Virus and internal parasites were negative.”

The blood sample was taken on Banding Day, 29 May 2015, at the Cathedral of Learning when the peregrine chick was 19 days old.

Today the Downtown Pittsburgh nest is empty.  All three young peregrines are out in the wide world.

On Wednesday Lori Maggio captured a portrait of #3 waiting at the nest ledge for just the right moment to leave.

By midday Thursday the bird had already flown and been rescued when Lori saw her on the Frick Building near the rescue porch.

#3 didn’t linger.  She soon flew to join her brothers on another high building.  Read about her adventures here.

As I mentioned last evening, if the young peregrines stay up high the official Downtown Fledge Watch is over today.  (Official Fledge Watch ends when the birds have graduated to the upper air and are out of ground-based danger.). UPDATE AT 9:00AM: Rain and there are no peregrines near the ground. We’re done!

You can always watch the peregrines on your own schedule.  If you do please post a comment to tell us what you see.  We’d love to know!

Today I’ll be at two peregrine sites:  Downtown Fledge Watch (8:15am to 10:00am) and Pitt Peregrine Viewing (12:00pm to 2:00pm).

Join me at the Schenley Plaza tent in the days ahead to watch the peregrines at the Cathedral of Learning.  Click here for the complete Pitt peregrine calendar.  NOTE: I will not be out there in rain or thunderstorms.

p.s. Don’t forget the Westinghouse Bridge peregrine banding on Monday, June 22 — full details here.

That was quick!  I thought we’d have to watch on Saturday, but if all goes well tomorrow Fledge Watch will end on Friday June 19.

Fledgling #3 flew so early today (June 18) that our early morning watcher, Doug Cunzolo, didn’t see it happen.  He found a silent nest and no parents.  Doug checked everywhere for #3 but found nothing.

I couldn’t find her either but her parents gave me a clue.  At 9:00am Dori plucked prey on the Macy’s roof, then flew with it up Grant Street toward the City-County Building.  On Grant Street Louie watched the front of the Courthouse from a high corner on Frick.  They must be looking for someone.  Was #3 on the Courthouse?  Marcia Cooper examined the Courthouse ledges from inside the Frick Building but found nothing.

#3 was not on the Courthouse.  She was in it.

Someone found her on Ross Street, put her in a box and took her to the County Sheriff inside the Courthouse.  The Sheriff called the Game Commission and PGC Officer Puhala delivered her to the rescue porch.  Frank Baker took her picture (above) just after she arrived.

Within 10 minutes #3 had jumped up to the parapet and was exercising her wings.  Within an hour she’d flown from Frick to another high building, perhaps to Citizen’s Bank where at least one of her brothers was hanging out.  Several of us saw Dori and Louie make food deliveries to that roof.

This photo by Terry Wiezorek shows a juvenile peregrine on Citizen’s Bank.  It might be #3 because she would still be exercising her wings on Day 1 of her flight career.

Up high is good!  With parents is good!

If the juvies continue to stay up high with their parents on Friday, then the official Fledge Watch ends at the end of the day June 19.

Thank you, everyone, for all your help!
