UPDATE as of Saturday 25 March 2023, 7:15 PM: MORELA IS AT THE NEST!

News as of Saturday 25 March 2023, 8:00am:

On Wednesday morning, 22 March, I began to wonder if a female peregrine was challenging Morela at the Pitt peregrine nest. Morela hasn’t been seen on the falconcam since Tues 21 March at 3:32pm and two days have passed since I last saw her perched on campus (Wed 22 March at 4:14pm). Meanwhile Ecco waits and watches at the Cathedral of Learning.

Though none of us have seen any female peregrine for two days Ecco sometimes sees one in the sky — or maybe more than one. Yesterday afternoon he called to her from the nest. Whoever she was, she didn’t come in. Only Ecco knows whether she was Morela or the challenger.

Eventually a female will join Ecco at the nest so watch carefully at that point. Is she Morela? Or someone new?

Will there be eggs and chicks this year? No one can tell. Like Ecco, all we can do is watch and wait.

The drama continues off camera for now.

Stay tuned at the National Aviary Falconcam at the Cathedral of Learning.

Is There A Challenger At The Pitt Peregrine Nest?

22 March 2023

See Status Updates at the end.

As I mentioned yesterday morning Morela was looking as if she’d lay an egg any minute, but yesterday everything changed. After days of lounging at the nest and crouching over the scrape Morela was barely on camera at all. When she returned in the afternoon she looked vigilant. Meanwhile Ecco spent 2.5 hours waiting at the nest, sometimes watching the sky.

What’s up with Morela? Why isn’t she trying to lay an egg? I think she may have a challenger who’s keeping her busy.

From just after midnight on 21 March through 7:00am 22 March (today) this timelapse video shows how both peregrines are absent from the nest. I’ve provided a description of the action below the video, some illustrated with snapshots.

Activities on the video:

  1. Morela is at the nest nearly continuously on Tuesday 21 March from midnight to 4:50am when she jumped to the roof, still present at the nest though not visible.
  2. Morela looks relaxed for an hour at the nest 9:50-10:57am. Then she disappears.
  3. Ecco takes her place for more than an hour 10:59am-12:02pm. Ecco has a bright orange beak and legs compared to Morela’s pale yellow.
  4. Ecco stops in briefly and watches the sky.
  5. Morela’s back at the nest 2:03pm-3:32pm, for about 90 minutes, but she looks sleek and vigilant, not egg-y at all.
  6. Ecco returns for 90 minutes, 5:29p-6:56pm.
  7. Neither bird is at the nest after that.

The photos are numbered to match what they illustrate.

#1. Morela is on the roof during the early morning hours of 21 March.

#3. Ecco has bright orange beak and legs.

#3 and #5 Morela’s beak and legs are yellow, not orange. At 2:00pm she looks sleek and vigilant, not egg-y at all.

#4 Ecco stops in briefly and watches the sky.

Neither bird is at the nest today which indicates again that there’s probably a challenger.

Fingers crossed that the intruder is driven off soon. Go, Morela!

UPDATE on Morela and Ecco as of Friday 24 March 2023, 5:50 am:

  • Morela’s most recent appearance at the nest: Tues 21 March at 3:32pm.
  • Morela last seen: Vigilant on Heinz Chapel scaffolding Wed 22 March at 4:14pm.
  • Ecco last seen: Watchful at the nest, Thurs 23 March at 5:13pm.
  • The Challenger: Has not been seen yet (which is good news).

My conclusion from these sightings: The challenger is female. Morela is keeping her away the Cathedral of Learning but has not vanquished her yet. The challenger has not won either.

Waiting For An Egg

21 March 2023

For almost a week Morela has looked as if she’ll lay an egg any minute at the Cathedral of Learning peregrine nest. Yesterday morning we thought she was ready. She lumbered off the green perch and stood in the scrape. We watched and waited.

But minutes later Ecco showed up with a snack. Morela didn’t tell him “Go away I’m busy.” Instead she got up to grab it and eventually left to eat. As Ecco steps up to watch her leave, he realizes he has fluff stuck to his toes.

This morning at 6:54am there is still no egg. So we’re still waiting.

Morela, of course, is waiting more than any of us.

Will she lay her first egg today? Stay tuned the National Aviary Falconcam at the Cathedral of Learning.

UPDATE, 22 March 2023: See this article about a possible challenger.

Bow and Sashay at the Nest

3 March 2023

This morning we may be two weeks away from the first Pitt peregrine egg of 2023. Morela’s first egg in 2021 was March 17, last year it was March 18. But who knows? She could be early or late this year.

Yesterday the pair had three bowing sessions at the nest. The first was brief and initiated by Ecco. The second was longer and Morela stuck around to dig the scrape. The third was unusual: Morela spent the entire time on the nestbox roof while Ecco bowed below. Did you see her yell at him from the roof? Check out this photo.

When the pair is not together one of them may be on the green perch, stepping in a sideways sashay. (This sashay video repeats the steps for emphasis.)

While you watch the falconcam get some practice identifying the birds with the two-photo slideshow at top. Notice that Ecco is small, has brighter-white and darker-gray feathers (more contrast), and has bright orange skin on this face and legs. Morela’s feathers are duller with less contrast, she’s bigger, and she has a peachy chest.

23 February 2023

Peregrine falcons in southwestern PA are preparing for the nesting season by conspicuously claiming territory and courting mates. Here’s a roundup of recent peregrine news plus a regional map of known sites. Notice the dates. If you want to see a peregrine falcon, now is the time to do it!

Peregrine locations in Southwestern PA (annotated by Kate St. John)

This eBird map of recent sightings shows that peregrine locations are skewed north of the City of Pittsburgh. There may be peregrines south of Pittsburgh but we need observers along the Monongahela River.

Cathedral of Learning, Univ of Pittsburgh:

Morela and Ecco have been staying close to home at the Cathedral of Learning and visiting their nestbox every day. The easiest way to see them is “live” on the National Aviary falconcam, video below.

If they’re not on the falconcam check all the perches at the top of the building (area highlighted above). Peregrines somehow manage to match the building so you’ll need binoculars.

Last year Morela laid her first egg on 18 March. When will her first egg appear this year?

Downtown Pittsburgh:

Will the peregrines use this location in 2023? (photo by Kate St. John)

Montgomery Brown reports the Downtown peregrines in eBird from a vantage point at One Oxford Center, most recently on 8 Feb. Have peregrines shown up at the 3rd Avenue nest site yet (photo above)? More observers needed!

UPDATE on 24 Feb 2023: Jeff Cieslak photographed a peregrine perched at the 3rd Avenue nest ledge as seen from Mt. Washington.

p.s. Are any peregrines at the Gulf Tower? No. Peregrines have not used the Gulf Tower site since 2017. Observers in the building will let us know if the peregrines show up.

Monaca RR Bridge, Ohio River:

Dante Zuccaro reports one or two peregrines almost every day at the Monaca Railroad Bridge as seen from the mouth of the Beaver River. Check the bridge closely. This pair is very reliable but hard to see. Jeff Cieslak’s photo is from 9 January.

Ambridge-Aliquippa Bridge, Ohio River:

Ambridge Bridge, 20 Feb 2020 (photo by Kate St. John)

This winter Mark Vass periodically has seen one or two peregrines at the Ambridge-Aliquippa Bridge, most recently on 20 February. In five years a nest has never been confirmed.

Sewickley Bridge, Ohio River:

Peregrine on the Sewickley Bridge, 9 Jan 2022 (photo by Jeff Cieslak)

On an errand in Sewickley yesterday I saw one peregrine atop the Sewickley Bridge. A pair was seen as recently as 11 February. Keep an eye on the Sewickley Bridge in case the peregrines decide to nest there.

Eckert Street near McKees Rocks Bridge, Ohio River:

While on Ohio River Boulevard yesterday I saw a peregrine perched on the power tower near Alcosan thanks to the McKees Rocks Bridge stoplight. The tower is a favorite hangout of the Eckert Street Bridge peregrines who raised four young last spring.

Jeff Cieslak often visits the Eckert Street territory and provides this map of places to see the peregrines. His “Ohio River Boulevard” arrow points to Eckert Street.

The Westinghouse Bridge peregrines have become more visible as they ramp up to the nesting season. Dana Nesiti stops by to see them when he gets a break from photographing the Hays bald eagles. This pair is easy to see before the female lays eggs in mid to late March.

Tarentum Bridge, Allegheny River:

The Tarentum Bridge peregrines are very conspicuous lately and seen by many observers. In Dave Brooke’s photo above, the female is perched on the navigation lightpole with a full crop.

Graff Bridge, Rt 422, Kittanning, Allegheny River:

This winter Theo Rickert has been checking the Graff Bridge near Kittanning with good success and reported two peregrines on site on 19 February. This nest site is probably used every year but sometimes no one notices. Thank you, Theo!

No recent news: There’s been no news since last year from three sites.

Clairton Coke Works: This nest produced three young last year but it cannot be seen outside the premises. We await news from USS employees at Clairton Coke Works.

62nd Street Bridge / Highland Park Bridge / Aspinwall Riverfront Park, Allegheny River: There are 3 bridges to check in close proximity, any one of which might have a peregrine family. Take a look and tell me if you find a peregrine.

Speers Railroad Bridge, Washington County, Monongahela River: No news from this site for over a year. Observers needed!

Additional bridges to watch: Peregrines love to perch on top of bridges. Check these out!

  • West End Bridge, Ohio River.
  • Bridges at Downtown Pittsburgh over the Allegheny and Monongahela Rivers including Roberto Clemente (6th), Andy Warhol (7th), Rachel Carson (9th), Smithfield Street
  • 40th Street Bridge, Allegheny River

Preparing The Nest

Ecco and Morela bow at the Cathedral of Learning nest, 20 Feb 2023 (phot ofrom the National Aviary falconcam at Univ of Pittsburgh)

21 February 2023

Even though Morela won’t lay eggs until mid March, the peregrine falcon pair at the Cathedral of Learning are actively courting and preparing their nest. Yesterday they bowed for several minutes and dug the scrape.

Peregrines don’t build stick nests. Instead they lay eggs in a bowl that they scrape in dirt or gravel on their chosen cliff ledge. The bowl prevents their eggs from rolling off the cliff and shelters the eggs while they incubate. The nest is the bowl; it’s called a “scrape. “

In late February and early March the Pitt peregrines spend ever longer periods at the nest, together or separately. Yesterday morning Ecco called Morela to come join him. When she didn’t arrive he dug at the scrape.

By 10am Ecco had convinced Morela to bow with him. Notice how they nearly touch beaks.

After their bowing session Morela went through the motions of digging at the scrape, then stood in it a while. Maybe she was thinking of the day she’ll lay an egg.

Every day Morela and Ecco are spending more time at the nest. Watch them on the National Aviary falconcam at the Cathedral of Learning.

Distracted Courtship

7 February 2023

The months of February and March are some of the best times to see peregrine falcons (Falco peregrinus) in southwestern Pennsylvania as the birds ramp up their courtship rituals and become more visible.

Pitt peregrines Morela and Ecco visit their nest more often at the Cathedral of Learning, but in this early stage of courtship they are easily distracted. Yesterday the male, Ecco, bowed and called at the nest for five minutes (a high whistle sound) before Morela would even look at him.

The video begins just before she starts to pay attention. Morela looks at him and responds with a gravelly “e-chup” but Ecco is distracted by material in the corner of the nestbox. In the space of two minutes they pay attention to each other, and then they don’t.

By the time Ecco leaves the nest, he’s distracted and Morela is focused.

Watch the Pitt peregrines “live” on the National Aviary falconcam at the Cathedral of Learning. We expect Morela to lay eggs in mid March.

Meanwhile look for peregrines at a nesting site near you, listed below with updates current to the date at top right.

The Pitt Peregrine Falconcam Is Up!

1 February 2023, 4:30pm

Today the National Aviary’s Falconcam began streaming the 2023 peregrine nesting season at the University of Pittsburgh’s Cathedral of Learning.

Ecco and Morela are already courting so if you’re lucky when you tune in you’ll see them bowing and touching beaks as they do in this video from February 2021. When they bow they make soft noises to each other. Morela’s voice is gravelly (she’s larger). Ecco’s voice is a whistle-squeak (He’s the small one.).

On Finding Pellets

22 January 2023

This red-tailed hawk is not consuming the lump near his mouth. He’s casting a pellet of indigestible bones, fur and feathers that came up from his gizzard. Pellets are a normal by-product of digestion in birds of prey. If you find one, it can tell you what the bird was eating.

We always find pellets during annual maintenance at the Pitt peregrine nestbox including these three found during our 9 January visit (paperclip for scale). The pellets can be many months old.

A closeup shows feathers and bones (no fur*) but is not very enlightening due to the pellet’s age. Fortunately I stored the pellets in a ziploc bag. After they thawed a small fly appeared inside the bag, hatched from eggs laid on the pellet in much warmer weather. Ewww!

Closeup of peregrine pellet (photo by Kate St. John)

I imagine the pellets came from Morela since the green perch is one of her favorite places to rest and digest.

Peregrine pellets are slightly longer than a paperclip. Some birds make much larger pellets.

On a hike at Audubon Greenway Conservation Area last Wednesday we found a surprisingly large pellet containing fur, bones and a big tooth. It was so large that we wondered if a bird could produce it. I didn’t pick it up but it looked as though it could span my palm.

A Google search revealed that great horned owl pellets are 3 to 4 inches long, usually cylindrical and tightly compacted. This one may have opened up because it was soaked by heavy rain.

So what did the owl eat? Whose big tooth was that?

Learn more about owl pellets at The Owl Pages: Digestion in Owls.

* p.s. There is no fur in peregrine pellets because they don’t eat mammals, only birds.

Up To The Rooftop

21 January 2023

Peregrine news at the Cathedral of Learning is pretty quiet lately.

Morela did not stop by the nest yesterday but Ecco visited a couple of times including a surprise approach to the snapshot camera.

His favorite way to leave was by jumping to the roof.
