The only way to see into the Downtown peregrine nest on Third Avenue is to observe it from Mt. Washington. Yesterday Lori Maggio took long range photos from the overlook and saw Dori, some chicks and Dori’s mate!

Here are her photos and observations:

I looked this afternoon between 1:30 and 2 pm and saw both Dori and the male in the nest and what I believe was Dori feeding the chick(s). When I first got up there I could only see Dori and what I believe a chick under her.  When I looked a few minutes later I saw both adults.  He was standing at the opening of the nest and it appeared as though Dori was feeding the chick(s). I imagine he brought the prey to her.  After a few minutes in the nest he flew out.  So it appears that she and her mate are raising at least one chick.  I have included some pictures and one of what the nest site looks like empty so you can compare.

For comparison, here’s the nest site at other times of year when there are no peregrines nesting in it.

Yay! There are peregrine chicks Downtown!

Thank you, Lori, for the photos.

Yesterday at the Cathedral of Learning peregrine nest, Morela incubated her eggs most of the time but took breaks in the morning and afternoon. This timelapse video gives you an idea of much time she spent on the eggs.

At 9:03am Morela stood up and bowed to an unseen male peregrine who was out of camera view. He never came down to the nest.

In the 6 o’clock hour Morela called but neither Terzo nor Ecco showed up.

Incubation was intermittent and no mate arrived to help. With this sort of treatment, Morela’s eggs are not going to hatch.

Everyone was surprised when Morela laid a second egg yesterday at the Cathedral of Learning peregrine nest and appeared to start incubation. It was a week since she laid her first egg and it’s unclear if either male, Terzo or Ecco, will assist in incubation. Are the eggs likely to hatch?

Fertile eggs will hatch if they are kept at the right temperature — constantly — for the right amount of time. Once the eggs’ temperature is raised by the skin (brood patch) of the parents laid against the shell, the embryo starts to develop into a chick. If the temperature is not constant or it does not last for the right number of days the developing embryo dies.

Delaying the start of incubation is a normal strategy for many species. Ducks, shorebirds and peregrine falcons wait to start incubation until the clutch is (nearly) complete. This is not harmful to the early eggs as long as they are kept from freezing and moisture.

However, once incubation starts it must not stop until the job is done. Uncovering the eggs for more than a few minutes, depending on outside temperature, is fatal because the developing embryo is too far along.

So when Morela appeared to incubate for several hours yesterday (see video) and then stopped overnight, the chances for her eggs dimmed.

The real test will be whether her incubation efforts are constant and whether Terzo or Ecco help her. It takes a pair of peregrines to raise a family. If no male helps incubate, the eggs won’t make it.

16 May 2020:

At 2:15pm today Morela laid a second egg at the Cathedral of Learning peregrine nest. It’s been a week since she laid the first egg on 9 May so this is quite surprising. Peregrine falcons normally lay eggs about 2-3 days apart.

This five minute video captures the moment she laid the second egg, though it’s hard to see it.

Soon, Morela appeared to start incubation. She deepened the scrape, positioned herself over the eggs and jogged her body so her belly feathers could fall away from her brood patch. Then she laid flat on the eggs.

This activity was short lived, however. By 4:15pm she had left the nest.

Who knows what will happen next. If she incubates the eggs will a male assist her? And if so, will it be Terzo or Ecco?

Since his arrival at the Cathedral of Learning in late February, Ecco has always spent more time on camera with Morela than the resident male peregrine Terzo. Whenever they’re at the nest, Morela and Ecco court and bow for 3 to 8 minutes while Terzo visits for 15 seconds if we see him at all.

Ecco usually has to be persuaded to visit the nest, but on Wednesday 13 May he initiated courtship that lasted nearly three minutes.

It appears that Terzo is fading into the background while Ecco is becoming more established.

Too bad Terzo and Ecco didn’t sort this out in February!

13 May 2020

Since late February two male peregrines, Terzo and Ecco, have been vying for the Cathedral of Learning and Morela’s attention. When she finally laid an egg in the wee hours of 10 May we were — and still are — full of questions: Who’s the father? Are both males still present? Will Morela lay another egg? Will this egg hatch?

The video below of Morela and Ecco on Sunday 10 May, 1:18p, provides a few answers. In it, Morela encourages Ecco to come bow with her at the nest. He joins her and bows but is obviously distracted and warily watches the sky. Morela tries to attract his attention. They exchange a glance. She gives up and leaves.

In the clip you can see that Morela’s crop is full. Since she’s bowing with Ecco just after eating, my guess is that he provided the food.

Ecco is really distracted and appears to be looking for a rival, not for a predator that threatens the nest. Terzo shows up 20 minutes later (1:38p-1:43p).

Will Morela lay another egg? I doubt it. She has passed the 2-3 day window when a new egg should appear. More importantly, egg production depends on the amount of attention she receives from her mate and she needs a lot of it. Ecco and Terzo are too busy to pay attention.

Will this egg hatch? No. It takes two dedicated peregrines to incubate the eggs and raise the chicks. Without a male taking his part in incubation, the egg will not to hatch. Morela knows the males are too distracted.

“Excuse me, my dear, while I check the sky.”

While “Who’s the father?” soap opera unfolds at the Pitt peregrine nest, other sites are raising chicks. Here’s the news from other peregrine families in the Pittsburgh area.

Westinghouse Bridge:

When Dana Nesiti brings his camera to the Westinghouse Bridge, he hopes to capture the kind of peregrine action he saw on Sunday 10 May. The male brought food to the nest from a nearby cache area. Then the female harassed a Cooper’s hawk in aerial combat. Here’s a slideshow of Dana’s photos.

Tarentum Bridge:

The peregrines nesting at the Tarentum Bridge have been bringing food to the nest for a couple of weeks though we can’t see the chicks. Yesterday, 11 May 2020, Susan Krause reported that a fluffy white chick appeared at the front of the nest. The chicks are walking! This means they’re at least two weeks old. They probably hatched around 27 April.

Visit the Tarentum Boat Ramp for a good view of the nest area. To see the front of the nest, stop near the river access at the corner of Wood Street and East 1st Avenue or watch from Tarentum Riverview Memorial Park.

Downtown Pittsburgh:

Because of the COVID-19 shutdown Lori Maggio has not been Downtown so she’s watching from Mt. Washington, though infrequently. On Sunday 10 May she may have seen some white blobs (chicks) in the nest without adults. This would mean the chicks are pretty big and old enough to thermo-regulate. Dori has historically hatched eggs between 19 April and 2 May so these chicks may be the same age or older than the ones at Tarentum. Lori will check later this week to see if they are more visible.

For almost three months I’ve been watching and writing about the new unbanded male peregrine at the Cathedral of Learning. He hasn’t won the site from Terzo but his presence has thrown the nesting season into a tail spin. I’ve called him “the new guy” but he’s not new anymore. And he’s still here. It’s time he got a name.

Our peregrine naming tradition in Pittsburgh means that I’m the one who names him (details here). It’s a difficult process and I’ve messed up in the past so I’ve been reluctant to go through this. I thought he’d go away, but here he is.

“Here he is” (Eccolo in Italian) inspired his name. His name is Ecco.

Ecco means “here” or “there” in Italian but is often used at the beginning of sentences to get them rolling as in “Well” or “OK” or even “Hey” as in “Hey, that’s what I thought too.” Here are three descriptions of ecco: Word Hippo, Colloquial Italian blog, Italian-English at Cambridge.org

The fact that Ecco is pronounced “echo” is also apt. This bird shows up repeatedly, like an echo, even after we thought he was gone.

So here is Ecco, calling, pondering and watching the sky, plus two videos so you can get to know him.

Ecco’s first appearance on camera, 28 February 2020.

Ecco visits the nest and calls to Morela, 9 May 2020.

It’s convenient that both males have names now.

I don’t think Ecco is going away anytime soon. Nor will Terzo.

10 May 2020

Welcome to the strangest peregrine nesting season I’ve ever seen at Pitt’s Cathedral of Learning. Since late February an unbanded male has been challenging Morela’s mate Terzo for ownership of the Pitt nest. Neither male has won and the contest continues, so when Morela didn’t lay eggs by the end of April I thought she never would … until she laid one at 12:42am on Saturday 9 May.

Here’s the moment the egg appeared. (Thanks to Bev Fullbrandt for reporting the time.)

Naturally we wondered, “Who’s the father?”

For peregrines, the biological father doesn’t matter at all but an active participating father is key to egg and chick survival. The male provides food from courtship through brooding, shares incubation duties, and hunts for the entire family after the eggs hatch. A solo female will eventually abandon her eggs if her mate does not return.

Morela has the opposite problem but I figured we’d learn which male is the active father by watching who showed up to examine the egg. They both did.

Terzo visited from 1:38 to 1:43pm on 9 May.

Ecco, the new unbanded male, made several visits in the 5pm and 6pm hours and bowed with Morela.

Here’s a video of his first two visits: 5:38pm and 5:47pm.

Meanwhile, who is feeding Morela? Who will incubate the eggs? Will there be more eggs?

We still don’t know what’s going on, but with your help we’ll find out. Watch the National Aviary falconcam at Univ. of Pittsburgh and let me know what you see.

A big Thank You! goes out to everyone who’s left comments on the activity at the nest. Keep up the good work! It’s much appreciated.

p.s. What an unusual title for Mother’s Day!

Oh my goodness! At 3:40am Michelle Obosky left a comment on the blog:

Did you see the egg ? at the nest. I saw it this morning May 9 at 3:39am. Maybe I’m crazy

Michelle, you’re right! It’s an egg! Morela’s first. It looks white snapshot of the infrared light.

She laid it at 12:42am on Saturday 9 May. (Thanks to Bev Fullbrandt for reporting the time.)

Here’s another glimpse in a video from 3am.

With the ongoing contest between Terzo and the new guy I’ll admit I’d given up on any eggs this year. This is such great news!

Watch the National Aviary falconcam at Univ. of Pittsburgh for more developments. Be sure to watch for her mate to come see the egg. I don’t know who it will be.

Oh my!

p.s. It is probably above freezing in the Cathedral of Learning nest. The lowest temperature in my city backyard last night was 33 degrees at the thermometer away from my house.
