In case you missed it at the Cathedral of Learning peregrine nest: Morela laid her first egg of 2021 on 17 March at 11:50am. (Time code on the streaming camera says 11:53a but that camera is 3-4 mins early.)

The timelapse video below gives an overview of the day’s activity: Morela, Ecco and the egg.

Details of egg laying: As the next video begins Morela was standing over the scrape but is restless. She paces and squats, then Ecco arrives to bow. He watches intently while she concentrates on laying the egg. After he leaves Morela pushes (raises tail), pants and lays the egg at 11:53:45am. Notice how she makes sure not to touch the egg while it’s wet. She moves to shelter it from the sun.

Father bird’s first visit: It is always interesting to watch the father’s first visit to the egg, especially since Ecco is a first-time dad. Ecco arrived at 1:20pm, chirped at the egg, turned it, dug the scrape deeper, and sheltered the egg from the sun. He is taking an active role in the egg’s welfare.

Do not worry that the parents are not “sitting” on the egg right now. Unlike bald eagles peregrines do not begin incubation until the female has laid her next-to-last egg — and only the female knows when that egg will be.

Until incubation begins both parents guard the eggs and shelter them but will not “sit” on them to raise their temperature. They will be nearby but maybe not seen on camera.

Morela will probably lay 3-5 eggs, one every other day. If her total is four, incubation may begin on or around 21 March. We’ll have to wait and see.

Watch the action on the National Aviary falconcam at University of Pittsburgh.

p.s. Terzo is gone, last seen on 5 Feb. Ecco is the only male on site.

  1. Does the fact that the egg is now being “incubated” mean that it will be the only one? 1:09p.m. March 18

  2. How long does a parent have to sit on the egg before it’s considered that incubation has begun? I tuned in at 12:40 and I think it’s Morela sitting on it continuously. (Don’t know how long she was on it before I checked in.) It’s now 1:20 (and I have to leave), and wondered if the egg is being incubated? Maybe she’ll only lay two eggs?

  3. Incubation begins when the birds open their belly feathers and lay the brood patch directly against the egg. It is very hard to tell what the belly is doing from our on camera view. Rest assured that the peregrines know what they’re doing.
