Carla laid her fourth egg at the Cathedral of Learning at 10:25a this morning, 56.4 hours after Egg#3. Most of us didn’t realize it happened. Thanks to Laurie Kotchey’s sharp eyes and her comment on my blog, I knew to start looking for Egg#4 when I got home at 11:30a.

The video below shows the egg-laying moment, sped up to double-time, but you won’t see the egg itself because Carla is facing the camera. Instead, watch her behavior. She eventually stands tall, opens her beak and points it upward. Wait for the moment when she bows down and raises her tail as she lays the egg.

I believe this is Carla’s last egg for the year because she has already started incubation. More about incubation in an upcoming article.

  1. Happy 4th egg for our resident PEFAs at the Cathedral.

    A question for you, Kate. Do Carla’s vocalizations sound different to you, kind of raspier or lower in tone, from other females we have had the pleasure to watch on camera? Not sure I can really describe the difference; do you hear something different, too, or is it just me? Thanks for your thoughts.

    1. Pa Gal, I have noticed that Carla makes interesting sounds when “talking” to Ecco. In this article I included a video of an overnight nest exchange and said “Carla woke up and responded with unusual squeaky chirps.” https://www.birdsoutsidemywindow.org/2024/03/17/second-egg-and-overnight-nest-exchange-at-pitt/
      Each female at the Cathedral of Learning has been unique. I much prefer Carla’s soft squeaks to Hope’s shouting! https://www.birdsoutsidemywindow.org/2017/03/17/why-is-she-shouting-and-other-news/. Gosh, that was 7 years ago.

  2. Thanks, Kate. Hope was quite the shouter, wasn’t she!? I’d forgotten that. How time flies, how could it be 7 years ago.
