At the Cathedral of Learning peregrine nest, Carla is getting closer to egg laying. Her actions in the past week have been very promising.

A month ago Carla was mildly interested in courtship. Her mate, Ecco, would beg her to come bow with him. It sometimes took several minutes before she would join him and she always left the session before he did. This week Carla is in the mood.

On 4 March, for the first time this season, Carla stayed at the nest after the bowing session when Ecco leaves.

On 6 March, Carla initiated the courtship session.

On 7 and 8 March the pair stepped up their courtship frequency, engaging in four bowing sessions per day on Saturday and Sunday. Sunday’s four sessions are shown in single snapshots below.

Over the winter when we saw a bird at the nest it was always Ecco. Now it is Carla who spends many hours at the nest. This timelapse video from yesterday, 9 March, condenses her three hours into two minutes.

And finally, the best sign of all is that Carla has been spending the night at the nest. Here she is roosting this morning at 5:01am with her beak in her back feathers.

For a wider view of the green perch, see the National Aviary snapshot camera.

Watch for Carla’s first egg, probably in the next week, at the National Aviary falconcam.
