Yesterday morning I was surprised to learn that a new male peregrine was at the Cathedral of Learning nest last Thursday, 27 February. After much research I’ve discovered that …
Terzo and an unbanded peregrine have been vying for the Cathedral of Learning nest for at least a week. The contest is ongoing and there is no clear winner yet. Sometimes Terzo is at the nest, sometimes it’s the new guy. Here’s what has happened so far:
24 February, 3:40p: Terzo rules. As proof, he and Morela bow at the nest for about five minutes.
25 and 26 February: For two days there is almost no activity at the nest, indicating that the peregrines are busy with other concerns. Morela makes four short visits alone. During her last visit on 26 February at 11:47am, she bows to a peregrine off camera who never appears.
27 February, 3:44p: New unbanded male peregrine at the nest. He and Morela bow for three minutes.
Friday 28 February 2020 is a back and forth day. Terzo rules at dawn and dusk. The new male bows with Morela at 1:07pm. Three photos below.
28 February, 7:00a: Terzo bows briefly with Morela before dawn.
28 February, 1:07p: New male courts Morela for seven minutes. See the video here.
28 February, 5:42p: Terzo is back at dusk.
29 February: Terzo is still in charge. He bows with Morela for two minutes at 7:33a.
1 March 2020: Inconclusive! The peregrines spend so much time away from the nest that they don’t notice when two ravens soar over the Cathedral of Learning and swoop near the nest at 11:07a. Ravens are very unusual on campus and would have been chased away by the peregrines … if they’d been at home.
In the afternoon, Morela spends less than half an hour at the nest. Twice she bows to a peregrine off camera.
Today, 2 March 2020, 7:35a: Terzo rules. Morela visited the nest twice before dawn and bowed to an unseen peregrine. Then Terzo visited the nest alone at 7:35a.
The contest is still in progress. Watch the National Aviary falconcam at the Univ of Pittsburgh to see what happens next!
