It was another strange night at the Gulf Tower peregrine nest in Downtown Pittsburgh.
As I mentioned yesterday, Dori and Louie were active the night before, unexpectedly on and off the nest. Then yesterday afternoon I received a clue. Barb Becker at Make-A-Wish told me that Louie and Dori were both at the nest when a third peregrine wailed in the distance. Hmmmmm! Sounds like Tasha is still in town.
This morning I checked last night's video archives and saw that Louie incubated most of the night. It's highly unusual for the male to do this, so something odd must have been going on. Here's the sequence of events:
- At 1:25am Dori looked around. There was a high wail in the background. Who? Dori got up and left the nest. (00:20 in the archives)
- Within two minutes Louie "eep"d off camera and arrived to incubate the eggs. Other than this it was silent.
- An hour and a half later, Dori returned and asked to incubate the eggs but Louie would not get up. Dori stood at the nest near him for more than ten minutes but didn't force the issue. Eventually she left, shown above. (1:40 through 2:00 in the archives)
- Finally at 6:20am she returned and stood over him making a lot of noise. She seemed to be saying, "Get up!" Louie left. (5:20 archive)
These two are dutiful parents. The temperature dropped yesterday in Pittsburgh from the high 70's during the day to the 30's last night. Perhaps Louie knew Dori had some unfinished business that could take her away from the nest unexpectedly so he decided to incubate all night ... just in case.
