Signs today finally suggested that egg(s) had hatched had occurred at the red-tailed hawk nest at the Cathedral of St. John the Divine, and that it probably happened several days ago. When I first arrived there early this evening, one adult was perched on the edge of the nest, halfway keeping an eye on the interior. The other flew up a minute later, there was a short confab.
And then the first took off.
The second kept an eye on things for about five minutes and perhaps fussed about inside the nest for a moment before also taking off. The nest was then left unattended for 25 minutes, aside from about a half minute of one of the parents briefly perching on the statue of St. Gabriel up on the rooftop.
Isolde returned about a quarter to seven, spent a minute eyeing the situation.
And then settled down in the nest.
Although this was a pretty warm day, the long period in which the nest was unattended suggests that all the nestling(s) in there are more than a day or two old. Hawkwatching along Morningside Drive should start getting more interesting during the next week.
