I’m amazed to see the Chimney Swifts still roosting in large numbers at 944 Fifth Avenue.  I would have expected the number to have decreased by now.  What’s been fascinating to watch is the change in behavior.  Instead of swarming at the model boat pond and then going to the roost, lately the swifts have been appearing almost out of nowhere five minutes before they roost.

It would be fascinating to know if they are swifts hunting higher or in a different place during the day or if these are migrating swifts that know this stop along their migration route?

Update: I went to see them on Thursday, October 22nd and only saw one Chimney Swift at the roost. It made one pass at the chimney and continued on.
