On August 21, as the eclipse neared its darkest point, I noticed a dozen Chimney Swifts swooping low over our yard, twittering very excitedly. As it got darker, the swifts began perching (!) in the tallest bare branches of a tall pin cherry tree, and their numbers increased. At the darkest point, my wife Marcia and I counted 25 swifts. This is the highest number recorded ever in our yard. as the light increased, the swifts vanished. I dont think I had ever seen any number of swifts perching on branches- didnt know they could do that!
I surmise they were migrating, or just out hunting, when the eclipse darkness caught them by surprise and they set down at "first dark" when unable to reach their preferred chimney.
