I just got back from Swift Night Out with the Baltimore Bird Club. It was quite a sight: we saw 3,090 Chimney Swifts!

The evening began with thousands of swifts circling around the chimney at the Book Bindery. Then, at about 7:25 p.m., the first one dove into the chimney. Then, they went in spurts: a few hundred would dive in, they’d all circle around some more, then another set would dive in. I forgot to look at my watch when it was over, but I think they got into the chimney in less than half an hour. Pretty amazing!
