As a graduate of Madison East HS (class 70) where we always made fun of the
towers and prison like architecture I am very happy to hear about the
incredible number of Swifts.
Go Purgolders!

Last night I stopped by East High School in Madison as dusk fell to check on
Chimney Swifts. I'd seen a few hundred using the central chimney over the
summer, but I was curious how many might show up during migration.
It was a pretty extraordinary flock, and hard to estimate while flying, but
as they began dropping in I started counting by fives as best I could, trying
to be conservative, only counting when the birds were stalling and dropping
straight. It took about twenty minutes and by the end (7:37pm), I'd
estimated about 1300 birds.
Given that it's possible that birds that looked like they were dropping in
actually moved past the chimney, and that my counts were off, I'm guessing
that the actual number is +/- a couple hundred.
Definitely worth checking out!
