I did a Chimney Swift count at Woodley Hills Elementary School in Fairfax
County (very close to Mt. Vernon) last night. Between 8:03 and 8:14 pm, I
counted 201 birds entering the chimney.
The highlight was a Coopers Hawk that came out of nowhere and scattered the
swifts. I don't think the hawk got anything, but all of the swifts completely
vanished! After about 30 seconds, half the birds returned, but it was
probably around 5 minutes until they all came back.
