At 7:25 PM this evening my wife and I were taking a
walk north on Gray Av in Webster Groves and
noticed many (500+) Swifts circling over the Bristol School.
At 7:30 they started going into the south chimney on the school and by
7:45 PM they were all in for the night. They maintained a large circle flying
clockwise over the school as a few at a time would drop down into the chimney.
Some of them chased off a crow that came nearby but then rejoined the circle.
We will check on them again tomorrow evening. This is the first time we
had noticed this event.
