We arrived at the Bristol
School on Gray Av in Webster Groves at 7:20 PM and the Swifts were
gathering in large numbers, probably more than last night. A thunderstorm
was approaching from the west and seemed to cause them to fly more erratically,
sometimes clockwise over the school and then counterclockwise. Two raptors
tried to take a meal from the gathering swifts, one looked like a small falcon
that went right into the flock and then was chased off by a group of the
swifts. The second raptor looked more like a Coopers hawk and stayed
above the flock of swifts.
The swifts were all into the south chimney by 7:35 PM.
The entire flock went into the chimney much faster than last night.
