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.
