Observation details
Crude estimate based on photos and videos; photo which captures 1/4 to 1/3 of flock has ~140 swifts. A video of swifts entering captures about ~250 (counting by 10s) entering in 37 seconds. The video does not capture the beginning. It ends as activity tapered off , but there were easily another 150 in next wave plus stragglers.
