Chimney Swift entering roost chimney at 19:19 (last minute of a ten-minute entry)

觀察細節

Started out about 500 but kept increasing until time of entry into N&O chimney (directly west of our location). Estimate, increased rapidly between 6:50 and 7:05 pm EDT. A few entered chimney early but main flow began at 19:10 through 19:20 with heaviest infow at 19:15. One estimate based on 5 birds a second for 10 minutes.
