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.
