No Chimney Swifts visible - just the habitat (roost chimney), satellite view, 215 S McDowell St, Raleigh, Wake, NC. Note the small hole compared to the large chimney; it's amazing that they pour into this so rapidly!
Detalles de la observación
Conservative estimate, based on counting 100x100 of swirling flock. The swifts entered the chimney at 215 South McDowell (News & Observer) from 7:14 until 7:30. About 10 per second entered the chimney over a period of 15 minutes. There were breaks in between where they were swirling, so another estimate was based on 500 birds entering the chimney per minute for a total of 7 active minutes. They started the entry at 7:14 and the last bird entered at 7:30.See photos.
