觀察細節
all were seen to enter the chimney in groups of no more than five, it didn't appear that any had entered before I arrived as I had to wait for the birds to show up, it was about five after nine that the first swifts circled the chimney and they were all tucked in by 9:12, I waited another four minutes and didn't see or hear more swifts so I left to pick up Harold Forsyth who was observing at the Robie Tufts Nature Centre. (no CHSW entered the Nature Centre chimney on this night)
