FYI regarding the Chimney Swift numbers:
Greater Ozarks Audubon Society members counted the following in Springfield, MO:
Saturday, September 7: rough count of 1113 birds in two towers at a local apartment complex.
Tuesday, September 10: approximately 900-1000 swifts in one tower in the downtown square area of the city.
Friday, September 13: approximating the same number (?) as Tuesday.
Since there are multiple large chimneys in the downtown area, some were estimating that perhaps 2000 swifts were entering multiple towers.
