Last night (September 12-13, 2010) between 11:15 PM and 6:15 AM the microphone on the roof of my house in Cleveland Heights detected over 400 thrush calls. I believe that the majority of the calls were Swainson's Thrush (probably 80% or more), and most of the rest Gray-cheeked Thrush, with a Veery or two thrown in. This morning at the Nature Center at Shaker Lakes (about 3/4 miles southeast of my house) Julie West banded 16 Swainson's Thrushes and two Gray-cheeked Thrushes. I also detected a much smaller number of higher frequency (probably warbler) calls, but these are much harder to pick up and sort out, and I did not attempt to count them.
