Tessaglia-Hymes" <c...@cornell.edu<mailto:c...@cornell.edu>> During the morning descent of thrushes calling, I was pleasantly surprised to record another nice example of a BICKNELL'S THRUSH flight call. This bird called at 6:29AM. This bird's call peaks out at about 5.23kHz, well above any Gray-cheeked Thrush NFC that I've seen. Most of the Gray-cheeked Thrush flight calls that I have recorded, peak out in the 3.5-4.5kHz frequency band, with a very occasional call that might peak out every so slightly above 4.5kHz. The overall duration of this call is shorter than the one from the other night, this lasting only 208ms. The quality and timbre of the call is likened to a much higher-pitched and wheezy-sounding "Gray-cheeked Thrush". An edited copy of the call is attached, again to remove the cricket band and slightly amplify the sound. A screen grab of the call is also attached. Good night listening!
