CoBirders, or maybe just Ted Floyd, Went out to check on some fixes I made to the gutters today and heard flight calls at 11:15PM. Rains had fallen within a half an hour and winds were out of the east at the surface, southeast at 850mb, and south southeast at 700mb. Good wind conditions for migration and the lowered cloud deck made the birds closer to the ground so I could hear them. I don't have the best night flight call ears... they are in fact rather new to it, but I did hear plenty of activity. Total of 279 calls in 35 minutes out on my patio in northwest Longmont. 271 were all the same species which I believe was Swainson's Thrush (slightly rising bree or breep). Other birds heard were Spotted Sandpiper (3), Chipping Sparrow (2), one zeep, a repeated chuh-dut, chuh-dut, chuh-dut, and 1 VEERY. The calls kept coming after I went inside, but it was time for bed, so I had to call it quits. I will be out in the morning to see what has arrived.
Hope others got a chance to get out and listen to some of this! Quite a phenomenon!
