10/9-10/16, 7:50 PM - 6:25 AM -- Yard, Westport CT An overall decent nocturnal flight this night. However, I recorded the following calls which I cannot identify. The recording 1.16.26 appears to be two calls directly next to each other - one at a middle-range kHz and the other very high. 3.52.46 appears to be a Lincoln's/swamp, but looks rather different on a spectrogram. 20.33.58 is around 6 kHz and is a straight, single-banded line, almost sparrow-like. 3.38.00 contains two 8 kHz "ticks" that are very clean and sharp. 3.03.20 is similar. 4.37.12 is a long call that has a very faint second ban. It sounds superficially sparrow-like. 5.00.06 is the most interesting of these calls. This call sounds similar to a goldfinch, and is double-banded. These bands are widely separated by a space around 2 kHz wide. At the beginning, the lower band starts at 4.5 kHz, and the upper at 10 kHz. Very strange.
