Nocturnal flight calls
11 April 2006- Caroline, Tompkins Co., New York- description:Recordings made around 0455. First recording unfiltered, second recording filtered. These 2 examples come from a series of 8 vocalizations recorded between 045549 and 045627 (8 vocalizations in 38 seconds). Unfortunately, the bird was at some distance, and there was some aberrant noise. Consequently, the spectrograms are not clear, and headphones are needed to hear the calls.
