Type 2 flight calls. Edits: trimmed and normalized to -3 dB. Uploaded 2017 Sep 25.
観察結果の詳細
Audio recording. Seen briefly and only in flight. Identified as type 2 red crossbills by generating an audio spectrogram and comparing the flight calls with those depicted in Groth (1993), Irwin (2010) and Young (2012). Flight call type verified by Matt Young at the Cornell Lab of Ornithology. At least two type 2 flight call variants are evident on the recording. The type 2 flight calls were much more emphatic and louder than the type 6 calls we heard (and recorded; see below) a short time earlier. The audio spectrogram shows vocalizations from at least three birds but there could easily have been more.
