Примечания
Recorded at the Lassen National Park Devastation Area parking lot. The recording includes at least three variants of type 2 flight calls and "toop" calls (at 2.5 kHz). Other species: pine siskin and mountain chickadee. Edits to the file: trimmed and normalized to -3 dB.
Подробности наблюдения
We saw multiple flocks of red crossbills flying in the area. We also saw some very well feeding on cones in Jeffrey pines. I photographed a few including one juvenile. Vocalizations recorded extensively while the birds were perched and in flight. I used an Olympus LS-10 equipped with a Sennheiser MKE-400 short shotgun microphone. Vocalizations were soft and loud "gyp gyp gyp" calls. We have extensive experience with identifying RECRs by sound, but we also confirmed the identifications by seeing most of the birds using 8x32 binoculars. Sonograms generated using the Raven Lite software indicate that these were type 2s. Two recordings appear below.
