Détails de l'observation
ID based on audio spectrograms. Flight call is lower pitched (below 4 MHz) compared to other local crossbills (types 2, 4, 5). Spectrograph shape matches Cassia flight call. These birds were foraging on pine cones of recently cut pines in a slash pile in a clear cut section of Lodgepole Pine Forest along forest road 516 (both sides of road) about three miles east of Colorado state highway 125 just south of Wyoming border.
