Подробности наблюдения
Several flocks of crossbills in the area with multiple birds flying to the ground to visit the dirt patch across the stream from the ski houses (presumably to eat minerals or gravel). Compared to the Cassia Crossbills seen around Diamonfield Jack these seemed smaller-billed and had higher-pitched calls. Looking at the spectrograms the call notes have a different shape from CACR (see recordings filed under type 2). A large flock that I felt reasonably confident were type 2 I've assigned to that group in the checklist, others I've left as RECR (or Red/Cassia if non-vocal).
