影音備註
Apparent Cassia Crossbill and Red Crossbill in flight, both calling. Cassia Crossbill is the lower pitched of the two call notes.
觀察細節
Apparent Cassia Crossbills known to be present in the area since 17 July 2022. Two birds heard in distant flight and a third was perched and calling from a pine near the trail for a minute or so before I observed it fly to the east. None of these birds could be seen clearly and the one I did see was in silhouette only. One recording is of a single bird perched and the second appears to be a Cassia Crossbill and Red Crossbill together in flight (the Cassia is the lower pitched of the two).
