Observation details
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).
