natural vocalizations; begging calls from unseen nestlings given when a female flew in with food. The nest was located in the middle of a fairly steep cliff mixed with lots of talus. I wasn't able to approach the nest while recording, but went back the next day and found it predated. Examination of the feather remains showed that the nestlings were well feathered but not yet capable of flight.
