Note: Found adult sitting on ledge on arrival. 30 minutes later it flew to a ledge and I heard wailing, but not sure if it was this bird or not. After 15 seconds, it flew to a well used perch. After 20 minutes it flew to another perch in shade. After 20 minutes there, it flew off. @0 minutes later, I head wailing and found a bird flying across cliff face and landing at the same ledge. A second bird appeared from back of ledge and took off (female?). Male stayed on ledge and disappeared to back of ledge. Only had a fly over the last 2 hours. I think this ledge is the eyrie.
