many seen well, a few photographed poorly (photos above); no other species of swiftlet seen in the flock despite intensive observation from 1510-1540. It is possible that one or a few of some other species of swiftlet were present and overlooked but unlikely

Individual Characterization

Behaviorrepeatedly flying back and forth in open area above hilltop; sometimes coming very close to me, but nevertheless I got notes on only one of several attempts, so they are silent much of the time even when swooping down at close range
Group sizesmall loose flock
