Their social system just may be a complex one. After this I could not find a surfbird anywhere on or by that ridge complex. Neither saw nor heard any until I found a pair (2 birds) sitting very quietly on the SE slope of Center Hill acting like perfectly normal, pair-bonded birds. They were flying leisurely along the slope and were quite tame. They finally flushed and flew around toward the East slope of the same hill. 20 May Started up the road at 3:45 A.M. Reached Eagle Summit and climbed Puzzlemans Hill without seeing or hearing surfbirds, although other birds were active.

At 0630 found the birds - 3 of them again. Took the following sequence of notes: 0630 - 1 bird postures next to another. Wings sl. dropped; tail elevated
