/ April 22 / which may have been the same individual I saw earlier and leave the second nest. We collected the nest by pulling the pine over with a rope. Inside were 2 eggs or 3 nestlings, probably a week or more ago. They gave a few soft "peep" notes when handled and seemed definitely repelled by light as they attempted to get the head under cover of some sort whenever we set them out in the open.
Best guess is that ♂ 2090 and ♀ 2088 were parents of these young. We may have collected birds other than those associated with the nest in the series of eight birds (# 2084-2091) but many were collected at the nest tree and doubtless belonged to this one group.
√ Apparently, the first nest we found (located in a broad-leaved tree - see plant collection) served as a roosting place for many of the 8 birds of the area while the other was used by one pair to raise their young.
√ Another nest a few hundred yards up (east) the canyon: Collected 6 birds (Nos. 2092-2097) in immediate vicinity of the nest. Took several photos (B.& W., Roll # 20) of the nest area. Walked up the hill through a rich forest of giant pines & oaks heavily covered with large epiphytes. In one spot I saw - at least 16 were together (but possibly in two sub- groups) calling excitedly. Collected two from this group.
