Gymnogyps californianus February 11, 1946 Hopper Canyon, Glif. with 7 others over to the top of the cave. I search- ed for other perched birds - found but one; this in sunshine near mouth of a cave between 3rd & 4th. east canyon from Hopper Creek S. of WT Canyon. In years past I had have seen condors (1 or 2) perched (Percy, Percy Pts.) in that vicinity. The cave was 200' above the stream; nodes were lightly whitewashed; a possible meeting site. The bird may have been a youngster of last year - very quiet & inactive and unchanged by 4:30 (since 4 or earlier). Even in protected spot it was difficult to write because of cold. The ledge at Big Cave at 4:35 looked about thus: 4:39 - 5 or + condors meaning about the cave tops, some with feet down & roosting birds to make at least 26. One gave 5 locking flaps, feet down in landing on ledge. 4:42 - 28 now, 2 in air. The wind still fair but somewhat unsettly, from WT. Some condors perched nearly touching & others in same pathole without alteration. 4:45, two ravens soaring near top of Big Cave. at least
