2965 Gymnogyps californianus March 22, 1946 Hopper Canyon Cal.f. Had been visible from our position 3/4. After 2 1/2 minutes the bird folded wings & stood with back to us & sew. Adult slipped & regained footing with several flaps. It spread wings & sunned back for about 1 minute, the wings being outside the nest cave. At 5:17 the bird entered cave & slowly sat about as before after locating with head down (a look back or rolling egg). We continued on to camp at head of Hopper Canyon. March 23, 1946 Nr. Fillmore, Ventura Co., Cal.f. Cool clear calm night, some frost. With all cool drove from head of Hopper Canyon to Fillmore. At 7 a.m. saw at least 2 caddos, at Whitewash ledge (one about 15' above oak tops), none in Pole Canyon. Arrived Fillmore about 9 a.m. Drove to gate on Big Jespe road & hiked to Oil Well Paint -- departing by 1 p.m. 10:35 + arriving 12:30. Saw no action around old nest site opposite (toward Sulphur Pl.) the paint though whitewash was fresh appearing on several rock points & ledges in that area. Hiked through the brush & rocks up the slope toward the old nest. At 14:10 we saw an adult + immature (fuzzy head, perhaps a 1945 youngster) standing together on a rock about 100 yards from us. We dove into the brush & came up about 50 yards from them -- they remained.
