Gymnogyps californianus March 14, 1946 Hopper Canyon Ca ltf. also in air - all adults. 3:51, two adults circling near Big Cave, feet down, one about 100 yds. behind other. One alights on a sheltered point 200+ yds. W of Big Cave and 2/3 way to top. 3:56, the 2 off, one after the other. They soared together, follower the leader style until 4 p.m. when they alighted in on a point of the cliff S of Roast Tree. The trailing adult had feet down constantly. No flopping but an occasional wing "dip". The follower briefly chased a third adult, both birds flapping at times or diving together in front of Big Cave. At 4 p.m. three adults (besides the 2) circling over Big Cave, very low (shadows or xodes). At 4:05 I saw one circling over Parking Knoll. This bird rose to 800+ ft, then glided toward Big Cave area. 4:07 - three perched at in top of Roast Tree, on a whitewash ledge, & the one in air approaching (at least 5 total). 4:09 - two adults over Big Cave, one chasing the other, often banking steeply, both birds flap ping (6 total). 4:11 - one ship two were together on Whitewash Ledge; one (adult) took off & landed in pothole over Big Cave. 4:08,
