Gymnogyps californianus March 12, 1946 Hopper Canyon, Calt. sand about 130' from cliff edge. Another 100+ ft. back was the first water - it was clear & open but there were no radar tracks apparent in the damp sand. Cliff edge was obscured by brush from this water. Apparently, then, the raptors must drive elsewhere than atop Big Cave now. I hiked about 1/4 mile N. on cliffs & sat to watch. 2:10, one turkey vulture circled near top of Big Cave. There was one apparent radar atop Flat Pt. on Brundell Ridge. Light S. breeze, clear sky, 75°. At 3:10 about 2:30 as I ascended a rise an adult soared 100+ over me from opposite direction. It went straight for 1/4+ mile, then began to circle & whirled back over me as if out of curiosity. The trailing edge of wings & tail was ragged. The #7 primary of one wing was short 6+"; the #5 of other wing missing. In flight, feet are held together with toes lock [illegible]. Toes apparently very close togeth- er. At 3:20 I reached my car which was parked in sight of the horse carcass and about 1500 yds. SE of carcass. I saw one adult condor perched atop the rock point about 100 yds. S. of the car- cass. The bird held its wings up briefly \\, and seemed once to do a "wing bow", and took off about 3:25 and headed S. down the canyon. Perhaps I disturbed the bird in getting in the car.
