Gymnogyps californianus May 31, 1946 Nr. Mt. Poso, Calif. By the 3, 4 one perched one ran a few steps as if to get out of the way. 1:54, one soaring near the perched bunch- probably 1 of them as only 3 visible on ground. These are circled about 1/2 mile SW of the group then, 4 another soared near the bunch. 1:58, 4 visible on ground in a close group - these birds barely visible because of haze & heat waves at about 2 miles distance. 2:01, 1 corder + 3 vultures circling 200+ over the perched 3 (or 4). 2:03 the flying corder alighted in the bunch, I hiked toward the perched birds. at 2:35 I was just W. of the power line having come perhaps a mile, but the perched bird still appeared to be about 2 miles distant. There were at least 4 corders in the group - possibly 7 or 8 - and apparently 3+ Turkey vultures. I hiked 15 minutes more toward the group. At 3:05 I stopped to watch - there were 5 corders ooo o, one about 100' from the rest on a rounded grassy ridge about 1/4 mile N. of the Porterville- Bakersfield highway perhaps 2 1/2 miles N. of the McFarland road. There seemed to be a light colored object on the ground - a sheep carcass probably. I was still about 1/2 miles to SE of the birds. 3:10, only 4 visible, all at the carcass & occasionally tugging at it with bills. Two flew up flopping once & realighted. One took off at 3:17. Two took off 30 sec. later when first soared 50+ overhead, & the last at 3:15. One apparently realighted about 20'
