Gymnogyps californianus May 13, 1946 Mt. Poso, Kern Co., Calif. The birds approached the vicinity of 6+ low circling vultures, then worked N. again, rising (10:32). 10:39, they were scattered for 1/2+ mile at 500'+ in vicinity of my squirrel bait - but they continued on (at least 5 vanders today it appears). 10:41, I saw 7 vonders circling + rising over where I saw the 2 on ground - sometimes were with them. The group split up - 2 soared toward me while one worked to E. One of the approaches dipped behind a hill about 1 mile S. At 10:50 there were 4 nearly above me at 500'+; they rose quickly to 1,000+ & set out to NNW. One had a large patch out of left right side of tail tip, + one a #4+ left primary missing. Four I saw - 2 gave a wing dip as they commenced their long fly-glide. Three were about 50 yds. apart, +1 trailed 1/2+ mile. 10:53, the one which lattered to S. soared be- hind a hill about 1 mile to E SE as if to land - so at least 5 vonders present. At least 3 of the 4 were adults, one an immature. 11:00, I saw one vonder descend as if to alight between hills about 2 miles to NW, to W. of power line 1/2+ mile. There certainly seems to be little reason for where the birds feed - there is plenty of food close to Mt. Poso. 11:07, I saw two rise above the hills where 11:00 bird went down - these circled low, occasionally flep- ping, + at 11:10 descended between the hills again.
