Gymnogyps californianus July 25, 1946 Hopper Canyon, Ventura Co. the third highest tree there. With a crouch & spring, this adult jumped to 35' higher perch in same tree - and 3t' higher yet by 12:20 (a stub branch, 12±"long). It is about 200 yds. from closest condor to carcass. 12:24, this last adult crunched flat on perch. 12:25, this adult took off quickly soared low over the bait, & continued across Hopper Canyon - I lost it at 12:30 against dark brush. The next highest adult left about 12:30- to ? - leaving 1 only perched; & this last left about 12:45. 1 p.m., I saw that 1 adult was perched on a top branch of dead Ps. about 150 yds. NW of carcass & facing it. Have seen no turkey vultures or ravens in the carcass vic- inity today, or anywhere near it. 1:12, an adult now also on Near Roost Tree. Yet another condor was atop a live oak about 100 yds. uphill from carcass. At 1:21, highest adult took off & skimmed this oak; the other took off & both swooped low over blind. Third adult also took off, & all 3 landed in a tall dead Ps. about 100 yds. NNE of bait, separated vertically about 10t' one (middle one) 15'. By 1:27, upper two had gone, leaving only vis- ible perched (adult), 1:36, this adult moved to 15' high branch & stood facing carcass. 1:49, I saw a third adult in Near Roost Tree. By 2 p.m., no change - all 3 adults stood facing away from bait. Heavy semi- blue clouds to NW; fair cool W. breeze; visibility good in Hopper Canyon. 2:30, the adults quite in -
