Gymnogyps californianus May 5, 1946 Nr. Famoso, Calif. Day. These seem to arrive & leave at about the same time as the condors but a few may hang around or even roost near the food after condors have departed. 9:12, I saw 2 condors circling about ½ mile S. of the bait, upper one with feet down, & a 3rd, ¼ ± mile further S. 6 condors & 3 buzzards in a loose group circling ½ ± mile S. of our bait at 9:15, at 9:17 I saw one adult drop down as if to land near the power line & road about ½ ± mile S. of bait. By 9:21 at least 3 condors had landed at that spot (about 100 yds. from power line towers it appeared). One turkey vulture passed 100± over the bait, then headed S. 9:24, I saw 5 condors & 6 ± turkey vultures flapping/flapping away to W. of the landing spot over the flat ground. One gave 2+ successive flaps, 9:27, I saw another rise flapping from that spot. It flapped seldom when at ± above height of power line towers, & rose circling over the spot where it took off. A bunch of condors & buzzards worked nearly over me, &? at least (condors) were circling 300±' over my bait at 9:30. The birds left within 2 or 3 minutes - per- haps they didn't see it.

There were no straight stretches in this circling - all curving flight. I watched
