Gymnogyps californianus May 31, 1946 Nr. Mt. Pso, Calif. from the carcass, then took off again at 3:17 & I saw 4 in air. All took off to SE downhill & downwind it seemed - with many flaps. 3:20- 4 in air, 2 at about 100' & 2 at about 400'; two turkey vultures slighed at carcass. 3:21, one vulture alighted between the two vultures at the carcass (they were 20±' apart). The vultures flapped off 10± seconds later. 3:22, a second vulture alighted. One stood at or on the carcass, apparently feeding, & the other stood 15±' away. The latter walked around the carcass & swung from side opposite to first vulture. Both flew side by side then. 3:30, one feeding, head down for about 5 seconds, then up for about 7-7 sec- onds, the other bird standing calmly alongside. Sky 6/10 cerous, fair NW breeze, visibility best of the day. 3:40, both apparently feeding side by side. 3:45, both at carcass still, apparently feeding, sometimes on opposite sides of carcass & sometimes on same side. I walked again, keeping the vultures in sight. At 4:07 they took off, one about 15 sec. after the other, when I was about 1 mile away. The birds took off to SE, downwind & downhill, then turned E. & flapped with few pauses for about ½ mile, then circled and began to rise. At 4:14, they were at about 1,000' altitude, about 1 ½ miles ESE of the carcass. They continued to circle & rise. Both were adults.
