Gymnogyps californianus June 12, 1946 Hopper Canyon, Gli.t. carcass, the other 10' downhill. 11:14, the vultures took off; one raven + a fourth imm. circled low over the bait. 11:15, two adults landed + chased the imm. from calf. 1 imm. took off. The perched adult as before with one imm. in same tree 20' below. 11:19, a third immature + a third adult landed near calf.

Minimum 9 adults + 4 imm. present. 11:30 - adult + imm. side by side in tree together still. 11:31, a dark imm. perched in dead Bo. about 200 yds.

The new adult sprang onto that
