Gymnogyps californianus April 9, 1946 Hopper Canyon, Calif. Arundell Ridge. With telescope I saw 3 on this tree + 1 on Flat Ro., 100' away. One of the 3 took off- the branch shook violently & other bird on that branch raised & flapped wings to balance. 8:38I saw 14 total- 12 scattered from SE Canyon to Spring Meadow + 2 perched on Arundell Ridge. One circled 300' over old horse carcass. 8:41 one adult flap glided up the canyon to near North Creek, then flap circled using 4-12 flaps consec- utively, rising with the flaps, then gliding, the net result being an altitude gain. 8:45, I saw an adult atop a point 100' yds. S. of the horse carcass. This bird held wings up V as if about to take off. It then flopped down near the horse. I caused some disturbance then breaking brush & getting telescope ready for observation of that area. 8:53 saw an adult on the point S. of horse again & a few seconds later it was gone. It is probable that both yesterday & today my presence, even at a dist- ance, prevented condors from feeding on this carcass. saw 2 condors & 3 turkey vultures circling over White Cliffs, 3 circling over Old Colin, 3 over Big Meadow, 1 over Spring Canyon Meadow, 2 over Arundell Ridge. 9:00, saw 7 scatt- ered from our horse carcass to Old Colin. Two were very ragged having gaps in secondaries on both sides & at least 1 primary on both sides ('6 or more). 9:07, one circled above #1 nest, 2 over N. Rim, 2 over Big Meadow, 2 perched (one on Flat Ro., one on higher Ro. 100' away), 1 near Hopper
