Gymnogyps californianus
May 12, 1946 Nr. Famoso, Kern Co., Calif.
first, heading S. at 3000' above hilltops. It went
about 1½ miles S, then NW, teetering into the breeze,
feet down, wings flexed, for 3 or 4 minutes, then
rising. Then it turns a circle & glided to
W. for ½ mile with feet up, then put feet down
& spiraled down rapidly & disappeared between

location of descent was ½ mile N.E. of a triangulation
marker stop a hill - possibly Mt. Poos. One step
bank when descending was accompanied by wingtip

& rising with several turkey vultures over the canyon
just N. of the triangulation mark. 10:23-27 This group,
as usual, broke up in a minute or so. 10:23-27 I

down, feet hanging, & disappeared between the hills-
this bird, & many others, have gone down with
pumping oil wells a mile or so in the background.
10:33, I saw 7 + 9 turkey vultures circling & rising
about 2 miles to S.E. The groups scattered within 2½
minutes & the 4 condors headed SW- one went down

vultures circled in that vicinity (about 2 miles to
SSE). 10:53, I saw 7 circling about ½ mile E. of
the triangulation mark, & at 11:01, 1 condor and about
20 turkey vultures in that vicinity. I left my
