Gymnogyps californicus
May 3, 1946 Nr. Famoso, Calif.
remained but flopped off 20±' as a second adult
landed beside the first (11:32), then walked back
toward adults as the latter each tugged at a squirrel
(11:41). The adults seemed to step on the squirrel with
one foot, then the other, then pull with tip of bill.
Each adult took 5± tugs, then stood quietly, then
took off one at a time (11:43). One took 3 hops be-
fure off, and 9 flaps before the first glide. Both
took off to 5. (downhill 5%, wind NW) leaving the
2 buzzards. 11:47, I saw 7 in air scattered about
1 mile & up to 400±' altitude. 11:50, 12 in view; some
having apparently risen from about 1 mile SE of
me behind a humps. There was a fair, steady,
NW breeze. 11:52, 13 condors + 3 buzzards whirled in
a column from 50' to 500' altitude about 1 mile
SE of me. 11:58, 6 of these tacked slowly NW near
me. 11:59, I saw one drop down as if to alight about
1 mile SE of me. 12:00, 1 adult soared overhead,
2 about 1 mile to E, + 3 about 1 mile to SE--soaring
very slowly, wings flaps. One bird had 1 or 2 rectrices
missing; another 2s battered wings & tail. One
might time condor speed here by timing
a condor shadow as it passes 2 successive
telephone posts. There was a high tension power
line (Edison) about 2 miles to E, the Paso oil wells
about 2 miles to S. 12:05, two flaps-glied up
