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
