Gymnogyps californianus May 29, 1946 Nr. Mt. Poso, Calif. two near - at 2:55 I saw one cawder descending apparently over the Little Creek area N. & somewhat E. of Mt. Poso. I returned toward the road & car. At 3:05 I saw 7 cawders circling in a group over where the 2:55 bird was. at 3:10, still 7 there, speed 1/2+ mile horizontally & 400+' vertically. 3:17, 3 still there & 2 others 1/2+ mile to NE of them - apparently scattering and/or descending. The 5 minutes+ as a group I believe unusually long. 3:17, 3 were circling about 1 mile E. of where the 7 were - low, possibly descending, & 1 was about 1/2 mile W. of them - no others visible. Fair NW breeze continued. I returned to car & drove on to junction of McFarland-Woody & Famoso-Woody roads. There was a sheep camp with about 500 sheep there just S. of Little Creek. I continued on 1/2 mile to E. & saw then one adult circling & rising over the ridge just S. of Little Creek. This adult had 4+ nicks in trailing edge of wing & # 7 (+) left primary was about half grown. This bird rose to 300+' & glided over the road to NW. Then I saw another adult flap-circling & rising over the flat ground near the road about 1/2 mile ahead of me. This bird soared away from the road & skimmed the foothills when a car went up the road. The cawder nearly met its shadow in gliding close to the slope per
