Gymnogyps californianus June 6, 1946 Nr. Whiteacre Pk, Calif. restive nest site (within 1/2 mile say) such as Big Cave or Trumbell Ridge or Pine Canyon. 9:20, the perched adult gave a deep slow wind "how" to NE, then slowly turned about & faced SW as when first seen today. The broken shell below near Big Cove may have been from same pair as Works nest & the one near Cadora Falls. The nest at Oscar's house North Point may then same pair. And several locations at Beartrap Canyon (Trumbell) and Pine & Coldwater Canyons (Beytans). So perhaps nesting for life is indicated though same hole may not be used always. Disturbance at one site might easily drive the pair to another, the zone might use the same. 9:39, the remaining adult took off & soon straight WNW over the Little Scape area, & I lost it — first may also have followed their route. Breeze ceased & intermittent the air felt fresh. I moved S. then at at 10:10 was on the high bluff point where I saw cadora perch yesterday. At 10:22, "Puffy Cheeks" soared past about 200 yds. to W. of me, feet down, then to WSW, feet up, for about a mile, then back, feet up down, & swooped to a landing out of my sight on or near the NW facing cliff 150' below me (below & NE of lower cliff perch pt. point, 200' yds. E. of roost tree of this morning). There is a whitewashed ledge & pothole near center of that cliff, possibly so probably that is where the cadora landed. At 10:38 the adult was in air. It soared about 1/2 mile N;
