Gymnogyps californianus June 5, 1946 Whiteacre Pk, Calif. two adults at perched on the tip of a sandstone bluff on W. side of the ridge about ½ mile S. of Whiteacre Pk. This was same point when I saw mating display earlier this year. 10:05, one adult crouched flat but was up in 30± sec.. 10:08, one sunned, facing arm wings outspread & body erect. The other stood 5±' away, facing first, + sunned back, body tilted forward [illegible]. Both had ceased sunning by 10:11. 10:16, both took off to NW about 1 minute apart, circled together, feet down, then separated - I descended out of my sight as if to land about 500' below Whiteacre Pk. on the SW side while the other landed in cliff point 200± yds. up the slope from first perch (highest point on that slope). The perched adult mostly stood quietly & occasionally preened. 10:40, a raven perched about 10' on one side of perched adult, later 6±' on other & walked about 4' in front of condor in returning to first spot, the condor showed no interest. 10:49, I saw an adult was now also on the first (lower) perch point on tip of cliff [illegible]. Upper adult faced out from cliff [illegible]. No change by 11:00 - both quite inactive. At 11:25 the lower took off, circled, & rose near upper. The upper then took off & circled 100±' below opp other. they soared toward Rim as if to cross just S. of Whiteacre Pk., but lower locked altitude &
