Ford 29/11 Gymnogyps californianus March 3, 1946 Hopper Canyon, Giff. at least 7 cardors then at Whitewash Ledge, at least 2 sunning brokes. About 9: 40 saw at least 5 on a flatish place below the ledge. An adult + youngster stood side by side at edge of a shadow, apparently pecking at the rock or plants. Also Those two wrestled with heads & necks a bit, then youngster slid sidewise 10' down the rock, wings flapping but did not take off. + to 1 to 3 of the other birds (of the 5) were also inum. Three birds (adult + 2 min.) were still on this flat at 10: 15 - the only cardors visible in the Big Cave area then. About 9: 30 I saw- 2 adults soar together down Cedar Canyon. One chased the other, crash dove, then rose flapping. At 9: 53 at least 4 were in air over Big Cave - "rising time" about 10 a.m. I judged. About 9: 45 I saw- 1 adult displaying at another for 3+ minutes atop Big Cave. Wings of displayer were held [illegible] & head down near feet. The displayer paced back & forth for a few feet about 1 to 5' from displayer, some- times apparently almost touching the latter. Displayer showed no reaction - just stood
