alifornia condor Eben McMillan 9 August 1963 John Rofer had seen two condor last week. I lunched here and watched buzzards from 1:45 to 3:15 P.m. At 3:15 P.m. an adult condor was seen circling to the North, among several turkey buzzards, above a point and quite high above the buzzards as well as the point. This condor was also having problems remaining stable in flight. Of course the steep points up which the west wind was racing from the warm canyons below would account for this. The buzzards were like swallows bashing about on this wind. The condor remained somewhat stationary above this point, that was across a deep canyon from me and about one mile to the North, for several minutes being able to remain facing the West, all the time, and still maintain its elevation, or probably increasing its elevation, as it floated above the upcurrents of air. At 3:25 this condor commenced to drift Southward, dropped into a flex glide and quartering into the wind moved swiftly away and was lost from sight at about 3:27 P.m., the air now becoming very hazy and dull, limiting good visibility to a clear day minimum. No buzzard or condor came to the carcass of the cow that lay in the canyon north of the Rofer place. I drove south to the place where Kern River emerges from mountains. The steep mountains that rise abruptly from the plains, at this point, should be a natural funnel for condors as they would have to pass over open lowlands if they stay too far west and to pass east of
