california condor Ebem McMillan 1 July 1963 The Buzzards fed on the Ground Squirrels first then on the Jackrabbits and never on the Sheep while I was there. at 3:20 p.m. an adult Condor sailed in from the Southeast circled above where the Buzzards fed. Two or three times and then alighted on one of the top branches of a moderately sized Oak tree that was up the draw from the carcasses about 150 yards and about 100 feet higher on the hillside. This Condor landed on a rather small branch and being headed West when alighting had some difficulty in turning around to face downhill where the Buzzards were feeding - a Buzzard came and alighted in the same time. Soon after the Condor alighted, 16 Plus Buzzards were now competing over the Jackrabbit Carcasses, and the squirrels already having been consumed, much wing flapping going on. The Condor held its wings to balance as it shifted its position on the branch from time to time. It also did some preening of its front breast feathers. at 3:35 p.m. the Condor flew from the Tree, circled above the feeding Buzzards twice then set down on top of the hill, directly above where the Carcasses were left, and about 150 feet from these Carcasses - It stood on this hilltop for several minutes looking about, then crouched low, gave three hops, opened its wings and circling dropped down and alighted on the hillside about 30 feet above where the Buzzards were feeding on the Carcasses. after alighting here and several times thereafter when among the Buzzards this Condor would look down at the ground and hop about as though afraid that a snake or a trap of some sort was concealed there. After alighting near the Buzzards this Condor took several minutes looking about before it moved down among the Buzzards. When the Condor did walk down among the Buzzards, they all gave it clearance and to any Buzzard that hesitated to get out of its way a menacing attitude with head down, wings partially extended -
