of the dead cow. The young condor flew from its perch at 7:15 A.M., sailed down and lit on a dead limb of the oak within 70 feet of dead cow on which another adult condor was perched. At 7: one of the adult condors sailed down from its perch near that the ridge to the south and dropped in where the cow carcass I walked up canyon towards dead cow at 8:05 A.M. condor that sat in the oak near the cow flew out over me approached within 100 yards of where it sat. It moved over c alighted on a small pine to the south of me about 20 and upon getting settled on its perch commenced preening feathers. At 8:10 A.M. the adult condor that had dropped in where the carcass lay came out over me with full crop and red skin showing underneath. The swoosh of its wings was most impressive as it flew out over my position about 100 feet high. This bird flew, pumping all the way with its wings, westward about 400 yards and lit in a big closely branched pine tree in a crashing sound. I then moved on up canyon towards where the young condor sat on the dead oak limb. Turkey buzzards that were perched all over the place, were torn off with flapping sounds, some flying only to another tree, some circling overhead. The young condor let me pass 60 feet below the tree in which it sat. As I moved on past to a spot near the dead cow the young condor took off and flew to a pine to the south about 150 yards away and there it sat and proceeded to preen its feathers. The young condor flew much more easily than was the case with the adults. It appeared much lighter on the wing and the swoosh of its wings as it flew from the oak was much less in intensity than the case with either of the adults that flew before. The bird did seem to experience more trouble in landing.
