California Condor. Ebendmchillan. 26 February 1964 Where the Condor were feeding. None of the Condor seemed disturbed at the Noise caused by the passing of these planes. They did not fly nor stop feeding. A few moments before these planes came by, several Condor were circling at about the place where they later passed. These low flying, swift traveling, planes not only pose a problem to Condors but also to the personnel who are piloting these craft, for should they come in contact with a bird as large as a Condor it would no doubt damage the plane. At 2:20 Seven Condor were feeding on the deer carcass that they had now pretty well cleaned up except for the skin and had dragged down the hill northward about 250 feet. Some Condor seemed the rulers of the situation and took command, at the Carcass, whenever they chose. The ringed-neck bird showed some competitive activity and on one occasion was seen to faint towards an adult in a fighting attitude but was somewhat disregarded by the adult bird momentarily, and then driven away with one Peck of the others beaks. One adult seemed second from the bottom of the Peck order and would run at the ringed-neck bird each time it went to the Carcass remains to feed, other Condor always ran this adult away after it commenced to feed after it had run the immature one back. The ring on the immature birds Neck was not visible when the bird was on the ground unless it stretched its Neck out to feed on the remains of the deer. It was then even visible to the naked eye at the two-hundred yards distance I was from the birds. The red or reddish-pink of the lower Neck covered up about one-half the Neck proper. See below.
