California Condor Eben McMillan 1 May 1964 Detail these defects. However the following were noted. 1 adult Condor: Fourth primary of left wing missing. 1 adult Condor: Gap in right wing close to body. Then of course the juvenile Spot-in-the-wing bird. The following diagram is to give some idea as to the location and shape of these spots. Immature spot-in-wing-Condor. This juvenile Condor could not have been much over one year old, if any. It showed poor capabilities in flight and at times when hit by side currents when circling it would be visibly disturbed. Also one adult Condor seemed to remain with it continually and once when this adult Condor had flown and alighted atop a nearby Oak tree another adult Condor came in and ran the immature bird away from the Calf Carcase, while this act was in progress the adult bird flew down from the tree and attacked the adult that had run the juvenile bird away from the Carcase. First adult Condor and juvenile then dragged Calf Carcase over hill out of sight. Second adult remained in sight, on ridge for some time. I then drove up and put out the Carcase of another dead Calf he had found yesterday. This about food
