California Condor Eben McMillan 3 December 1963 minute they again settled down in nearly the same spot from which they formally rose and commenced feeding and chirping again. As they all rose into the air following my shrill whistle a fluttering was heard above the whirr of their wings that made he think some were crowding so close together in flight that their wings were hitting. I drove up Stone Corral Canyon to Stone Corral Flats where I saw another flock of linnets that numbered about 3000 birds. a pair of Golden Eagle that probably were the same birds I saw earlier circled above the Bog-hole spring in Stone Corral Flats. I watched these two Eagles circle overhead for some minutes and could see where their wings differ in shape from that of a Condor; for one thing they are more narrow in relation to the length of the wing than that of a Condor and the wing of an Eagle is wider out at the outer third of the wing than it is at the inner third of the wing. There seems to be a general narrowing of the wing as it nears the body, see below. Golden Eagle wing Condor wings
