California Condor Eben McMillan 10 may 1964 after circling here briefly dropped into this Canyon out of sight. At 11:00 A.M. an adult Condor came from the North, in flat glide, so I feel sure it came from a distance, and after circling twice, dropped down and out of sight in the Canyon into which the other adult Condor had disappeared into only ten minutes before. Three Condors came out of this same Canyon at 11:13 A.M. Two adults and a spot-in-the-wing bird. One of the two adults had 4th primary missing from right wing and a gap in left wing also about where 6th Primary should be. The other adult had perfect plumage. These three Condors circled the area about foot of Kerr Grade for five minutes gaining considerable altitude before flying out towards the Southeast. After going Southeast a distance of about one-half mile, the spot-in-wing bird and the adult, with primaries missing, circled and returned while the other adult continued on Southward. Spot-in-wing and missing Primary adult returned and circled high for a few minutes then sailed out Northward where they circled several minutes above Rumbo Ranch before returning again to area about mouth of Kerr Grade, where they circled briefly before dropping in and alighting among six Turkey Buzzards that were feeding on the Sheep offal I had left on the Little Ridge this morning, about one-quarter mile North of the bottom of Kerr Grade. At first, both Condors acted suspicious of the Sheep Entrails—
