California Condor Ebony McMillan 16 may 1964 Sixth or seventh Primary of the left wing that appeared to be filling in. The spot-in-the-wing Condor had a secondary feather missing from the right-wing-about two-thirds of the way out from the body. Both these Condor circled to the east and then south of where I was, gaining considerable altitude before flying out to the south, and out of my sight, at 11:20 A.m., heading in a south by southeasterly direction. I feel quite certain that these two Condor were the same adult and immature birds as I saw on May 10-1964 feeding on the sheep offal that I had placed out north of the foot of Kerr Grade. The only changes that seemed to have occurred since that time, in these birds was a loss of a secondary feather in the right wing of the immature bird and a gradual filling in of the gap in sixth or seventh primary feathers of the left wing of the adult bird. Arriving back at my pickup at 11:32 A.m., I glanced up to see both spot-in-wing and adult condor with 5th primary missing from right wing and gap in left wing in area of 7th or 8th primary feathers coming from southeast moderately high. Both birds circled over the mouth of this canyon where I had parked my pickup. The adult seemed to stay rather high while the spot-in- wing bird would circle much lower in elevation. It seemed also that the immature bird more or less wandered about aimlessly while the adult followed wherever it went, the adult usually remaining at a higher elevation as it followed the young and circled. At 11:37 A.m., these two Condor moved out eastward—
