California Condor Eben McMillan 28 June 1963 rapid this bird could beat the huge wings without Creating any evident energy or thrust upwards. After the Condor had beat its wings it remained stationary for several minutes while the Buzzards that had dashed away a safe distance, while the wing beating [illegible], how returned to the carcass to feed. The Condor now disregarded the Buzzards feeding and gave signs of being regal. After a three minute wait, after the wing beating, the Condor spread its wings a bit, hopped down the hill two or three times and took to the air easily, drifting directly down the canyon and out across the river valley to a point well on the east side of the river valley before it commenced to circle and gain altitude. As it circled and rose upward I took several pictures to show the glint of shine that reflects from the upper wing and body feathers of adult Condor when they bank into a turn when circling for elevation. After gaining some altitude this Condor then drifted over towards me giving good opportunity to see that this was yet another bird that I had, as yet, not seen. Only two outside Primaries of the left wing were full length, giving a queer appearance to this wing tip. All other wing feathers seemed to be in good shape and the white under the wings of this bird was very bright white. This Condor circled above me for several minutes, gaining moderate elevation after which it went into the flex-glide and moved along towards the southeast. It lost altitude fast and when last seen was below the top of the hills to the South of Carnaza Canyon and moving along southward to the east of the San Juan River Valley. When last seen this bird was heading into a canyon area. The time was 1:15 P.M. I drove to area on San Juan river below La Piazza bridge -
