Page 136 —continued— Namejo California Condor Elben McMillan 27 June 1963 I had seen one-half mile down river from this spot at 11:50 A.M. on June 9, 1963. Carl Kroford thought this condor lacked the luster while under the wings of a full plumaged adult and he was of the opinion this bird was either just out of the post juvenile coloration or else it had molted several of the white under-wing feathers and the darker ones behind were showing through. This bird showed definite wide white bars on the back of the wings. But a thin, the slate color was somewhat dull on the back of this bird. After watching this condor gain altitude and drift downriver and having a Red-Tailed hawk move in behind it at one point, but not close enough to worry the condor — we lost sight of this bird. We then drove to the edge of the river-bed nearby, and hiked across the shallow water to investigate Food The sheep carcass that lay in the water and at which I had seen four or five Turkey buzzards feeding yesterday. In the sand near this sheep carcass we found several condor tracks Kroford thought had been made this morning, but from the experience had with the young condor tracks from which I made the plaster casts, I judged them to have been formed yesterday. We then drove to the river near 16 Spring and near the non-occupied trailer house there looked over the remains of a lamb that had been cleaned up a week, or so ago. We found no feathers that Dr. Kroford would class as being from a condor. We drove up on the bench overlooking the river here and partook of lunch provisions. Retracing our route we returned to the Navajo Ridge, proceeded along same northward and turned eastward down the steep roadway that comes out on the river one mile up the river towards Swall
