california Condor Eben mcmillan 27 June 1963 Rock from Cedar spring. Rolf koford spent some 10 or more minutes shooting his 22 caliber rifle at a jackrabbit that ran out in front of us just before we reached the river valley floor. From where Rolf was doing this shooting we could look down and see several Buzzards and a Raven feeding on the Cottontail bodies we had left near the waterhole this morning and near where the dead sheep lay in the river-bed. Rolf's shooting did not disturb any of these Buzzards nor the Raven that fed with them. Driving to this waterhole, we did not frighten the Buzzards into the air until coming within 200 feet of them and three of these Buzzards that were feeding on the sheep carcass in the river-bed, and hidden from our view by a low bank, did not see us and flush into the air until we walked within 40 feet of them. All remains of the four Cottontails we had left this morning at this site had been cleaned of all edible meat by the scavengers. The fur and bones only remaining. We all searched this area for feathers, or tracks, of Condor, but found none. Several Buzzards continued to circle this area while we were there. Leaving this waterhole, we drove down the river valley, at 2:20 Pm., As we reached the canyon up which the road runs, To reach the ridge, up which the road proceeds to the top of the Navajo ridge, we saw an adult Condor flying over the tops of the low Oaks that are scattered about the hillsides here, and pumping its wings in order to get elevation. From its flight pattern we were quite sure this Condor had just left dead sheep carcass that is on the hillside across the canyon from this road we were on, but only in sight further up the ridge then where we were now parked. As this Condor gained elevation and commenced circling North of us and above the river valley, we could identify it from missing feathers as the same Condor we had observed on the San Juan River at 12:30 Pm., one mile north of La Panza bridge on highway 178. This adult Condor gained altitude very fast and in Ten minutes was very high but to the Northeast of us from where it went into
