Gymnogyps californianus March 12, 1946 Hopper Canyon, Calit. at about 3:25 two condors circled over the W. Rim about a mile S W of carcass. At 3:35 two (same?) circled together about a mile S. of and 500t's above the carcass. 3:45 - the 2 now 5. 17 turkey vul- tures were over Rim west of carcass, apparently working southward. One condor circled below them - about between rim and carcass. 3:50, the group of 5 dispersed, but 3 scattered 500t' over or 1/4 mile S. of the carcass. 3:55, 2 of the 3 headed toward Condor Cliff area. 3:59, the third too headed SE at higher altitude. None came closer to carcass than about 300 ft. above it. 4:05, 3 condors were circling the divide at and rising together overhead of Hopper Canyon. One headed S. when altitude about 800 ft. 4 other two continued circling. About 8 turkey vultures milled in a separate group about a mile from the condors. An occasional vulture passed near the condors but there seemed no tendency to join them. 4:10 - no con- dors in sight. I walked a short way down tractor trail. Saw 2 in Roost Tree at 4:30 (same 4:45-1 on tip top, one flattened on top branch) and at least 2 on Arundell Ridge (1 on saddle Pt., 1 atop green tree near Flat Pt.). Returned to camp. Visited the horse carcass. Found no evidence of con- dor turkey vultures, or coyotes having fed upon it.
