Ford 3115 Gymnopus californicus May 31, 1946 N. Mt. Poso, Calif. 1 1/2 miles to N.W. of me, + rose higher, + drifted about a mile to E.. At 9:09 the group broke up & strung off to W., 1 or 2 at a time. In the groups, the 2 min. were 2nd. & 3rd. lowest birds. The micture trailed the bunch. The group scattered more than, and at 9:15 I saw 4 about 1 mile W. of the 9:09 position, scattered over about 1 square mile at 1000+ altitude. I watched one of these until 9:40. It glided to SW slowly for about 2 miles, circled & wandered in that vicinity at some high altitude, then glided fast to N. and at 9:32 was about at its 9:15 position. It continued on to N., then began wandering at lower altitude (300+)' apparently near the power line about 3 miles to NNW of me, & there I lost it at 9:40. By then sky was completely overcast with Cirro-stratus & a 20+ mph wind blew from S., & the mictures had disappeared from the near vicinity. At 10:27 I saw 2 condors circling about 3 miles to N. near the power line - and still at 10:45, wandering over the area at 300+ altitude. On a crossbar of one power line tower was perched an eagle or condor - probably the former - in that same vicinity. I left my stand at 11 a.m. & hiked northward, cross county. Spent some time hunting reptiles, so arrived about
