Gymnogyps californianus May 31, 1946 2 miles NNW of my 11:00 position at about 12:55. The bird on power tower was a golden eagle. I saw then at least 4- possibly 7- condors circling low about 1 1/2 miles N. of me (about 2 miles N. of Mc Farland-Woody road at power line & 1/2 mile W. of power line). I saw 2 condors too on a dry-grassy ridge there, & I saw 3 others alight- 5 on ridge within about 20' at 12:59. The breeze had shifted to W. about 11 a.m. & to NW about 12:30. Sky 9/10 alto-cumulus & alto-stratus. Breeze at times absent- perhaps the condors were decid ed. I sat to watch. The condors walked about occasionally. at 1:14 I saw one fly at another- the other flopped about 15', then both alighted. one again flew up & flopped off about 20'; then alighted & walked back to the group. 1:28, 3 of the condors took off about 30 seconds apart & flew behind the ridge. The last took off to W., flapping hard, turned after about 10 flops, & continued to E. behind the hill still flapping (20+ flops on takeoff & turn). Two condors remained on ground as before. The poison crew rode by about 1/2 mile N. of me. 1:35, one condor landed about 20' to E. of the perched two & apparently walked over to the other 2. The 3 made a compact group. Fair breeze from NW. 1:41, 3 still on ground, perhaps 20' between birds. 1:49, a fourth condor alighted.
