Gymnogyps californianus May 4, 1946 Nri. Famoso, Cal'f. to E. of me, just beyond high the power line. 9:18 a large adult soared W. from power line vicinity, 100+ over the hills, & at 9:20 dropped into a hollow about 3/4 mile N. of me (closest condor I have seen so far today). I believe this bird landed. A maneuver often seen at low altitude is the dipping of one wing tip followed by a steep bank to that side. perhaps the dive is the result rather than the cause of the bank, the upcurved primaries snapping down when the turn commences. 1 or 2 buzzards flew out of the hollow where the close condor alighted. Back to Joe Keyes: he believes many road birds are shot along the roads so it's fearful of publicizing the condors because they too might attract shooters. Blue Mtn. Lookout can also be observed from this spot, so both Blue Mtn. & Oak Flat Lookouts should see condors. 9:30, the close adult flapped SW (down canyon) out of the hollow where it disappeared, then circled & rose, 2 buzzards apparently following it in air. Feeding (?) time here not over 10 min-- utes - apparently a squirrel does not keep a sow low occupied long. The close adult rose to 300+; the lizzard "escort" left, and (10:35) adult headed to NE in a long glide to join a group of 10 con- dors circling about 2 miles NE of me. I counted at least 14, possibly 16, at 9:39. Most slid.
