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.
