Gymnogyps californianus
May 13, 1946
Mt. Poso, Kern Co., Cal. F.
near same spot. to 11:12, I saw 11 condors about
(oo at least 13 total)
1 1/2 miles to SE. 8 were circling in one bunch. They
glided N. in a loose group, strung out about 1 mile.
at least 7 continued N- in direction of the "triangle".
Two lasted behind. There were 3 vultures on ground
near where I saw them this morning (about 1 mile to
SE). One condor spiraled down, feet hanging, + landed
in midst of vultures at 11:17 with 3+ gentle
flaps. The vultures flew off as adult seconded but 3+
ed but it were on the ground again by 11:20. The second
condor circled over but did not land or put feet down.
By 11:23 the condor had walked about 60 yds. to
N., occasionally stopping. It pecked desultorily at the
ground area, then took off (11:23), flap-glided low
over the hills, then circled & rose until 500+ ' over its
takeoff spot at 11:29. Two vultures flew close to
it for 2 1/2 minutes during first part, + 2 were still
with it at 11:31 when the bird (an immature)
commenced a northward fly glide. This bird was a
"near-adult"; notch in center both secondaries, bilated;
notch in left side of tail. This bird swung nearly
over me (500+ ' up) where an swin. was circling,
then continued toward the burn alone. By 2 p.m. I saw
no more condors; fair wind, sometimes intermittent, temp-
erature 77° F., sky 4/10 cirrus & cirro-stratus, haze
dissolved (Bear Mtn. visible). From Mt. Poso, Adelaide
