Gymnogyps californianus
April 23, 1946 Big Pine Lookout, Cal.
from this area. Saw no more by dorks.
April 24, 1946 Big Pine Lookout, Cal.
at 7 a.m. sky 1/10 cumulus, fair east wind, 60° F.
Air clear to W. so had good view of San Rafael Mtn.
& could probably see condors there as well as over
the upper big yellow pines in head of Falls Canyon.
Would spend the morning watching from the lookout.
At 7:20 I saw a large bird (possible condor) perched on limb of
a stub on N. side of San Rafael Mtn. - gone at 9 a.m. Saw
none from the lookout (with constant search) by 10:15.
Then hiked E. along cliff tops peering down to look for
condors or whitewash. At 10:25 I saw 2 adults cir-
cling about 1/2 mile SW of the lookout. Continued on
to about 1 mile E. of the lookout; saw 5 ± points on
the cliffs or rock points on slopes below to S.
which appeared to be condor perches. Many perch
point possibilities, a few conifers for roasts,
& many potholes & broken cliffs for possible
nesting sites on S. side of the Big Pine Mtn. ridge.
At 12:15 saw 2 adults part circling over a N.
slope about 1 mile E. of the lookout; they circled in
opposite directions & rose until 800' above top
of cliffs, then - ?. At 12:45 we were back at the
lookout - fair NE wind still, 68° F., sky 1/10
cumulus. Watched continually from the lookout
but saw none until 4:16. Then an adult was seen
