Gymnogyps californianus
April 21, 1946 Sespe Canyon, Calif.
to gain altitude has obviously been above S. slopes.
The falls at Oil Well St. was running well - it
should be a good drinking place for condors. On
the bluffs near top of Sulphur Pk., 2 or 3 well white
washed ledges are visible - maybe not condor perches.
10:30, two condors spiraled down, wings flexed,
feet down, & landed atop a bluff 50+ yds. S.
of lip of the falls. At least one was adult. They
alighted 10+ sec. apart, adult first, the adult
remaining in my view but other hidden beyond
it. The adult's perch & other rocks near falls
tops were apparently not whitewashed at all, so
probably not a frequent perch. 10:38- adult gone;
could not relocate. Perhaps it dropped down to
water, or perhaps soared toward Bear Heaven.
10:42, I saw 3 circling above Sulphur Pk. - they
rose to 1000' above it, then I lost them. From
11:00 to 11:15 I watched one circling about ½ mile S.
of mouth of West Fork - this bird made little change
in altitude or location during this time; at 11:15
it glided W. At 11:15 I saw me circling near the
bluffs just W. of Sulphur Pk., its shadow crossing
the cliffs several times. At 11:20 this one headed
SE, from Fair S. wind continued. 11:42, I saw two
on the skyline atop a boulder at top of falls
to SW of Oil Derrick. Apparently this was the
