Gymnogyps californianus April 21, 1946 Sespe Canyon, Calif. to gain altitude has obviously been above S. slopes.

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
