Gymnogyps californianus June 14, 1946 Nr. Whiteacre Pk, Calif. side again, the bird remaining leaning forward in horizontal position for 10± seconds before raising up again. 8:12, adult stretched left wing down & back, the leading edge making a straight line. Then nibbled at nump area (about 4 nibbles/sec). Then slowly turned around by stepping around on the jiggling branch. Then crunched foot, pressed in scapular area, eye apparently closed, for 5± sec., then stood again & opened bill twice successively for 3± sec. period. This bird is not the puffy cheeked one. Crop aperture barely visible. 8:20, adult pressed almost continually, mainly at leading wing feathers, nibbling 4-6 times per second with bill. 8:28, adult gave a weird bow, the strangely flexed wings touching at elbows above the back. Then the bird stood, looking about quickly. Then 2 "yawns", as if clearing throat. Then another bow, the wings bent little flexed but folded again touching at elbows. Then wings folded again, & the bird sprang from perch down hill, commencing to flap at once. Flaps 2/sec. It flap glided out of my right into a canyon 3/8 mile toward Whiteacre Pk. & apparently alight on adult ed there. 8:37, I heard flaps & saw the bird land on the sunlighted ledge at S. side of mast (?) extreme about 30 sec. Later it jumped & flapped up to an 8± higher ledge about 6' from cliff top, & stood
