Gymnogyps californianus February 8, 1976 Hopper Canyon, Calif. to turn right, left edge of tail tilted down, then right wing tip dipped, then bird turns. The adult glided over Arundell Ridge & circled, the yo-imm. rose to 1000±', then headed toward Hopper Mtn. & gave 1 wing dip on the way. Breeze faint or absent; sky overcast with cirrus stratus. Smokes hanging in the valley; a poor soaring day so far, I believe, & these birds probably the first out. 11:43, saw two adults circling & rising over the ridge NW of #1 nest cave. They rose together to about 1000'; then glided together toward Whiteacre Peak. About 11:47 an imm- dure had appeared below the circling adults - it had an outer left secondary missing (at least 2 imm. seen today). It circled & rose to about 300'; then glided after the adult(s) (½ - mile behind). A fresh breeze now blowing up the canyon. Went to cliff top above #1 nest cave. Descended by rope to the cave. It smelled of condors but there was no ev- idence of it having been used since 1939. At 12:30 we left Oscar's & hiked E. to the road (quite lovely). Saw 2 condors circling over the rim W. of Oscar's. Later saw 1 over rim near North Cliffs - it came within ¼ mile, circling (adult). At about 1:20 saw 3 adults circling near where the road reaches top of the E. rim. A youngster circled near them.
