Gymnogyps californianus March 10, 1946 Hopper Canyon, Calif. the blind front. The 10' x 4' cave entrance was covered by piece of white ply composition board & cloth. The cloth flapped much & had 2 holes for Wale's cameras. At about 2 p.m. two ravens alighted 15 ±' from the car- cass, nibbled at dried blood, & carried off pieces of it. About 2:05 they started on the carcass & pulled hair from legs, side, belly, & head. Later we worked about 15 minutes at the exposed eye & reduced it to a socket with white tissue protruding. One or 2 ravens were on carcass almost con- stantly until 2:45 but apparently made no holes in the skin. Sky clear & fair breeze. By 4 p.m. no more action at the carcass. We left blind. The ravens had made no holes in side of the horse. The whole area now swoll and smelled strongly from 50 yards away. At 4:10 saw 2 cordon circling over Nath Point. At about 4:20 they headed toward Strundell Ridge. We drove back to Old Cabin and Wale left for Los Angeles. At 4:45 from Old Cabin I counted 10 cordon (4 in air) at Big Cave (1 atop Rabbit Tree, others on Whitewash Ledge). Sky 9/10 cirro stratus; haze to 4000 ft. level; fair W. wind. At 4:50 saw 12 cordon at Big Cave (8 on Whitewash
