Gymnogyps californianus March 12, 1946 Hopper Canyon, Calif. adults circled overhead, some 60 + 'over, and at least one with feet down. At 1 p.m. a single adult circled overhead near sun (shadow attract- ed my attention). The pool atop Big Cove was dry. Nearest damp sand was 75' back from cliff edge - but no water there. Tracks were numerous up to 30' back from cliff edge, then few. I measured the length of stride x offset of several tracks with following results: 15 1/2 x 3 3/4, 14 1/2 x 2 3/4, 13 1/2 x 1, 12 x 2 1/4, 13 1/2 x 3 1/4, 15 1/2 x 3 (all inches). It is apparent that the canid is a rather straight walker, not a waddler. The toe of two foot often left a dragging mark up to next footprint - at least 12" and very straight. These toe dragging marks were found only in soft dry sand of course. There were patches of grass close to the many canid tracks but no evidence of grass being clipped. However there were numerous tufts of grass which had been pulled up by the roots, + a few small basily pub- escent plants which had also been pulled up. Pieces of down were common in the grass but no large feathers. There were man quite a few canid tracks around some small dry damp potholes in creek bed, 100' back from cliff edge, and 3 sets of tracks goin to - and I returning from - the next damp
