K Dixon 1951 Lophortyx californica Nov. 16. CLEAR, COLD; STEADY WIND FROM THE EAST. I met Dick Glenelly at Inspiration Point on San Pablo Ridge at 7:00. We were joined by W.C. Russell and A.S. Leopold, each with his hunting dog, and we drove north 0.6 mi. to a gate to the water district property. We left the car there and walked down the ridge toward the E following the road to a point where it curves around the slope toward the spring. From here we went downslope to a small flat at base of draw to W of road. We split up, Glenelly taking the ridge and I, the grass, at the lower edge of the brush. The others followed their dogs through the brush. We started about 7:25 am and soon afterward a covey of quail flew upslope to W, all in the air at once it seemed. A.S. Leopold estimated 40 birds (almost a complete count); I saw no tags (neck markers) on any of the birds. We worked upslope and soon some of the quail flew out: 6, 9, 1, 1, 1 later 1, 1 then 1 downslope and another downslope at 7:32. 3 flew upslope (and 6 or 7 downslope at same time WCR) then 1 up, (downslopes at 7:55 1, another later and two singles at 8:00. We reached the cross-path about 8:10 - five minutes later a quail flew from brush nearly 8:25 - 9:38 - we worked up next brush-covered slope to W, ending at maple tree - no quail.
