Lophortyx Nov 16. The slope behind the spring was covered next, the dogs covering this large brush patch fairly well. We continued upslope to fence at 9:20. No quail on this slope. 9:25 - we started down brush of N-facing slope of ridge to N. 9:38 call from downslope - 9:45 eleven quail flew out of middle of brush by 2's and 3's. (see A.S.L.'s notes for sex ratio). These birds were not marked. We returned and crossed next draw 5 reaching road about 10:20. We "peeled off" and started down side draw which joins gulch a few yards above spring. Quail was flushed by the dogs well ahead of us - I counted 5 (genealy counted 10 in this flight). Then main body of cover flew down slope - I estimated 35 - these were followed by two couples, one of each marked by rock dangles. Keppel and Russell started down through brush heading for a point E of spring. At 10:29, 3 single flew up. 10:32 - one upslope, one downslope. 10:33 - 3 crossed side draw well behind dogs and hunters. I started down ridge W side draw at 10:38 - no more quail flew. We left area shortly after 11:00 am without seeing more quail.
