Mayhew 1949 6. Pheasant Nov. 15 Conaway Ranch, 2 miles east of Woodland, Yolo Co., Cal.f. This afternoon Ed Little & I covered some rice stubble, irrigated pasture, & fallow ground in an effort & count more pheasants & increase the validity of the sex ratio I've been trying & obtain. By the time it was dark, we had counted 27 cocks and 34 hens. Added & previous counts, this makes 42 ? & 95 ?. Nov. 16 Starting at 2 P.M. today I walked over rice stubble & along ditch banks & count more birds. In all, I counted 41 ? and 41 ?. This brings the total & 219 birds -- 83 ? and 136 ?. This would be a ratio of 61:100, which is quite low before the season opens. Nov. 18 Dr. Leopold counted some birds this morning, & Lee Baldock counted some yesterday, so that the sex ratio count ended with 371 birds. Of these, 162 were ?, 209 were ?. This gives a final sex ratio of 78?:100 ?. As this was the opening day of pheasant season, a number of freshly killed birds were weighed & aged. In all, 79 birds were measured.
