Journal 21. Mayhew 1949 May 22 Conway Ranch, 2 miles east of Woodland, Yolo Co., Calif. Most of today was spent driving around the ranch to give Earl Hubbs a chance to shoot some cats for his research problem. The weather was warm, the sky cloudless, + no wind. A number of Mallards were seen, but not too many as pairs. In most cases, the birds seen were a number of drakes together. In addition to the birds seen previously on the ranch, the following were seen today: Red-shafted Flicker, House Finch, Kingbird, Snowy Egret + Screech Owl. June 15 Today I rode a grain harvester while it was harvesting barley in order to see how many pheasant + Mallard nests are destroyed by the harvest. We covered 31 acres today, + found 5 Mallard nests + pheasant nests. Of this number, 3 were destroyed by the harvester, the remainder were merely uncovered. A number of ♀ Mallards were seen flying low over the stubble, apparently searching for their nests. Occasionally they would drop into the stubble + walk around as though looking for something. Rarely was a ♂ Mallard seen. (30 Mallard eggs, 0 pheasant eggs) June 18 We covered 10 more acres of barley today with the harvester (a "side header"). 2 Mallard nests were found, with a total of 16 eggs. One of the nests was directly destroyed by the harvester.
