Mayhew 1950 May 20 Mallard 28. Conaway Ranch, 2 mi. east of Woodland, Yolo Co., Calif. or flew back toward a flooded field. However, I was unable to locate her nest. In that area the wheat is very thick + about 4 feet high, so that one would almost be on top of a nest before he could see it. At 11:45 A.M. I visited the pothole 1 mile north of the old ranch headquarters. I found a ♀ with 8 young about 2 weeks old. I looked around the edge of the pothole, hoping to find her nest + perhaps be able to tell how many eggs she had incubated, but I couldn't find the nest. May 30 At 4:30 P.M., when I reached the grain fields, I saw a total of 12 ♀ flying in out of the wheat + going to the flooded rice fields. Therefore, I didn't walk through the grain at this time. Every one that I saw was flying out of the wheat fields. II The ♀ on the pothole still has 8 youngsters. All of them seem to be healthy. May 31 At 10:45 A.M. I started walking through wheat fields + covered 6 more miles in wheat without finding a trace of a nest. This was still in the area where the majority of ducks were seen looking for nesting sites. This makes a total of 12 miles of wheat covered without finding a single nest + only one young brood.
