Richardson 1937 Mallard Duck (Anas platyrhynchos) May 27, 1937 opening of 20 mi. Cr. into Warner Valley, Oregon Two nests, from which 7s were flocked, were found and probably two others could have been found with more search. Both nests were located under sagebrush in the area of high chaparral. Curiously, the first nest found was about 100 yards from the nearest small tributary of 20 mi. Cr., although within 75' of several small pools not more than 2' across or 10' long. The young ducks must either be led to the distant running or more extensive water, or must grow up on the very small pools already mentioned. The former seems more likely for the small pools are drying up. The nesting of Mallards in this habitat cannot be considered atypical for they are common here. May 29 as above - Another nest found, with only 5 eggs compared to '1' in one of May 27. Probably this time of year is about the start of duck breeding.
