Waterfowl Communities in the Northern Plains

Northern Shoveler

Northern Shoveler. -- The shoveler is widely distributed' and the stratum containing the Woodworth Study Area is in the highest density quartile. Neither continental nor Woodworth populations experienced a decline during the study period (Fig. 9). As for the blue-winged teal, counts of the northern shoveler were strongly related to numbers of wetlands in the Woodworth Study Area. This finding was consistent with that of Johnson and Grier (1988). Numbers were also higher in years when April temperatures were low.
