Green-winged Teal

Green-winged Teal. -- This species is distributed much like the American wigeon, but with an even more northerly center. The stratum including the Woodworth Study Area is in the lowest quartile of densities identified by Johnson and Grier (1988). Although the continental population increased during 1965-1989, the Woodworth Study Area experienced a marked and significant decline (Fig. 7).

The lack of association between green-winged teal and wetland numbers in the Woodworth Study Area is consistent with the finding of Johnson and Grier (1988). No weather variable was significantly correlated with numbers of this species.
