Male Northern Pintail Duck (Anas acuta), Belchertown, Massachusetts. The Pintail is widely distributed and common being a strong flier and a long-distance migrant like the Mallard. Seeds of aquatic plants are its main food, but in winter small aquatic animals are also taken; when freshwater habitats freeze over, it resorts to tidal flats, where it feeds on snails and small crabs.
