Feeding

The Pintail feeds by dabbling and upending in shallow water for plant food mainly in the evening or at night, and therefore spends much of the day resting.[9] Its long neck enables it to take food items from the bottom of water bodies up to 30 centimetres (1 ft) deep, which are beyond the reach of other dabbling ducks like the Mallard.[11]

The winter diet is mainly plant material including seeds and rhizomes of aquatic plants, but the Pintail sometimes feeds on roots, grain and other seeds in fields, though less frequently than other Anas ducks.[11] During the nesting season, this bird eats mainly invertebrate animals, including aquatic insects, molluscs and crustaceans.[10]
