Length: 15 in. (51 cm)
One of the smallest ducks in North America, this teal is found mainly in shallow ponds, marshes, flooded fields and muddy banks. In the winter it forms small flocks and feeds largely on seeds floating on the water's surface or on wet beaches. During the summer it adds aquatic insects and other invertebrates as well as plant shoots to its diet. The nest is hidden in dense grass usually near the water. It is made of grass and leaves and lined with feather down. The four-digit banding code is AGWT.
