Long-tailed Duck

Discussion

 The Long-tailed Duck was formerly known as the Oldsquaw. In midwinter Long-tailed Ducks begin their courtship displays. Several males gather around a single female and utter their mellow, barking, far-carrying call. Although courtship lasts until after the birds have returned to their nesting grounds, most birds are paired when they arrive in the North. In winter these diving ducks feed mainly on mollusks, shrimps, and crabs, but when nesting they switch to roots, buds, and seeds; the ducklings feed mainly on insect larvae. While most diving ducks paddle with their webbed feet, the Long-tailed Duck uses its partially folded wings to propel itself underwater. It is one of the deepest-diving ducks; birds have been caught in nets as much as 200 feet (60 meters) below the surface.
