Stiff-tailed duck

（重定向自Oxyura）

Stiff-tailed ducks are part of the Oxyurinae subfamily of ducks. All have, as their name implies, long, stiff tail feathers, which are erected when the bird is at rest. All have relatively large, swollen bills. These are freshwater diving ducks. Their legs are set far back, making them awkward on land, so they rarely leave the water.
