Wood Ducks live in wooded swamps, ponds, and forest streams. Males have a green crest, a chestnut breast, and bold white lines on the face. Wood Ducks nest in tree holes, and their ducklings leap to the ground about a day after hatching.

A Mallard (Anas platyrhynchos) has a rounder head. A female Wood Duck has a large white patch around the eye that a female Mallard lacks.
