This duck eats acorns, insects, corn, and seeds of buttonbush, hickories, and wild millet. The call of the female is a loud “wheee-e-e-k, whee-e-e-e-k,” and the male’s call is “twee,twee.” It may be seen sitting on a tree limb. When flying, it bobs its head up and down. While swimming, it floats high on the surface of the water. The wood duck will nest in a tree cavity, barn, chimney, or a constructed wood duck box.
