Crested Duck (Lophonetta specularioides)

A distinctive, rather large duck that is common in wetlands, lakes, bogs, slow-moving rivers, and along seacoasts. Sexes look alike: grayish brown overall with bold pale dappling on sides of body, a darker face, and a short bushy crest (often hard to see); bill and legs dark gray.
