A small duck with striking black-white and chestnut plumage in males and a cinnamon crest in females. It dives for food in North American ponds and rivers.
Males raise a large crest and show bold black-and-white markings with chestnut flanks. Females have brown bodies and a warm cinnamon crest.
It catches fish, crayfish, and other prey underwater with a slender serrated bill, and nests in tree cavities. Ducklings leave the cavity within a day of hatching.
