The rare Masked Duck of South Florida and South Texas is most similar to the Ruddy Duck but the adult male Masked Duck in alternate plumage has a dark face. Female, immature, and eclipse-plumaged males have one more dark line on the face than the Ruddy Duck. Most other diving ducks do not have the long, stiff tail of the Masked Duck. Hooded Mergansers can sometimes hold their tails erect like Masked Ducks, but have crests and long thin bills.
