| The male, shown here, has a chestnut body, a black head and a bright blue bill. It is very similar to the Lake Duck Oxyura vittata of South America and both species are considered by some authorities to be a superspecies. The female is different from its South American relative in being fairly plain with only faint markings on the head. |
