Classification

Class
Aves
Family
Anatidae

The masked duck (Nomonyx dominicus) is a tiny stiff-tailed duck ranging through the tropical Americas. Taxonomy The only member of the genus Nomonyx, it is intermediate between the rather primitive black-headed duck (Heteronetta) and the very apomorphic true stiff-tailed ducks. It is sometimes included with the latter in the genus Oxyura, but the masked ducks are now considered the descendants of a missing link in the Oxyurini evolution, having changed little for millions of years.
