German: Marmelente.
French: Marmaronette marbrée.
Order: Anseriformes.
Family: Anatidae.

The Marbled Duck cannot be confused with any other duck. They lack the speculum, which makes this species easily distinguishable in flight.
Both sexes have a generally similar plumage. However, adult females have a less dark mask and markings than males. Adult males display ornamental feathers in the form of longer and darker ‘bows’ than females.
They exhibit a very similar plumage at all.
Primaries: 10 per wing.
Secundaries: 13-15 per wing.
Rectrices: 14.
