The elusive Marbled ducks (Marmaronetta angustirostris) of Dayet Aoua

The marbled duck, or marbled teal, is a medium-sized duck. It used to be included among the dabbling ducks, but is now classed as a diving duck. The scientific name, "Marmaronetta angustirostris", comes from the Greek "marmaros", marbled and "netta", a duck, and Latin "angustus", narrow or small and "rostris" billed.
