Meller's Duck is a large duck with dark brown plumage. It lives only in Madagascar and is found at freshwater lakes, rivers, and swamps.
Meller's duck differs from other ducks in its dark uniform color without bright spots. It is important for Madagascar's nature because it eats plants and small animals in water bodies and serves as food for local predators.
