Black Duck
Scientific Name: Anas rubripes
A dark body, light head, and yellow bill distinguish the black duck from the mallard hen, with her more uniform color and orange bill. Both species dabble and tip from the water’s surface for their food. Plant matter forms the bulk of their diet, but they also eat small animals, especially the saltmarsh snail. Size: 19 to 22 in. (48 to 56 cm)
