Comments: One of the most common and well-known waterfowl species in the world, the Mallard is found almost anywhere in the U.S. near shallow freshwater. Here in the Mid-Atlantic, female and juvenile Mallards can be difficult to distinguish from American Black Ducks at a distance. The American Black Duck (Anas rubripes) has much darker plumage overall (with lighter head), and its purplish speculum (patch of feathers on the wing) lacks the Mallard's white border. The Mottled Duck (Anas fulvigula) of the Southeast is also closely related.
