The American black duck is a medium-sized waterfowl native to North America. It is primarily found in wetlands, lakes, and rivers, where it feeds on aquatic plants, seeds, and invertebrates. The male and female have similar plumage, featuring dark brown feathers with lighter mottling, making them well-camouflaged in their natural habitat. This species is often confused with the mallard, but the American black duck has a darker appearance and a distinctive blue wing patch. They are known for their strong, direct flight and are typically seen in small groups or pairs. Conservation efforts are in place to protect their habitats and populations.
