Anas

The genus Anas is part of the dabbling duck tribe, Anatini, within the family Anatidae. These ducks are found worldwide, primarily on inland waters, and are known for their habit of tipping up in shallow water to feed on aquatic plants, seeds, and insects. They typically have a flat, broad bill and unlobed hindtoe. Dabbling ducks float high on the water and are swift fliers. Males usually display bold plumage, except during their post-breeding molt when they resemble the drab females. Hens are generally smaller and more vocal than drakes. The wild mallard (Anas platyrhynchos) is considered the ancestor of all domestic ducks.12
