Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than Swans and Geese, which are members of the same family
The Anatidae are the biological family of water birds. The family has a cosmopolitan distribution, occurring on all the world’s continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and, in some cases, diving in at least shallow water.
