Order Anseriformes - Waterfowl Family Anatidae - Ducks, Geese, and Swans Subfamily Anatinae - True Ducks Tribe Anatini - Dabbling Ducks |
||||||||
Waterfowl vary in size - from teal to swans. They all have webbed feet and dense, waterproof plumage. Most nest on the ground and the nest is lined with down plucked by the female from her breast. Except for two small groups not found in North America, all belong to one (or two) families. Ducks, Geese, and Swans are waterfowl with their bill finely serrated or grooved on the edge. Their tongue is fleshy. Their front toes are webbed. Males have a functional penis. They are strong fliers and many migrate long distances. True Ducks are sexually dimorphic. The female incubates and cares for the young - the male usually deserts early. Ducks undergo a simultaneous molt of their flight feathers and are flightless until the flight feathers of the alternate plumage regrow. Thus, males wear their nuptial plumage on the winter grounds where pair formation occurs in most species. Dabbling Ducks all belong to the genus Anas. They feed on or near the surface or "upend," tilting their body vertically to feed on aquatic vegetation. |
