WATERFOWL of The World

The order Anseriformes contains about 150 living species of birds All species in the order are web-footed for efficient swimming and have a large wide bill with a specialized tongue that allows water to be sucked in the front of the bill. An array of plates traps food particles as the water is expelled out the sides of the bill. Not all species feed this way, some graze on plants and some also catch fish.

Anseriformes has 3 familes, but almost all of the species belong to Anatidae.
Family Anatidae: dabbling ducks, teals, diving ducks, sea duck, shelducks, geese.

Order Anseriformes    Family Anatidae 

Teals belong to genus Anas as is also true for dabbling ducks. Teals have been given their own web page as an arbitrary way to split the presentation of this large genus. Teals do not totally submerge when feeding and are often seen with just their rears showing as the search for food. Because of their feeding method, teals have evolved to be more buoyant than diving ducks.
