WATERFOWL of The World

The order Anseriformes contains about 150 living species of birds in three families: the Anhimidae (the screamers), Anseranatidae (the Magpie Goose), and the Anatidae, which includes over 140 species of waterfowl, among them the ducks, geese, and swans. 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.

Swans

Order Anseriformes    Family Anatidae


The true swans belong to genus Cygnus. They are the largest waterfowl. Geese are their closest relatives. The sexes are alike in appearance, but the males are larger. Quite unsual for birds, swans have "teeth" - jagged parts of their bill that are used for catching and eating fish. In spite of this they are mainly plant eaters. The Coscoroba Swan is not a true swan.

Swan, Tundra
Tunda Swans are sometimes split into two separate species: Bewick's Swans of Europe, Asia and Whistling Swans of North America. Since their heads coloration is decidedly different, the two species approach is followed here.

Swan, Bewick's Cygnus columbianus bewickii also Cygnus bewickii  Found: Europe, Asia
The Bewick's Swan has white plumage and a black bill with yellow at the base. Also considered to be a subspecies of the Tundra Swan.
Similar to: Whooper Swan. The yellow on the bill of the Bewick's Swan's bill stops well before the nostrils. On the Whooper swan it continues past the nostrils.
