Swan

Description

The swans are some of the largest flying birds. They are large in size and have large feet and long necks. The males are usually bigger and heavier than females. The Mute Swan, Trumpeter Swan, and Whooper Swan are the largest swans. They can be over 1.5m (60 inches) long. They can weigh over 15kg (33 pounds). Their wingspans (this means the length of both wings) can be almost 3m (10 ft).

Most swans are white. These swan are found in the Northern Hemisphere. This means they are found in Europe, Asia and North America. However, the Black Swan is black with a red beak. It lives in Australia. The Black Necked Swan has white flight feathers, and black outer feathers. It lives in South America. They also have a small area of skin between the eyes and beak that has no feathers. This area can be different colors, such as yellow (for example, on a Bewick's Swan) or orange (for example, on a Mute Swan).

The Coscoroba Swan is different to the other swans. Some scientists think it is more like a duck or a goose. It is the smaller than the other swans. This swan lives in South America.
