There are various species of swans in existence.
Mute swans are all white in color, with black feet and bill, and some black coloring on the face.
They are one of the largest and heaviest of all flying birds. The wings are much longer than the bill and legs. The male has a wing span of more than 8.5 feet and can weigh up to 40 pounds. Swans are very powerful flyers. They ascend into the air gradually by extending their neck and running along the surface, whether on water or land.
