Whistling Swan
Appearance: - The Whistling Swan is similar to the larger Trumpeter Swan and has a white plumage, a black beak with a salmon-pink streak along the mouthline and variable amounts of yellow at the base of the beak which may be lacking, dark-brown eyes, and the legs and feet are black. The female (Pen) is similar to the male (Cob) but is usually slightly smaller.
Notes: - The Whistling Swan and the Bewick's Swan are known as Tundra Swans. They are called Whistling Swans not because of their call but because of a high-pitched sound made by their wings whilst in filght.
