CAPTION: Tundra Swan - Long neck and large, webbed feet
THIS MEDIUM-SIZED SWAN exists in three slightly different forms. The form that lives in North America is often called the whistling swan. Male and female swans pair for life. When they migrate southward after breeding, their young fly with them, and the family stays together until the following spring.
