Whooper swan family
The whooper swan, also known as the common swan, is a large northern hemisphere swan. It is the Eurasian counterpart of the North American trumpeter swan.
Size is similar to the Mute Swan, but there are noticeable differences : a yellow and black beak, a more rigid neck bearing in activiy as well as at rest, and finally, their wings produce a musical sound when they fly.
Whooper swans pair for life, and their cygnets stay with them all winter; they are sometimes joined by offspring from previous years.
