Introduction
The Whooper Swan (Cygnus Cygnus) is a bird belonging to the Anatidae family.
Description
He measures between 140 and 165 cm. The heaviest bird can weigh 14 kilos. The plumage is entirely white, its bill yellow and black. The color of the beak distinguishes it from other swan species; the yellow is very extensive and only the tip of the beak is black unlike the tundra swan whose beak is mainly black. The distinction between the whooper swan and the Bewick’s swan is more delicate, the yellow on the beak of the Bewick’s swan being generally restricted to the nasal region. Birds feeding in ferruginous waters often have reddish tinged plumage.
