Description: The yellow coloration on the beak takes up over a half, and extends over the black top in a clear close angle, which renders the whooper apart from the Bewick’s Swan. When afloat, whooper swans pull their wings tightly to their backs, usually keeping their necks up and straight. Their length is 145-160 cm.
Habitat:Islands in lakes, swamps overgrown with sedge, reeds and shrub, or expansive mossy bogs and marshes. The species is rare and protected.
