The Whooper Swan is a large species of waterfowl that is found across most of northern Asia and parts of Europe. They are migratory, flying up to several thousand miles between their breeding and wintering grounds.
The Whooper Swan is named for its loud "whooping" call. Like other species of swan, this all-white bird may develop a rusty tinge along its head and neck from dabble-feeding in iron-rich waters.
The Whooper Swan is similar in appearance to the Bewick's Swan (Tundra Swan). Whooper Swans have a larger patch of yellow along the base of the bill. The shape and size of this yellow patch is unique to each bird.
