The Trumpeter Swan (Cygnus buccinator) is the largest native North American bird, if measured in terms of weight and length, and is (on average) the largest living waterfowl species on earth. Their breeding habitat is large shallow ponds and wide slow rivers in northwestern and central North America, with the largest numbers of breeding pairs found in Alaska. Natural populations of these swans migrate to and from the Pacific coast and portions of the United States.
