The trumpeter swan (Cygnus buccinator), or simply the trumpeter, is a species of swan found in North America. The heaviest living bird native to North America, it is also the largest extant species of waterfowl, with a wingspan of 185 to 304.8 cm (6 ft 2 in to 10 ft 2 in). It is the American counterpart and a close relative of the whooper swan (Cygnus cygnus) of Eurasia and has even been considered the same species by some authorities. By 1933, fewer than 70 wild individuals were known to exist; extinction seemed imminent until aerial surveys discovered a Pacific population of several thousand trumpeter swans around Alaska's Copper River.
