The Trumpeter Swan (Cygnus buccinator) is the largest species of waterfowl with a wingspan that can exceed 10 feet.  It is also the heaviest living bird native to North America.  In the early part of the 20th century, with a population of less than 70, the trumpeter swan faced extinction.  Aerial surveys eventually discovered a population of several thousand trumpeters around Alaska's Copper River.  Some of these were carefully reintroduced to other areas and now the population exceeds 46,000 birds.  The adult trumpeter swan has an all-white plumage, while the cygnets are light gray with pink legs.  After about a year in age the cygnets gain their adult plumage.  The breeding habitat of trumpeter swans is large shallow ponds, undisturbed lakes, pristine wetlands and wide slow rivers, and marshes.  The largest numbers of breeding pairs can be found in Alaska but they also breed in northwestern and central North America.  In the winter, natural populations of swans migrate in V-shaped flocks to southern Canada, and the Pacific Northwest.  This trumpeter swan was photographed while wintering on the Skagit Flats near La Conner, Washington State, USA.
