Because they breed in remote and little disturbed areas, Tundra Swans have so far escaped the fate of the closely related Trumpeter Swan of the West, which was reduced to near extinction by hunting and habitat destruction. In one study, Tundra Swans were marked with colored neck bands at Chesapeake Bay in Maryland, and their migration was followed to their Alaska breeding grounds. One bird, banded on the Atlantic Coast the previous winter, was sighted in the Central Valley of California in the following March. This Arctic breeder alternately visited the Atlantic and Pacific coasts of the huge North American continent, surely something of a record for birds.
