Guide
Nesting on Arctic tundra and migrating long distances to favored wintering areas, this native swan was less affected by human settlement than was the Trumpeter Swan. Destruction of southern wetlands has reduced its former food sources in wintering areas, but it has adapted by shifting its habits to feeding on waste products in agricultural fields. The North American population is often called Whistling Swan.
