The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.
NatureMapping observations reported by townships throughout the year.
The Tundra Swan winters in flocks on shallow ponds and lakes along the coasts of Washington and Oregon as well as in the entire state of California. This bird has extensive breeding grounds along the north coast of Alaska, the Yukon, the Northwest Territories and Nunavut (renamed part of NW Territories).Text edited by Gussie Litwer
