Tundra Swan

Cygnus columbianus

Length: 48 to 58 inches Wingspan: 6 to 7 feet Seasonality: Migrant
ID Keys: All white body, black bill, yellow spot in front of eye, large size

Tundra Swan - Cygnus columbianusWell-named, the Tundra Swan spends its summer months on tundra lands in or near the Arctic.  The North American race is often called the "Whistling Swan", while the Eurasian race is often called "Bewick's Swan".  This is the most widespread and common of the swans normally found in North America.

Habitat: Its summer breeding grounds are the lakes and ponds of the North American tundra.  During migration and the winter months, is most often found on shallow lakes, ponds, and estuaries, often in the vicinity of agricultural fields.

Diet: Primarily feeds on the seeds, roots, and stems of aquatic plants.  Will also eat large amounts of waste grain in harvested fields, as well as the occasional small invertebrate.

Behavior: Forages both on land and in the water.  In the water, forages by swimming on the surface and either grabbing food items from the surface, or by dipping its head and neck below the water for good.  As with some other waterfowl species, they have learned to take advantage of waste grain left behind in agricultural fields, and will rely heavily on such food sources during migration and in winter.

Breeding: Non-breeder in South Dakota

Song: Tundra Swan Song

Migration: Summers on the tundra in northern Canada and Alaska.  Winters in scattered locations in the west, along the Pacific and Atlantic coastlines, and elsewhere.

Similar Species: Trumpeter Swan, Mute Swan

Conservation Status: Numbers stable, possibly increasing.

South Dakota "Hotspot":  The northeastern part of the state, especially in and around Sand Lake, are prime locations to find Tundra Swans in migration.
