The Tundra Swan (Cygnus columbianus) is a migratory bird known for its striking white plumage and long neck. It breeds in the Arctic tundra and winters in shallow lakes and coastal wetlands. Tundra Swans are social, often seen in flocks and communicate with soft, musical calls.

Cygnus columbianus, commonly known as the Tundra Swan, is native to North America and parts of Eurasia. In North America, it is primarily found in Alaska, northern Canada, and migrates to the United States during the winter months. In Eurasia, it breeds in the Arctic regions of Russia and migrates to temperate regions in Europe and Asia during the winter.

Tundra Swans inhabit cold, arctic environments during their breeding season, including tundra lakes, ponds, and wetlands. These areas are characterized by low temperatures, permafrost, and a short growing season. During migration and wintering, they are found in a variety of wetland habitats, including estuaries, lakes, rivers, and coastal marshes, where the climate is milder.

Tundra Swans play a crucial role in their ecosystem by grazing on aquatic vegetation and contributing to the nutrient cycling in wetlands. They are adapted to foraging in shallow waters and are known to feed on a variety of plant materials, including roots, tubers, and stems of aquatic plants. Their migration patterns help link different ecosystems across continents.
