The Emperor Goose (Anser canagicus) is a medium-sized goose known for its striking plumage. It inhabits coastal areas and tundra in Alaska and Siberia. Notable for its blue-gray body, white head, and pink legs, it feeds primarily on grasses and aquatic plants.

Anser canagicus, commonly known as the Emperor Goose, is native to the coasts of Alaska in the United States and eastern Siberia in Russia. These regions include the Bering Sea and the North Pacific Ocean areas.

The Emperor Goose inhabits coastal environments, particularly tundra and wetland areas. They are often found in salt marshes, tidal flats, and along rocky coasts. The climate in these regions is typically cold, with long, harsh winters and short, cool summers.

The Emperor Goose is adapted to a coastal lifestyle, feeding primarily on aquatic plants, algae, and small invertebrates found in intertidal zones. During the breeding season, they nest on the tundra, often near water bodies, which provide both food and protection from predators. The species exhibits seasonal migration patterns, moving to more temperate areas during the winter months.
