Anser serrirostris (Tundra bean goose)

The tundra bean goose (Anser serrirostris) is a goose that breeds in northern Siberia. This and the taiga bean goose are recognised as separate species by the American Ornithological Society and International Ornithologists’ Union, but are considered a single species by other authorities (collectively called bean goose), such as the British Ornithologists’ Union. It is migratory and winters further south in Asia.
