Bean goose

The bean goose is a species complex of goose that breeds in northern Europe and Eurosiberia. It has at least two distinct taxa, one inhabiting taiga habitats (The Taiga bean goose, Anser fabalis) and one inhabiting tundra (The Tundra bean goose, Anser serrirostris). These are recognised as separate species by the American Ornithologists' Union and the IOC, but are considered a single species by other authorities. The related pink-footed goose (Anser brachyrhynchus) has also been included in the species complex. It is migratory and winters further south in Europe and Asia.
