Bean Goose Anser fabalis/serrirostris
Bean Goose is treated as two species in the IOC taxonomy: Taiga Bean Goose, Anser fabalis, is a rare visitor, while Tundra Bean Goose, Anser serrirostris, is scarce but regular. It is sometimes impossible to assign an individual to one or other of the species but as the two will be split after adoption of IOC in 2018, observers are asked to attempt the identifications.
