A List of British Birds (BOU, 1915) states that the Bean Goose Anser fabalis is a winter visitor, more common on the west coast of Britain than on the east. It was also common in central Ireland many years ago (Yarrell, 1884-1885) but is no longer a common visitor to Britain with just two flocks of the southern Swedish Taiga Bean Goose A. f. fabalis population wintering in the Yare Valley, Norfolk and Central Scotland on a regular basis. On other occasions we get winter influxes of the Tundra Bean Goose A. f. rossicus which breed on the western tundras of Russia and usually winter in The Netherlands, Germany, France and central Europe. When they arrive in Britain, these birds are prone to wander around the country during winter. They generally start their migration back to the breeding grounds in February.

Bean Goose taxonomy has been subject to fairly regular revision in the last two decades and I have added some recent research findings under the closely related Pink-footed Goose heading. The British Ornithologist's Union (BOU) currently recognises two species, Bean and Pink-footed Goose. However, the International Ornithological Congress (IOC) recognises 3 species, Taiga Bean Goose Anser fabalis, Tundra Bean Goose Anser serrirostris and Pink-footed Goose Anser brachyrhynchus, and these were adopted by the BOU on 1st January 2018.

A flock of ten birds noted feeding together in a field on the north side of the lake by the duck count team in February 1990 were identified as Taiga Bean Geese Anser fabalis and, at present, this is the only record of this species to have occurred. The Report on National Wildfowl Counts states that, unusually, very small groups of Bean Geese appeared at numerous sites in Britain during the 1989/90 winter (ABR, 1990).
