There are 3 subspecies of Taiga Bean Goose Anser fabalis recognised:
The Tundra Bean Goose A. serrirostris has 2 subspecies:
Some modern publications list all five subspecies above as Anser fabalis, as work on these taxa is still ongoing. We are following the names and divisions currently published in the IOC World Bird List.
Our native subspecies, the Western Bean Goose A. f. fabialis is common in collections and is easy to maintain here. The remaining four are not considered to be so easy.
They should be fed grain and pellets as well as being provided with good grazing.
The Taiga Bean Goose is a bird of the high Arctic or taiga, where it favours lakes, pools, bogs, swamps, wet meadows and sluggish rivers. Bean Geese also move to marshes and agricultural land in winter. The Western Bean Goose breeds in the taiga from western Siberia to Scandinavia, it winters in Western Europe with small numbers regularly occurring at sites in Scotland and eastern England.
Superficially, they look similar to their closest relative, the Pink-footed Goose Anser brachyrhynchus, but have warmer, more brown plumage. The key differentiating feature is leg colour. The yellow-orange patch on the bill usually covers more than half in Taiga Bean Geese.
An average of 4–6 white to pale straw-coloured eggs are laid in a scrape or shallow nest of vegetation. The nest is lined with down. Incubation is 25 to 29 days. It is worth noting that the bean geese can interbreed with several other geese including the Greater White-fronted Goose Anser albifrons, Greylag Goose Anser anser, Pink-footed Goose Anser brachyrhynchus, Snow Goose Anser caerulescens, Barnacle Goose Branta leucopis and of course, the other species of bean goose.
