Description
The length ranges from 68 to 90 cm (27–35 in), wingspan from 140 to 174 cm (55–69 in) and weight from 1.7–4 kg (3.7–8.8 lb). In the nominate subspecies, males average 3.2 kg (7.1 lb) and females average 2.84 kg (6.3 lb). The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange. The upper wing-coverts are dark brown, as in the white-fronted goose (Anser albifrons) and the lesser white-fronted goose (A. erythropus), but differing from these in having narrow white fringes to the feathers. The voice is a loud honking, higher pitched in the smaller subspecies. The closely related pink-footed goose (A. brachyrhynchus) has the bill short, bright pink in the middle, and the feet also pink, the upper wing-coverts being nearly of the same bluish-grey as in the greylag goose. In size and bill structure, it is very similar to Anser fabalis rossicus, and in the past was often treated as a sixth subspecies of bean goose.

Feeding Habits
Taiga Bean-goose predominantly indulges in a herbivorous diet, focusing on grains, seeds, and occasionally invertebrates. They forage on land, plucking food with their beaks. A notable adaptation is their preference for specific seed types, aligning with food availability throughout seasons.
Habitat
The taiga Bean-goose typically breeds in boreal habitats, favoring lakes, pools, and rivers within the Taiga zone. They show a preference for minerotrophic aapa mires or spruce bogs. In the winter, taiga Bean-goose migrates to more temperate areas, utilizing grasslands, beaches, estuaries, and agricultural landscapes, where they often feed on waste root crops in reclaimed lands. Their habitat range spans broader Arctic and temperate geographical regions.
Dite type
Herbivorous
General Info
Distribution Area
The taiga bean goose is a rare winter visitor to Britain. There are two regular wintering flocks of taiga bean goose, in the Yare Valley, Norfolk and the Avon Valley, Scotland. A formerly regular flock in Dumfries and Galloway no longer occurs there. The taiga bean geese Anser fabalis fabalis wintering in Europe are considered to migrate across three different flyways: Western, Central and Eastern; which has been confirmed by stable isotope analysis of their flight feathers.
Species Status
Not globally threatened.
