Tundra Bean Goose

Identification

The tundra bean goose is a medium-sized goose measuring 68 to 90 cm in length, with a wingspan of 140 to 174 cm. The most distinctive feature is its bill, which is black at the base and tip with a bright orange band across the middle; the legs and feet are similarly bright orange. The upper wing-coverts are dark brown with narrow white fringes to the feathers, distinguishing it from the white-fronted and lesser white-fronted geese. The tundra bean goose produces a loud, honking call that is higher-pitched in smaller individuals.

Two subspecies exist: the smaller A. s. rossicus from the northern Russian tundra, which has a short, stubby bill with a narrow orange band, and the larger A. s. serrirostris from the East Siberian tundra, which has a longer, stouter bill. The closely related pink-footed goose differs noticeably in having a short, bright pink bill and pink feet, along with bluish-grey upper wing-coverts.

Range & Habitat

The tundra bean goose breeds in northern Siberia, with the nominate subspecies ranging across the northern Russian tundra east to the Taimyr Peninsula, while the larger subspecies inhabits the East Siberian tundra. This species is highly migratory, moving south across Asia during winter months. Unlike many goose species, the tundra bean goose has no regular wintering sites and instead appears in small groups scattered among other grey goose species across its wintering range.

Behaviour & Diet

As a migratory species, the tundra bean goose exhibits the typical seasonal movements of high-Arctic breeding geese, traveling between its breeding grounds in Siberia and wintering grounds further south in Asia. The species often occurs in mixed flocks with other goose species during winter, suggesting flexible social behaviour and habitat use. Like other bean geese, it is likely an herbivorous grazer, though specific dietary details are not extensively documented in available sources.

Best Time & Places to See It

The tundra bean goose has no regular wintering sites, making it an unpredictable visitor across most of its range. However, among the most reliable localities are WWT Slimbridge in Gloucestershire and Holkham Marshes in Norfolk, both in England, where small groups are occasionally encountered alongside other grey goose species. Winter months are the most likely time to encounter this species outside its breeding range, though sightings remain irregular and require patience and luck.

Photography Tips

Photographing the tundra bean goose is challenging due to its unpredictable presence and tendency to appear in small numbers within mixed flocks. Focus on capturing the distinctive orange bill and legs, which are the key identifying features separating this species from similar geese. When visiting known localities like Slimbridge or Holkham Marshes, scan mixed goose flocks carefully during winter months. Patient observation and familiarity with the subtle differences from related species will improve your chances of both identifying and photographing this elusive Siberian breeder.
