Length 58–71 cm (23–28 in), wingspan 120–142 cm, weight 1.5–2.5 kg
Adult

  • Head mostly white (or creamy-white), with black crown, lores, neck and breast.
  • Upperparts are grey, barred black and white.
  • Tail is black, with white upper- and under-tail coverts.
  • Underparts pale silvery-grey, with light barring on flanks.
  • Very short black bill, and black legs.

Juvenile: slightly browner on the wings; as with all geese, body feathering with rounded, not truncated, feather tips, so appears more 'scaly' than 'barred'.

[edit] Similar Species

Cackling Goose has the same size and structure (including the small bill), but plumage differs, being instead like the larger Canada Goose, with brown-grey upperparts and with less white on the face, just a "chin-strap". The smaller Brent Goose lacks any white on the head and has a shorter tail.

[edit] Distribution

Breeds in Greenland, Svalbard (Norway), and Novaya Zemlya (Russia).

Winters in Scotland, especially on Islay (Greenland birds), northwestern Ireland (Greenland birds); around Caerlaverock and Mersehead on the Solway Firth (Svalbard birds), the latter with some overspill in the far north of England (northern Cumbria and around Lindisfarne in Northumberland); and the Netherlands (Novaya Zemlya birds).

Rare vagrant to northeastern North America.

Feral populations also breed widely around the Baltic Sea in Sweden, Finland, and the Baltic States; these birds winter with the Novaya Zemlya population in the Netherlands, with some interchange of individuals. Feral birds also breed in the Netherlands and northern Germany, and a few in southeastern England.

[edit] Taxonomy

This is a monotypic species[1]. Closely related to Cackling Goose.

[edit] Habitat

Marshes, rivers, and estuaries.
Breeds on the rocky coasts of arctic islands.

[edit] Behaviour

Very gregarious in the winter forming large flocks, usually monospecific but occasionally mixed with other geese species.

Migrates late September through October to early November, and late April to May.

[edit] Flight Action

Flocks often closely packed but rather ragged, rather than a V-shaped formation. Strong flight. Wing beats a little slower than Brent Goose, more the rhythm of Greater White-fronted Goose.

[edit] Diet

Their mainly vegetarian diet consists of leaves, stems, roots and seeds of grasses, sedges and other aquatic plants. Supplemented in the winter months by grain and vegetables.

[edit] Breeding

Breeds colonially. The clutch consists of 4-5 eggs which are incubated by the female for 24-25 days; the young fledge 40-45 days later.
