Length 58â€“71 cm (23â€“28 in), wingspan 120â€“142 cm, weight 1.5â€“2.5 kg
Juvenile: slightly browner on the wings; as with all geese, body feathering with rounded, not truncated, feather tips, so appears more 'scaly' than 'barred'.
 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. Barnacle Goose also occurs in a rare mostly white mutation (leucistic or partial albino) which may be confused with Snow Goose or Ross's Goose.
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).
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.
Marshes, rivers, and estuaries.
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.
 Flight Action
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.
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.
Short, sharp barking notes, given on ground and in flight, not unlike the yapping of a small dog.
