Branta leucopsis
A striking black-and-white goose once believed to hatch from barnacles.
Size: 55-70 cm | Habitat: Sea, Marsh, Estuary & Shoreline Birds | Season: Winter visitor
With a black head, neck and breast set off by a creamy-white face, the barnacle goose winters in large, noisy flocks on coastal grassland and saltmarsh, chiefly around the Solway Firth and the Hebrides. It breeds far to the north on Arctic cliffs in Svalbard and Greenland.
Black head, neck and breast · creamy-white face · white belly · blue-grey barred back
Barnacle geese graze coastal grassland and saltmarsh in large, tightly packed flocks, moving between roost and feeding sites together. They are among the most sociable and vocal of Britain's wintering geese.
Medieval Europeans, never having seen the bird nest, believed barnacle geese hatched from goose barnacles growing on driftwood — a myth so widely held that some clergy ate the "goose" on fasting days, classing it as fish rather than meat.
The Barnacle Goose (Branta leucopsis) is a strikingly patterned goose, black-headed with a creamy-white face and a blue-grey barred back, wintering in large, noisy flocks on coastal grassland chiefly around the Solway Firth and the Hebrides.
Barnacle geese breed far to the north on Arctic cliffs in Svalbard and Greenland, nesting on ledges to keep goslings safe from ground predators before making a famously perilous jump to the ground days after hatching. The Svalbard-breeding population that winters on the Solway had crashed to only a few hundred birds by the 1940s due to hunting; legal protection allowed a remarkable recovery to roughly 40,000 birds today, one of Britain's clearest goose conservation success stories.
The medieval belief that this species hatched from goose barnacles growing on driftwood, rather than being born like other birds, persisted for centuries simply because no European had ever witnessed an Arctic breeding colony — a reminder of how much natural history depended on direct observation before modern tracking technology.
🟠 Conservation status: Amber (UK Birds of Conservation Concern 5)
Amber-listed, reflecting the international importance of the UK's wintering flocks. The Solway-wintering Svalbard population has recovered strongly from a low of a few hundred birds in the 1940s to around 40,000 today.
