description Barnacle Goose Overview

The Barnacle Goose is a medium-sized waterfowl species breeding in Arctic coastal areas of Greenland, Svalbard, and Russia, migrating to winter in northern Europe. Its name derives from a medieval myth claiming the birds emerged from goose barnacles. Adults have distinctive black, white, and gray plumage with a white face. The species feeds primarily on grasses and coastal vegetation.

help Barnacle Goose FAQ

Did medieval people really believe barnacle geese grew from barnacles?

Some medieval European writers claimed the birds developed from goose barnacles attached to driftwood because their Arctic nests were never seen locally. The resemblance between the barnacle's feathery feeding appendages and a small bird helped sustain the story.

Where do barnacle geese actually breed?

They breed in Arctic regions including Greenland, Svalbard, and Novaya Zemlya, then migrate south for winter. Major wintering areas include coastal Britain, Ireland, the Netherlands, and northern Germany.

How can a barnacle goose be distinguished from a Canada goose?

A barnacle goose is smaller and has a mostly white face set against a black neck and breast, with a pale gray barred back. A Canada goose is larger and usually shows a black head with a white chin strap rather than an almost entirely white face.

Why do barnacle goose chicks jump from cliffs?

Many pairs nest on high Arctic cliffs where ground predators have difficulty reaching the eggs. Soon after hatching, the flightless chicks leap toward feeding areas below, relying on their light bodies and down to survive the fall.
