DescriptionEdit

The Barnacle Goose is a medium-sized goose, 60–70 cm long, with a white face and black head, neck, and upper breast. Its belly is white. The wings and its back are silver-gray with black-and-white bars that look like they are shining when the light reflects on it. During flight a V-shaped white rump patch and the silver-gray underwing linings are visible.

DistributionEdit

Barnacle Geese breed mainly on the Arctic islands of the North Atlantic. There are three main populations, with separate breeding and wintering ranges; from west to east:

  • Breeding in eastern Greenland, wintering on the Hebrides of western Scotland and in western Ireland. Population about 40,000.
  • Breeding on Svalbard, wintering on the Solway Firth on the England/Scotland border. Population about 24,000.

Small numbers of feral birds, derived from escapes from zoo collections, also breed in other north European countries. Occasionally, a wild bird will appear in the Northeastern United States or Canada, but care must be taken to separate out wild birds from escaped individuals, as Barnacle Geese are popular waterfowl with collectors.

Ecology, behavior and life historyEdit

Barnacle Geese frequently build their nests high on mountain cliffs; away from predators but also away from food. Like all geese, the goslings are not fed by the adults. Instead of bringing food to the newly hatched goslings, the goslings are brought to the ground. Unable to fly, the three day old goslings jump off the cliff and fall; their small size, feathery down, and very light weight helps to protect some of them from serious injury when they hit the rocks below, but many die from the impact.

Its call is a "kaw".

ConservationEdit

The Barnacle Goose is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. According to Sveriges ornitologiska förening the geese began breeding in Sweden in 71, and according to Skansen it was 40 years ago, more or less, when the entire population of barnacle geese left in the autumn to return in spring, soon after they began breeding in the wild.
