The wintering goose populations are found in Ireland, United Kingdom, Netherlands, Belgium, France, Germany, west Denmark and southern Norway.

Vagrant goose is seen in Canada, United States, Switzerland, Spain, Portugal, Italy, Turkey Hungary, Austria, Serbia, Algeria, Morocco, Egypt and Tunisia.

The Important Bird and Biodiversity Areas (IBA) of the barnacle goose species in Iceland are, Svarfadardalur, Hóp-Vatnsdalur and Hestgerdislón-Hornafjardarfljót. The IBA in Germany is Jadebusen.

The IBA of the barnacle goose in Greenland are, Germania land, Enhjørningens Dal, Pingel Dal, Kjoveland, Heden, Hochstetter Forland, Ørsted Dal, Østersletten and Knudshoved and and Slaedelandet.

Some of the IBA of this barnacle goose in United Kingdom are, Upper Solway Flats, Uists Machairs, Tiree and Coll, South Walls, Shiant Isles, Rinns of Islay, Monach Islands, Loch of Strathbeg and Lindisfarne.

Ecosystem and habitat

The barnacle goose species does not normally occur in forest. It normally occur in altitudes from 0 to 100 meters. The artificial ecosystems and habitats of the goose species include the pasturelands.

The natural ecosystems and habitats of the goose species include Arctic semi-desert tundra, tundra grasslands, marine mudflats, intertidal rocky shores, intertidal marshes with emergent grasses and tidepools.

Diet and feeding behavior

The diet of this barnacle goose species consists mainly of plant matter. Grasses, sedges, leaves, stems, seeds, aquatic plants (del Hoyo et al. 1992), agricultural grain and vegetables are their primary food.

Reproduction and breeding habits

The breeding season of the barnacle goose species is from May to July in most of their breeding range. These species are monogamous and pair for life. They breed in small dense colonies.

The nesting sites include rocky ground (del Hoyo et al. 1992), rocky outcrops, steep cliffs and tops of low hills. The nest is shallow depression on a mound of vegetation. The clutch contains 4-6 eggs.

The female bird incubates the eggs. The chicks hatch out after 24-26 days. The hatchlings are precocial and leave the nest and feed themselves. The chicks fledge after 40 to 45 days. The young are protected by the parents.

Migration and movement patterns

The barnacle goose species is a fully migratory bird. The breeding populations occurring in Arctic islands migrate southwards to the wintering grounds in September.

The winter is spent in the coastal areas of west Europe. The return migration begins in April. The barnacle goose species spends about 30 days in spring staging areas for feeding, before migrating to the breeding grounds.
