Genus
The waterfowl genus Anser includes all grey geese and sometimes the white geese. It belongs to the true geese and swan subfamily (Anserinae). The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer. Some also breed further south, reaching into warm temperate regions. They mostly migrate south in winter, typically to regions in the temperate zone. Numerous fossil species have been allocated to this genus. As the true geese are near-impossible to assign osteologically to genus, this must be viewed with caution. It can be assumed with limited certainty that European fossils from known inland sites belong into Anser. As species related to the Canada Goose have been described from the Late Miocene onwards in North America too, sometimes from the same localities as the presumed grey geese, it casts serious doubt on the correct generic assignment of the supposed North American fossil geese. The Early Pliocene Branta howardae is one of the cases where doubts have been expressed about its generic assignment.[citation needed] Similarly, Heterochen = Anser pratensis seems to differ profoundly from other species of Anser and might be placed into a different genus; alternatively, it might have been a unique example of a grey goose adapted for perching in trees.
Physical charateristics
Medium-sized, rather compact, rather short-billed and short-necked, essentially pinkish-grey goose, with dark, round head and foreneck and pale forewing obvious in flight. Bill marks and legs pink.

Habitat
Concentrated largely in the Atlantic sector of west Palearctic. The presence in breeding habitat (up to 700 m above sea) is limited to brief and uncertain ice-free period. Strict attachment to parts of apparently suitable terrain, at mean densities above 130 nests per square km. Preference in Iceland for inaccessible nest-sites in river gorges suggests safety from ground predators is a primary requirement. Apparent inconsistency of wide-spread grouping of oasis nests on low heathy mounds or ridges perhaps due to relative failure of such predators to reach these seasonally uninhabitable uplands. In Spitsbergen, where predation of Arctic Fox is minimal, nest on flat ground or grassy slopes when snow-free at laying time, as well as low cliffs and rock outcrops.
Reproduction
Egg-laying in Iceland from early or mid-May, in Spitsbergen laying starts last half May and completed first half June. The nest is build in low hummocks and banks snow-free at time of building, and above post-thaw floods. Also tops of rock outcrops, ledges on river gorge cliffs, and tops of rock pinnacles in gorges. The nest consists of low mound of grasses, sedges and other vegetation, with shallow cup. Large amounts of down added during and after laying. Clutch is usually usually 3-6, incubation lasts 26-27 days and the goslings will flegde after about 56 days.
Feeding habits
Vegetable material, including parts of plants both above and below ground. Feeds like Greylag Goose, though much less commonly in water, and smaller Bill and gizzard tend to restrict it to softer material. In summer quarters, eats green parts, roots, and fruits of wide variety of tundra plants. In winter quarters, now feeds mainly on farmland, including grassland, but exact composition of diet differs according to local, seasonal, and annual variations in crop-plant availability.

Conservation
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Anser brachyrhynchus breeds only in Svalbard, Iceland and east Greenland, with the
entire global breeding range hence confined to Europe. The European breeding
population is relatively small (<69,000 pairs), but increased substantially between 1970-1990. All three populations continued to increase during 1990-2000, and the species underwent a moderate increase overall.
This goose has two distinct populations. Both have undergone an important increase since the 1950’s. The first population is breeding in Iceland and Greenland, and wintering in Scotland and northern England. It amounts to 225000 individuals. The second population is breeding on Svalbard and wintering in Denmark, the Netherlands and Belgium. It amounts to 34000 individuals

Migration
Migratory, Greenland and Icelandic populations winter mostly in Scotland and N and E England; Svalbard birds winter along E shores of N Sea. Sporadically in more southern latitudes during cold winters.
