What is the habitat of a polar bear?
Polar Bear Habitat The polar bear’s natural habitat is around the area of the North Pole and some at the Pole itself. Generally, most bears generally inhabit areas below 88 degrees north latitude. They visit Labrador, Newfoundland and Norway annually and visit the Gulf of St. Lawrence and Bering Sea when the ice is thick.
Where do polar bears dig their dens?
Dens are dug in snowdrifts or, in areas farther south, in frozen earth or peat. In the Beaufort Sea area (Canadian and U.S. Arctic), a large proportion of polar bears have traditionally used multi-year ice over, or close to, productive prey denning areas. With a decline in multi-year sea ice in those areas, more bears now den on land.
What factors determine the quality of polar bear habitat?
The type and extent of the sea ice are the main factors that determine the quality of polar bear habitat. The sea ice is where the polar bear’s preferred prey, the ringed seal, lives for all or much of the year; hence, the distribution of bears in most areas follows the seasonal extent of the sea ice. Polar bear habitat varies with the season.
Where do polar bears go in the winter?
