A future written in ice. Polar Bear Week

November marks an important time for polar bears along the shores of Hudson Bay in Manitoba, where they gather and wait for sea ice to form before returning to hunt seals. This annual event is celebrated during Polar Bear Week, observed in early November. Polar bears are powerful swimmers and highly adapted to Arctic life, but shrinking sea ice is forcing many to spend more time on land, making it harder to find food. The mother and cubs seen in today's image represent generations of bears that have followed this seasonal cycle, highlighting both the beauty of the Arctic and the importance of protecting the habitat these iconic Canadian animals depend on.

The tundra vegetation around these resting bears offers shelter while they await freeze-up near Churchill. Classified scientifically as Ursus maritimus, these large marine mammals rely on sea ice as a platform to hunt ringed seals, their primary prey. During the summer and autumn months, the bay loses its ice cover, forcing the local population onto land where they fast for roughly four months. As the ice returns to Hudson Bay, it revitalizes a timeless seasonal cycle, securing the future of these iconic animals and the habitat they depend on.
