1 Polar bears feed mainly on ringed and bearded seals. Depending upon their location, they also eat harp and hooded seals and scavenge on carcasses of beluga whales, walruses, narwhals, and bowhead whales.  that have hauled out onto the ice. On occasion, polar bears kill beluga whales and young walruses.
Because the polar bear's body requires a diet based on large amounts of seal fat, they are the most carnivorous member of the bear family. Food can be hard to come by for polar bears for much of the year. The bear puts on most of its yearly fat reserves between late April and mid-July to maintain its weight in the lean seasons. The food-free season can last 3 to 4 months -- or even longer in areas like Canada's Hudson Bay.
