Polar Bear Legend of the Great Canadian North - Canadian Wildlife Education Series

Polar Bear Legend of the Great Canadian North - Canadian Wildlife Education Series: "Polar bears naturally balance nature by preventing seal over populations and by leaving food scraps for arctic fox, raven and other bears. Ringed seal is their favorite food though they will hunt other types of seals and occasionally whales and walrus. Their tremendous sense of smell permits them to locate a seals breathing hole up to 1 mile away. Polar Bears walk up to4 miles per hour, while females with cubs slow to less than 2 miles. They use more than twice the amount of energy when walking than other mammals and 13 times more energy than resting bears. They can run up to 25 miles per hour over short distances. Harsh Arctic environments lead to food scarcity. To aid in its survival they slow their metabolism down after 10 days without food. This allows the bear to conserve energy until food is available. Hungry bears have been known to swim up to 6 miles per hour for up to 56 miles, though this quickly depletes their energy. When food is abundant its territory is small.
