Scientists with Environment Canada say polar bears are increasing their intake of eider duck eggs, according to CBC News. Across northern Canada, the bears are feasting on the eggs as their other natural food sources become more scarce. The scientists attribute this to the receding Arctic sea ice.

Polar bears travel across the arctic sea ice in northern Canada each winter to hunt seals, their primary food of choice. However, each year the ice takes longer and longer to form, according to The Alaska Dispatch. The Polar Science Center at the University of Washington has studied the polar ice cap for years, and shows that today it is at half the volume it was in 1979.

As the polar bear population depends on the arctic sea ice for its winter hunting grounds, it will have to go find a new food source in order to survive, just hopefully not the eider duck eggs.

Churchill, Manitoba, the self-titled "Polar bear capital of the World," is a perfect place to see the bears in the wild. Thousands of them migrate through the town area on their way to the Hudson Bay, and with the ice forming later each year, the bears linger for longer.
