polar bears: mother nursing cubs

Rigged with a live camera, the Tundra Buggy roves the tundra tracking polar bears and other native species during daylight hours.

Every Fall, Churchill’s polar bears gather along the shores of Hudson Bay to wait for the ice to form so they can return to their seal-hunting grounds. During that time, they’re in a state known as walking hibernation.

But freeze-ups are coming later each year—and melt-offs sooner—straining the limits of their fat reserves. That’s why this population is considered the most endangered. It’s up to us to take action to help them.
