Anybody out there?

This is the time of year that polar bears emerge from their winter dens. In today’s photo, these adorable cubs are peeking out for the first time in their young lives. Polar bears don’t technically hibernate, but during autumn, a pregnant female polar bear will dig a maternity den in the snow (although in some areas it’ll be under the peat soil). While in her small den, the bear enters a dormant state, sleeping nearly all the time, until she gives birth, usually between November and February. Then, in the springtime she’ll dig herself out and emerge with her recently arrived cubs. Polar bear cubs stay with their mother for about two years as they learn to survive in the Arctic.

The cubs in this photo are in Wapusk National Park in Manitoba, Canada, which is known as the ‘Polar Bear Capital of the World’. It’s one of the best places to see polar bears in their natural environment - especially when they move there in autumn, waiting for Hudson Bay to freeze before heading out to hunt for seals.
