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 in fall, 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 spring 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.
