Yes, the female Polar Bear or "sow" does dig. She will dig to build a den, in big deep snow drifts. The den is usually about the size of a telephone booth, with several small alcoves, where the female may give birth to cubs, if she is pregnant, during the long winter sleep. Females are not the only Polar Bears to take a "winter sleep" or to dig a den. When the temperatures drop and stay constantly low, indicating winter has arrived, all Polar Bears, will make a den, to take a long "winter sleep" in, not to hibernate in. Inside the den, it is about 40 degrees on average, warmer than outside. They are insulated and protected from the extreme temperatures and weather outside. For more details see sites listed below.
