“During the fall, if a polar bear is pregnant, she digs a den into a snow drift. She then climbs into the hole and stays there to give birth and care for her cubs for the first few months of their life. She and her cubs will not emerge from the den until the spring. Male bears and non-pregnant females continue to roam and feed throughout the winter.”
One of the absolute top animals on my list I wish to see in my lifetime.. Guess I need to head up to Svalbard for that!
