Description
Summary:During the summers of 1969 and 1970 polar bears (Ursus maritimus) were observed on North Twin Island (53°20′ N; 80°00′ W), James Bay. Almost all of their time (86.8%) was spent resting. They spent only 3.2% of their time feeding, primarily on geese (Branta canadensis) and crowberries (Empetrum nigrum). There was no difference between the time budgets of lone bears and females accompanied by cubs.
