4. Home Range The area an animal travels in its normal activities. They have enormous home ranges, covering very large distances while gathering food, mating and caring for young.

5. Distance Covered An individual polar bear may cover an area equal to 259,000 square kilometers during its lifetime. The distance covered changes year to year due to ice conditions and seal populations.

6. Food Sources Polar bears are meat eaters, while on the ice their diet consists of mostly seals. They can go weeks between meals.

7. Summer and Fall Months After the ice has melted polar bears are stranded on land. During this time they have limited food sources. They scavenge the shoreline for bird eggs, rodents, berries and anything else that is edible.
