Black bears are generally shy and reclusive animals. They avoid human contact and are not normally agressive towards people. The only exceptions to this are so called "park bears" which are fed and lose their natural fear of humans. Although they are classified as carnivores, black bears are actually omnivorous, eating many types of plant and animal material. Grasses, green leaves, and other plants are eaten by black bears in the spring after they emerge from their winter dens. Summertime provides them with various berries, fruits, and insects. In fall and early winter, acorns and other nuts are especially sought after in order to build up fat reserves for the winter. In our area, black bears don't hibernate but they may be dormant during the coldest part of the winter. Unlike true hibernators, a dormant black bear can become fully alert in minutes if it is disturbed. Winter dens include hollow trees, cavities formed in the ground, or sometimes simply a bed on the surface of the ground in a thicket. Females give birth to their cubs during the winter in late January or early February. Average litter sizes are from two to three young. The young bears stay with the mother through the next winter and disperse the following spring. Female bears usually begin breeding at about 3 to 5 years of age and normally produce cubs only every other year. Black bears require extensive amounts of land with little disturbance by man, a major limiting factor in their numbers. Male bears tend to roam much more than the females. Studies have shown that the home range of female black bears in the coastal plain average about 2,000 acres with males averaging about 11,000 acres. Female black bears in the mountains roamed over 2,800 acres while males in the mountains utilized over 15,000 acres. Oak, hickory and mixed hardwood forests with laurel and rhododendron thickets are preferred bear habitats in the mountains. In the coastal plain they are found primarily in swamps, pocosins, and lowland hardwood forests. Black bears live to be about 10 years old.

Unlike Black and Grizzly bears which are primarily nocturnal the Polar Bear may be active at any time of the day or year searching for prey on long summer days and sometimes on long winter nights. Adaptations to its Arctic habitat include its fur color which blends with the snowy environment and so provides useful camouflage for capturing prey; its large size which helps maintain body temperature by reducing surface-heat loss; and its furred feet which insulate against cold and provide traction on icy surfaces. Because the hairs of its waterproof coat are hollow they are especially insulating and increase the bear's buoyancy when swimming. An excellent swimmer it paddles at about 6 1/2 mph (10 km/h) with the front feet only hindfeet trailing-a trait unique among four-footed land animals-and can remain submerged for about two minutes. While swimming or treading water it stretches its long neck for a better view as it does on land. Owing to the scarcity of plants in its icy habitat the Polar Bear is the most carnivorous North American bear with canine teeth larger and molariform teeth sharper than those of other bears. An acute sense of smell enables the Polar Bear to locate prey even when it is hidden by snow drifts or ice. It stalks young seals and Walruses and sometimes adult seals often by swimming underwater to their ice floes. While hair seals are its staple it also feeds on fish birds bird eggs small mammals dead animals (including whales) shellfish crabs starfish and mushrooms grasses berries and algae when available. The Polar Bear hollows out a winter den in a protected snowbank where it retires in a lethargic condition. Females den from November to March during which time they give birth.

A polar bear carcass found on the Arctic island of Svalbard the northernmost part of Norway has shocked experts who say climate change may be to blame for the animal's death.

The starved polar bear in Norway was said to be in good health in April when the Norwegian Polar Institute examined and tagged it. However the animal was reduced to skin and bones by the time a group of explorers happened upon its body in July.

"From his lying position in death the bear appears to simply have starved and died where he dropped" polar bear expert Dr. Ian Stirling an adjunct professor at the University of Alberta told The Guardian. "He had no external suggestion of any remaining fat having been reduced to little more than skin and bone."

Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals. That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April.

Arctic sea ice reached a record low in 2012 according a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change.

The International union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species.
