Black Bear InformationBlack Bear Cubs at The Memphis Zoo, An Excellent ExhibitBlack Bear Home / Screensavers / Slide Show / Info What does a black bear look like? Black bears are usually black but can have brown noses. Sometime though a black bear can be chocolate or even brown. Most black bears have a white patch on their chests. Black bears have strong, highly curved claws. Adult male black bears range from about 130 to 190 centimeters (50 to 75 inches) in length and weigh 60 to 300 kilograms (130 to 660 pounds). Females measure from 130 to 190 centimeters (50 to 75 inches) and weigh 40 to 80 kilograms (90 to 175 pounds). Black bears vary considerably in size, depending on the quality of the food available. Males may be from about 20 to 60 percent larger than females. At birth, cubs weigh 225 to 330 grams (7 to 11 ounces). Where do black bears live? Black bears are normally found only in forested areas, but within such habitat they are highly adaptable. They live in both arid and moist forests, from sea level to over 2,000 meters (6,560 feet). Historically, black bears are thought to have stayed away from open habitat because of the risk of predation by brown bears. Black bears have become established in the tundra of northern Labrador, a region where there are no brown bears. Black bears are are found mostly in the forested areas of North America. They are presently found in northern Mexico, 32 states of the United States, and all the provinces and territories of Canada except Prince Edward Island. Black bear babies? Females reach sexual maturity at three to four years of age and males a year or so later. Mating takes place in June, July, and August, and pairs may remain together for only a few hours or for several days. Pregnancy last s about 220 days, and the cubs are born in a maternity den in January and February. Litter size ranges from one to five, but two is the average. Cubs may be weaned at six to eight months, but they remain with their mothers for a year and a half. SOCIAL SYSTEM Except for females with cubs, black bears spend most of their time alone. During the breeding season, a male and female may remain together for several days at a time and groups of bears may feed in close proximity to each other if food is abundant, such as in berry patches or at dumps. Female home ranges are 3 to 40 square kilometers (1 to 15 square miles). While the home ranges of individual bears are usually exclusive from those of other bears of the same sex, male ho me ranges are larger and may overlap those of several females. A young adult female is often allowed to establish her territory within that of her mother, while adolescent males must disperse. What do black bears eat? Black bears are omnivorous and eat a wide range of items, depending on what is available. Insects (particularly ants), nuts, berries, acorns, grasses, roots, and other vegetation form the bulk of their diet in most areas. Black bears can also be efficient predators of deer fawns and moose calves. In some areas of coastal British Columbia and Alaska they also feed on spawning salmon
