Black bear fur is usually a uniform color except for a brown muzzle and light markings that sometimes appear on their chests. Eastern populations are usually black in color while western populations often show brown, cinnamon, and blond coloration in addition to black. Black bears with white-bluish fur are known as Kermode (glacier) bears and these unique color phases are only found in coastal British Columbia, Canada.
Diet
American black bears are omnivorous: plants, fruits, nuts, insects, honey, salmon, small mammals and carrion. In northern regions, they eat spawning salmon.
Black bears will also occasionally kill young deer or moose calves.
Population
It is estimated that there are at least 600,000 black bears in North America. In the United States, there are estimated to be over 300,000 individuals. However, the Louisiana black bear (Ursus americanus luteolu) and Florida black bear (Ursus americanus floridanus) are threatened subspecies with small populations (see Legal Status/Protection).
Range
The American black bear is distributed throughout North America, from Canada to Mexico and in at least 40 states in the U.S. They historically occupied nearly all of the forested regions of North America, but in the U.S. they are now restricted to the forested areas less densely occupied by humans. In Canada, black bears still inhabit most of their historic range except for the intensively farmed areas of the central plains. In Mexico, black bears were thought to have inhabited the mountainous regions of the northern states but are now limited to a few remnant populations.
Behavior
Black bears are extremely adaptable and show a great variation in habitat types, though they are primarily found in forested areas with thick ground vegetation and an abundance of fruits, nuts, and vegetation. In the northern areas, they can be found in the tundra, and they will sometimes forage in fields or meadows.
Black bears tend to be solitary animals, with the exception of mothers and cubs. The bears usually forage alone, but will tolerate each other and forage in groups if there is an abundance of food in one area.
Most black bears hibernate depending on local weather conditions and availability of food during the winter months. In regions where there is a consistent food supply and warmer weather throughout the winter, bears may not hibernate at all or do so for a very brief time. Females give birth and usually remain denned throughout the winter, but males and females without young may leave their dens from time to time during winter months.
Reproduction
Mating Season: Summer.
Gestation: 63-70 days.
Litter Size: 1-6 cubs; 2 cubs are most common.
Cubs remain with the mother for a year and a half or more, even though they are weaned at 6-8 months of age. Females only reproduce every second year (or more). Should the young die for some reason, the female may reproduce again after only one year.
Height: 2-3 feet (.6-.9m) at shoulders
Length: 4-7 feet (1.2-2m) from nose to tip of tail
Weight: Males weigh an average of 150-300 lbs (68-158 kg), females are smaller. Exceptionally large males have been known to weigh 500-600 lbs .
Lifespan: Average lifespan is around ten years, though black bears can live upward of 30 years in the wild.
