In the wild, black bears live primarily in  eastern forests, swamps, and western forests and wooded mountains.  You  rarely spot them higher than 7,000 feet.  Their range is extensive:  Most of Canada, south on the West Coast through northern California, in Rocky  Mountain states to Mexico, north MN, WI, and MI in New England, NY and PA  through the Appalachians; in the Southeast, most of Florida and southern Louisiana.
The black bear is omnivorous which means it eats vegetables, fruit,  breads and meat.  During autumn, they eat more than usual to gain body fat to sustain them through  their winter "hibernation".  Bears do not hibernate, but rather fall into a  deep sleep from which they can awaken quickly.  When food is abundant, they  will eat up to 45 lbs. a day and put on 5 lbs. per day in preparation for  winter.  During "hibernation", the bear may only eat once a week, or if it  is very cold he will not eat for a month.  While "hibernating", the black  bear does not urinate or defecate.  Bear Country participates with  researchers at the University of Illinois in a project to study how the bear  recycles toxins during "hibernation" with the hope of helping people with kidney  disease and osteoporosis.
Breeding season is in late June to early July.  The fertilized  egg matures to the blastocyst stage and goes dormant Blastocyst will not  implant in the uterus until late November.  In early December, embryo  development proceeds normally. Birth occurs in late  January.  Gestation is approximately 7 months.  The delay in gestation  is approximately 5 months and true gestation is approximately 8 weeks.  A  black bear usually has between 1 to 5 cubs.
The cubs are born during the "hibernation period" in late  January.  When they are born, they weigh about nine ounces and are the size  of a stick of butter.  From then on, they grow very quickly.   By May they can be 12 to 20 pounds. The cubs  weight will increase to about 75 pounds by the end  of the summer.  An adult male can weigh as much as 650 pounds, but usually  is about 450 to 500 pounds at full weight. The female will reach a maximum  weight of almost 400 pounds.
The black bear's name is deceptive.  It is a species name and  does not refer to their color.  They can range from pure black to cinnamon  to blonde.  Black bears in the East  are nearly black, while those in the West are black to cinnamon with a white  blaze on their chest.  The black bears in Alaska can have a blue or white  color phase to blend with their snowy surroundings.
Black bears are similar to hogs and are even named the same--males  are boars and females are sows, but babies are called cubs.  They can live  to be about 25 years old.
