Full Answer

A black bear's weight fluctuates depending on the availability of food. The bears also go into torpor, a state similar to hibernation, during winter. They often lose about 30 percent of their weight during this time. They occasionally eat small game such as fawns, moose calves, and beaver, but 75 to 85 percent of a black bear's diet is vegetation.
