During summer months, a typical male weighs approximately 250 pounds, while females average slightly over 100 pounds. However, they may double their body weight by the fall. Bears, like humans, are omnivores. Their food intake is 85 percent plant material. They obtain most of their protein from insects, but occasionally eat fawns, or other small animals.
Most bears enter a deep sleep starting in late fall.
Cubs are born in January. Bear sightings usually begin in early March, but weather conditions can delay this. Newborns and mothers remain denned until April. Cubs remain with their mothers for a year and a half. It is illegal to feed or harass any Park wildlife.
