Bears are very intelligent and curious. Sometimes this natural curiosity and opportunistic feeding habits cause them to lose their fear of human activities. The result is a nuisance bear, which could pose a threat to humans. Occasionally black bears can be relocated successfully, often many miles from the area where they were creating a problem. But often these nuisance bears must be destroyed.
Bears habituate quickly to humans and their food.
Once a bear has found how simple it is to obtain garbage or food from humans a problem bear can quickly develop. Many national and state parks across the country have to deal with problem bears on a daily basis. Bears are powerful, and super smart, they have been documented tearing doors off cars, entering camps and tents, and even in houses in search of food. Goat and sheep kills are far more common than calves or young horses. Bears also feed on carrion and are often blamed for livestock kills they actually did not make.
