In areas without salmon, bears rely on vegetation and berries throughout the year, especially blueberries. Ants, grubs, and other insects help to round out the black bear's diet. Behavior Black bears have adequate senses of sight and hearing and possess an outstanding sense of smell. Bears are extremely powerful animals and potentially dangerous to humans. They are usually highly cautious and secretive, but if they have a food supply or young, they become defensive against all intruders.
Every year bears encounter humans, especially near garbage dumps and fish drying racks.
