Most black bear attacks occur because the animal is frightened or defending its cubs against a perceived threat. Black bears are excellent climbers, so trees offer no refuge. To avoid startling a black bear, it's a good idea to talk, whistle or sing to warn bears of their approach. If you encounter a bear and it has not seen you, leave the area quietly and quickly. If the bear is aware of your presence, avoid making eye contact.
Bears perceive a stare as a threat.
Instead, turn and walk away slowly and quietly while speaking in a normal tone of voice. Don't show fear, run or make sudden movements, Craven warns. Bears' poor vision sometimes makes it difficult for them to identify humans even at close range. In such situations, bears often stand on their hind legs and lift their noses high in the air. This is not a threat, Craven says.
