Bears living in cold areas in the north hibernate, while black bears in subtropical and tropical areas often don't hibernate. Bears can hibernate for 4-5 months. If you are disturbed during hibernation, you will wake up immediately and occasionally come out of the hole. The cave where bears hibernate is usually chosen in sunny sheltered hillside or dead tree cave. Bears have no fixed habitat except during hibernation. Bears are solitary at other times except during estrus and mating. Female bears usually give birth to 1 ~ 4 cubs.
