Black Bears are born tiny, helpless, and hairless, weighing less than half a pound. A mother bear will typically give birth to one to three cubs at a time. By the time a mother bear and her cubs are ready to emerge into spring, the cubs typically weigh around five pounds.Young bears grow very quickly and can weigh around 80 pounds by their first birthdays. Cubs will remain with their mother for about 18 months or until she is ready to mate again.
