How much do black bears weigh?
Cubs weigh only 8-12 ounces at birth and are covered with fine, downy hair. Cubs that weigh 5 pounds or more when they leave the den in the spring have the greatest chance of survival. Adult males and females fluctuate in weight over the course of the year. Adult males can weigh 150-600 pounds, while females with cubs can weigh 90-300 pounds. The heaviest black bear ever killed was killed in NC, 886 pounds. Pregnant females lose about 35% of their weight during the winter, while males and females without cubs lose about 30% of their weight.
