The adult American Black Bear (Ursus americanus) can grow to weigh 600 lbs but average around 300-450 lbs. Males are around a third larger than females. Smaller subspecies reach only 100 lbs. The black bear cub at birth weighs only 10-14 ounces, but by the time they leave the den for the first time they have grown to 4-8 lbs. The Asian Black Bear (Ursus thibetanus) are generally smaller and adults are typically around 250 lbs. The record is 880 pounds for a black bear killed in NC.
