Black Bear Cub
Despite the size of fully matured black bears, their cubs are rarely larger than a pound at birth. Black bear cubs are typically blind for up to 4 weeks, and can begin walking at 5 weeks. Until they’re about a year and a half old, cubs rely on their mothers for everything, including food, protection, transportation, and warmth. In fact, motherhood for a black bear is so demanding that they typically lose a third of their bodyweight caring for their young during the winter months. Talk about motherly dedication!
