Baby porcupine learns to climb a tree. 2:57
Baby porcupines begin to climb trees once they are two weeks old. They start small and advance to increasingly larger trees. Porcupines use all four limbs and their tail in climbing. Their fore and back paws have long curved claws to catch hold of furrows and crevices in the tree bark. The muscles in their limbs propel the animal upward while the tail, with its stout bristles on the underside, presses against the tree trunk to prevent backsliding. Falling out of trees is a major cause of accidental death among porcupines.
