The common porcupine is a herbivore. It eats leaves, herbs, twigs and green plants like clover and in the winter it eats bark of the trees. The North American porcupine climb on the trees to find food. The African porcupine are not the climbers, they roam on the grounds. Porcupines live in forests, deserts, rocky outcrops and hillsides. Some New World porcupines live in trees, but Old World porcupines stay on the rocks. Porcupines can be found on rocky areas up to 3,700 m (12,100 ft) high. Porcupines are generally nocturnal but are occasionally active during daylight.
