Pelahatchie Porcupine

Identification

Porcupines (Erethizon dorsatum), sometimes called “porkies” or “quill pigs,” are heavy-bodied, short-legged, slow, and awkward rodents, with a waddling gait. Adults are typically 25 to 30 inches (64 to 76 cm) long and weigh 10 to 30 pounds (4.5 to 13.5 kg). They rely on their sharp, barbed quills (up to 30,000 per individual) for defense.

Range and Habitat

The porcupine is a common resident of the coniferous forests of western and northern North America. It wanders widely and is found from cottonwood stands along prairie river bottoms and deserts to alpine tundra. They favor caves, rock slides, and thick timber downfalls for shelter.

Fun Facts

Young porcupines are capable of eating vegetation within a week after birth, but they generally stay with the female through the summer. Juvenile survival rates are high.

Predators of porcupines include coyotes, bobcats, mountain lions, black bears, fishers, martens, great horned owls, and others.
