North American Porcupine

North American Porcupine

Welcome to the Abilene Zoo’s webpage dedicated to the fascinating North American Porcupine! The North American Porcupine (Erethizon dorsatum) is the second-largest rodent native to North America and is best known for its unique quills. Visit our Woodlands exhibit to observe these incredible animals up close. Let’s explore their diet, habitat, size, and conservation status, as well as some fun facts that make them truly special.


North American Porcupines are primarily herbivores, feeding on a wide variety of plant materials. Their diet consists of leaves, twigs, bark, and buds from trees such as aspen, willow, and cottonwood. They also consume fruits, nuts, and various types of vegetation. During the winter months, when fresh vegetation is scarce, they rely more on the bark and cambium layer of trees for sustenance.


These porcupines inhabit a wide range of habitats throughout North America, including forests, deserts, and grasslands. They can be found from Alaska and Canada, all the way down to northern Mexico. North American Porcupines are skilled climbers and are often found in trees, where they can safely forage for food and evade predators.

Size and Weight

North American Porcupines are relatively large rodents, with adults measuring between 25 and 36 inches (64 to 91 cm) in length, including their tails. They typically weigh between 12 and 35 pounds (5.4 to 15.9 kg), with males being slightly larger than females.

Conservation Status

The North American Porcupine is currently listed as “Least Concern” on the International Union for Conservation of Nature (IUCN) Red List. Their population is stable and widespread, and they face few significant threats. However, habitat loss and human-wildlife conflict can pose challenges to local populations in some areas.

Intriguing Facts

Quill Defense:

The most recognizable feature of the North American Porcupine is its quills, which are modified hairs coated with keratin. There are about 30,000 quills covering its body, providing an effective defense against predators. Contrary to popular belief, porcupines cannot "shoot" their quills, but they can detach easily when touched.

Nocturnal Lifestyle:

North American Porcupines are primarily nocturnal animals, which means they are most active during the night. They spend their days resting in trees or other secluded areas and forage for food during the night.

Swimming Abilities:

Despite their seemingly ungainly appearance, North American Porcupines are actually excellent swimmers. Their hollow quills help them stay buoyant in the water, allowing them to easily navigate rivers and lakes in search of food.

Solitary Creatures:

Porcupines are typically solitary animals, with the exception of the mating season and when mothers are raising their young, known as porcupettes.

Unique Vocalizations:

North American Porcupines have a range of vocalizations, including grunts, whines, and even a high-pitched scream when threatened. These vocalizations help them communicate with other porcupines and ward off potential predators.
