Each quill is marked with black and white bands. Some quills can be up to 20 inches 51 centimeters long. These long, pliable quills act as guard hairs and form a "skirt. These can stab any potential threat. At the base of the tail, the porcupine has blunt, hollow quills that rattle when shaken, serving as a warning to potential predators.
If the noise doesn't work, the porcupine may try to charge backward into the predator. When threatened, a crested porcupine stamps its feet, growls, and grunts to scare off the predator. The quills of New World porcupines are much smaller about 4 inches or 10 centimeters long but work just as well. The end of each quill has a small barb like a fish hook that snags the flesh, keeping the quill stuck in the enemy's skin.
Any animal with a quill lodged in its skin will have a hard time removing it if it doesn't have fingers and thumbs! When threatened, New World porcupines erect quills that jut out in various directions, like a pincushion. The porcupines may stand still in a defensive pose, or they may charge the enemy.
New World porcupines are also known to lash out at predators by batting at them with their quill-laden tails. During fights, New World porcupines also chatter their teeth to sound fierce. Porcupines cannot shoot their quills! Quills are just modified hairs made out of keratin, the same substance found in our own hair and fingernails.
The quills do not cover the underside of the porcupine. Porcupines have muscles at the base of each quill that allow them to stand up when the porcupine is excited or alarmed. Like all hairs, quills do shed, and when the porcupine shakes, loose quills can fly off but without deadly force. Still, the quills can cause problems, and puncture wounds inflicted by porcupines are serious.
If the animal girdles a tree — chews all the way around the trunk, interrupting the flow of water and nutrients — the tree may end up deformed or dead. In the spring, porcupines expand their diet to buds and twigs as well as herbaceous plants, fruits and nuts.
Based on this diet, you could infer the porcupine's favorite habitat: mixed conifer-hardwood forests and woodlands. They may also be found in shrubland and forested swamps, and even in the desert in parts of their range. Porcupines are usually solitary, except for mothers with young. A female porcupine will begin breeding at 15 months and will have a single precocious offspring each year in late spring.
The baby is born fully formed with open eyes and a full set of teeth. Even its quills, which are soft at birth, harden within an hour. Porcupine young are able to climb soon after they are born; their feet have long curved claws.
And even though they can eat solid food immediately, they will nurse for four months. In the winter, a group may share a den, in a hollow tree, downed log or rock outcropping. Porcupines do not hibernate; they are active year-round. The porcupine is not globally rare or a federally listed species. Meet the people trying to help.

The Porcupine looks most like a prickly beaver! Its long strands of brown hair looks soft, but thousands of quills are tucked inside. The longest quills are found on their back and behind, while the shortest ones are on their face. Each quill is hollow — it is yellowish in colour, with a black tip and is covered in tiny barbs. Roughly 30, quills cover the whole body except for the stomach, nose and bottom of their feet. The porcupine has a small face, small ears, short legs and a thick, small tail.
Its flat feet and sharp, rounded claws make it well adapted to climbing trees. Porcupines rely heavily on smell as they are short-sighted. Porcupines stick close to the trees. Beyond forests, you may find them alongside river undergrowth and maybe in the trees by a rocky ledge. They live in dens found in rock piles, caves, fallen logs and trees. Generally, they stay close to home leaving their dens for food — porcupines eat a variety of shrubs, bark, water plants and they love anything salty.
It will tuck its head in, lean forward and thump its back feet while swinging its tail as a warning. Sometimes loose quills fly out of the tail or if a predator tries to get too close, the quills will stick them. The quills are an amazing defense mechanism — when they get lodged in the skin, body heat makes the barbs swell, making it even harder and more painful to pull them out.
Animals like bears, bobcats, lynx , wolves and coyotes have also been known to be big predators, but the biggest of them all is the fisher.
