Porcupines also eat certain insects and nuts. In the winter, they mainly eat conifer needles and tree bark. Porcupines are selective in their consumption; for example out of every 1,000 trees in the Catskill Mountains, porcupines will only eat from 1-2 linden trees and one big-toothed aspen.

The crested porcupine is for the most part herbivorous, eating roots, bulbs, and leaves, but occasionally they do consume insects, small vertebrates, and carrion. To ingest calcium and sharpen incisors, they often gnaw on bones. These animals often travel long distances looking for food.
Their diets consist mainly of bark, leaves, and conifer needles, but can also include roots, stems, berries, fruits, seeds, nuts, grasses, and flowers. Some species also eat insects and small reptiles. [2] Their teeth are similar to those of Old World porcupines, with the dental formula 1.0.1.3 1.0.1.3.

"Unfortunately, the decline in porcupines is a bit of a mystery and we are hoping to start working on it soon within the FWP Nongame Program," explained Torrey Ritter, non-game Wildlife Biologist ...
Long-tailed porcupines’ appearances are somewhat rat-like. [4] [5] Their weight is usually around 1.7-2.3 kg but can be as small as 1.5 kg and their length can be between 27.9-48 cm excluding their tail which is usually up to 24 cm. [6] [4] To save themselves from predators including larger mammals, snakes and birds, their tails can be lost when grabbed but will not be regenerated.
Indian porcupines are almost the same size on average as well, being slightly heavier on average than crested porcupine but slightly lighter than Cape porcupines. [5] [6] Cape porcupines measure 63 to 81 centimetres (25 to 32 inches) long from the head to the base of the tail, with the tail adding a further 11–20 centimetres (4.3–7.9 inches ...
