DESCRIPTION

At times I can make a bit of a mess. What can I say … I’m a rodent. I gnaw the bark off trees and I’m particularly fond of White Pine. With incisor teeth that never stop growing I must always have something to chew on. I also have a weakness for the salt and glue found in plywood. I am also the one who gnaws on antlers that have fallen on the ground – it’s how I get my calcium.

I lead a solitary life except in winter when I’m likely to share my den and food with other porcupines. I do not hibernate. I am active during the winter. When I move along the ground I leave wide ruts which make it easy to track me. I am a very good climber and I’ll often spend the night in a tree.
