Stone martens are a species native to Europe and Asia.
They were released in southern Wisconsin in the early 1970s, where they've established a breeding population. Habits Little is known about the habits of pine martens because they're most active at night. They'll pursue prey, such as red squirrels or chipmunks, up a tree and may climb trees to avoid danger. Martens move across the ground in a zig-zag fashion, often followed by a series of jumps. They're solitary but curious animals.
