Pine martens are about the size of a cat, with a dark brown head and large ears, creamy-white throat and brown fur.

Once widespread in Britain, they are now to be found mostly in remote, forested areas of Scotland after years of persecution and habitat loss wiped out the pine marten elsewhere.

In their native habitat, male martens have quite a large territories (around 1500 hectares) but they have also adapted to live in commercial forestry plantations.
