Marten, pine
In well-wooded areas or deep forest with plenty of cover, the pine marten (Martes martes) marks out its territory of 10-25 square km. It climbs with great agility but hunts by night on the ground. In northern Europe, the red squirrel is the main mammal in its diet but voles are easier to find. The pine marten frequently nests among the roots of the Scots pine, which is probably the source of its common name. Formerly killed for its fur, the pine marten is now fully protected in Great Britain.

The North American marten is renowned for being the only creature to get the better of a porcupine. Undeterred by the lashing of a spiny tail, the marten circles and confuses the porcupine until it can attack its vulnerable head.
