Pine Martens.

Pine Martens are a rare and elusive animal which is mostly found in the North of Britain. They prefer wooded areas, they climb well and live in holes in trees, such as old squirrel dreys.  They feed on small rodents, birds, eggs insects and fruit, they can be encouraged to visit bird tables. Despite looking in Scottish woodlands and forests I have not seen one in the wild. This captive animal is in the New Forest Animal Sanctuary.
