The European pine marten (Martes martes) is a small, agile carnivore native to the woodlands and forests of Europe, from the British Isles and Iberian Peninsula to Scandinavia and Eastern Europe. It has a slender body, a bushy tail, and soft brown fur with a distinctive creamy-yellow throat patch. Pine martens are excellent climbers and primarily nocturnal or crepuscular, hunting squirrels, birds, small mammals, insects, and also eating fruit and carrion. Solitary and territorial, they shelter in tree hollows or old buildings. Once heavily persecuted, pine marten populations are now recovering in many areas and are listed as Least Concern, though still locally threatened by habitat loss.
