They feed on small rodents, birds, eggs insects and fruit, and although rare, can be encouraged to visit bird tables. During the mating season, pine martens make shrill, cat-like calls. In the spring, they have litters of 3-5 young, which are independent by summer.

  • Bilberries can make up to 30% of a pine marten’s summer diet resulting in the droppings turning blue in colour. The species use regular latrines, usually on boulders or logs that are in conspicuous spots. When they’re fresh, droppings may have a slimy appearance due to mucous binding them together. They may contain fur, feathers, bones or seeds.
