Martens are carnivores which mainly hunt at night. They have thin bodies, long, bushy tails, short legs and pointed faces. Their fur is usually brown with pale chest. Martens live in forests. They have claws that retract, like cats, so they can easily climb trees. They live by themselves and do not like other martens living too close to them. They eat mostly small mammals like squirrels, voles, mice, rabbits, but also fish, insects, eggs and sometimes fruits (mostly berries) when available.
