The otter is quite common in Kuusamo, as you may notice from the tracks during winter. The animal is mostly mobile at night, and can travel quite long stretches over forest heaths from one water source to another. Their trails with the slides follow the same route from one month to the next.
People are not often aware of the otter that might live in quite small streams. Fish is its main food source, but during wintertime frogs are also important food for otters. They find them from the lake bottoms using their very sensitive whiskers.
