The stoat is a small predator from the weasel family. It changes its fur color from brown in summer to white in winter, except for the black tip of the tail.
The stoat differs from the weasel in its larger size and black tail tip. It is important for nature because it eats many rodents and helps maintain balance in forests and fields.
