Weasel standing up on hind legs


Weasels are adaptable little mammals that live almost anywhere they can find cover and prey. This includes sand dunes, grassland, woodland and mountains. They must eat every 24 hours to avoid starvation, so are active both day and night, alternating periods of activity with a few hours of rest. Weasels eat rodents, such as voles and mice for the most part, supplemented by birds or eggs when available. Although they look similar to stoats, one way to tell the difference is that weasels don't have a black tip to the tail.
