The stoat occurs throughout Britain and Ireland, living in any habitat at any altitude with sufficient ground cover and food. The stoat's presence on offshore islands depends upon prey availability. Stoats feed mainly on small mammals, especially rabbits and water voles where these are abundant. Small rodents are also taken, supplemented by birds, eggs, fruit and even earthworms when food is scarce. Stoats don't like to be out in the open and so tend to hunt along ditches, hedgerows and walls or through meadows and marshes.
