General Ecology:
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. They search each likely area systematically, often running in a zig-zag pattern. All but the largest prey is killed by a single bite to the back of the neck.
David Attenborough made an excellent programme about them for the BBC called "Stoats in the Priory". He got some spectacular footage of the tiny stoats single-handedly killing and hauling off rabbits, which are three to four times their size and weight.
