WEASEL Weasels have long slender bodies which are ideal for squeezing down mouse holes in search of prey. They will often use these mouse holes to sleep in. The Weasel can be found all over mainland Britain, Isle of Wight, Anglesey and Skye. They are absent from Ireland. They can be seen all year round & normally found on farmland, around farm buildings, park land, and waste ground. Anywhere there is food! The weasel eats mice, voles, shrews, small rabbits, birds and birds eggs.
