This tiny mouse weighing the same as a two pence coin favours a habitat consisting of long grasses, reedbeds and hedgerows. It's mostly associated with farmland and the harvest, although it can be seen all year round.
Harvest mice build small tightly bound round nests which are situated high in the grasses. They are the only British mammal to have a prehensile tail, meaning it can use it as a fifth limb, helping it to climb and hold onto grass stems.
Do you know that the harvest mouse is protected from deliberate cruelty under the Wild Mammals (Protection) Act.
