The tiny harvest mouse lives in long tussocky grassland, reedbeds, hedgerows, farmland and around woodland edges. It is mainly vegetarian, eating seeds and fruits, but will also eat invertebrates. Harvest mice build a spherical nest of tightly woven grass, high-up in the tall grasses, in which the female will give birth to around six young.
