Harvest mice are the smallest British rodent. They are the only Old World mammals to have truly prehensile tails.
Up to 18 months.
Head and body length: 5-8cm, Weight: 5-11g.
They have a blunt muzzle and small hairy ears. The tip of the tail is prehensile (capable of gripping) and is used to assist climbing. The fur is yellow/brown, with a white underside.
They range across Europe (although are absent from most of Scandinavia) E. Russia, Korea, S. China and N. Korea. In Britain, they are found from Yorkshire southwards and parts of Wales.
Harvest mice inhabit hedgerows and reedbeds, and other areas of tall, dense vegetation.
They feed mainly on seeds, fruits and bulbs, but a tiny proportion of their diet is made up of insects, particularly in the summer, as well as roots, moss and fungi. Some food is cached underground for the winter.
