The Bank Vole (Myodes glareolus), is a small vole with red-brown fur and some grey patches, with a tail about half as long as its body. It lives in woodland areas and is around 100 millimetres (3.9 in) in length. It is found in western Europe and northern Asia. It is native to Great Britain but not to Ireland, where it has been accidentally introduced. The bank vole lives in woodland, hedgerows and other dense vegetation such as bracken and bramble. It can live for 18 months and is omnivorous, eating insects, leaves and fruits such as raspberries and hazel nuts. It readily climbs into scrub and low branches of trees.
In areas such as mainland Great Britain where the only other small vole is the Field Vole (Microtus agrestis), it can be distinguished from that species by its more prominent ears, chestnut-brown fur and longer tail.
Bank voles live in underground chambers lined with moss, feathers and vegetable fibre. Inside the chamber they keep a store of food.
