The head and body of the bank vole measure up to 12 centimetres and its tail up to 7 centimetres. Its fur is brownish-red above and pale greyish below. Young voles are paler in colour.
The bank vole inhabits woods, hedgerows and scrub, including shrubberies and rural gardens. It can be found throughout Europe, with the exception of the Iberian Peninsula and the Mediterranean islands.
Active both day and night, the bank vole feeds on fruit, seeds, leaves, moss, fungi and small invertebrates. It climbs well and can often be seen eating fruit on trees and bushes. It breeds several times a year from March to September, and the female bears three to seven young. It is a natural carrier of various diseases.
