Ynghylch

The bank vole lives in woodland, hedgerows, parks and gardens. It eats fruit, nuts and small insects, but is particularly keen on hazelnuts and blackberries. Bank voles are very active and agile animals, and are frequently seen - they even visit bird tables. They live in shallow burrows, but may make grassy, round nests above ground if the soil is unsuitable for digging. They have three or four litters a year, each with three to five young. Bank voles do not hibernate.

What to look for

The bank vole is rich, chestnut-brown above, and white below. It is richer in colour than the similar field vole and has a proportionally longer tail. Voles have blunter, rounder faces, smaller ears and eyes, and shorter tails than mice.

Where to find

Widespread, absent from most of the Channel Islands, the Isles of Scilly, most Scottish islands, Northern Ireland and the Isle of Man.
