The
wood mouse (
Apodemus sylvaticus) is a common murid
rodent from Europe and northwestern Africa. It is closely related to the
yellow-necked mouse (
Apodemus flavicollis) but differs in that it has no band of yellow fur around the
neck, has slightly smaller ears, and is usually slightly smaller overall: around 90 mm (3.54") in length. It is found across most of Europe and is a very common and widespread species, is commensal with people and is sometimes considered a pest. Other common names are
long-tailed field mouse,
field mouse,
common field mouse, and
European wood mouse.
