Wood mouse  (Apodemus sylvaticus)

The wood mouse is the most common native rodent in Britain (2). It has brown fur with a reddish tinge (3) and a white or greyish belly (2). The alternative common name of this species is the long-tailed field mouse, as the tail is often roughly the same size as the combined head and body length (3). This species can be distinguished from the similar yellow-necked mouse as it lacks a yellow collar that forms a bib on the chest (2).
