Size and color
The wood mouse has a sandy-brown coat and large ears and eyes. The under parts are white, with a yellow streak on the chest, and the tail is slightly hairy. It has large hind feet which help it to leap about. The wood mouse is about 7.5-11cm long, not including its long tail, and it weighs 20-30g.
Wood mice dig their own burrow systems, where they store food and spend the day and where the young are born in a nest chamber, which is lined with leaves, moss and grass.
Wood mice eat a wide range of seeds from grasses, herbs and trees, as well as buds, shoots, berries and fungi. They also eat insects, worms and slugs.
