Juvenile field mice are less red in colour than adults, and are greeny-brown on top and whitish-grey underneath.  They have a short lifespan, as adults rarely survive winter.  It has a varied diet, feeding on what it finds in its surroundings. It eats seeds, fruit and berries, the roots and branches of young plants, as well as all sorts of insects (centipedes, caterpillars) and snails.  Its spends the night looking for food, and rests during the day in a nest of leaves and grass, whose depth depends on the temperature outside.
