Ynghylch

The wood mouse is sometimes known as the long-tailed field mouse and is widespread; it is probably most common in woodland, rough grassland and gardens. It is mostly nocturnal and an agile climber. Wood mice will gather food stores of berries and seeds in the autumn, which they keep in underground burrows or sometimes in old birds' nests. Females have up to six litters a year of between four and eight young, and may even breed over winter if food is abundant.

The wood mouse is our commonest mouse and the one you are most likely to find in your garden. Because of this, it often falls prey to domestic cats, foxes and owls; in fact, tawny owls may not breed if wood mouse numbers are low as it restricts their diet.
