Information
Description : 

Large ears and protruding eyes, together with dark sandy brown upper parts and white under belly, with a long tail.

Distribution : 

The Wood Mouse is found throughout the British Isles.

Habitat : 

As the name implies the Wood Mouse is likely to be found in woods, but is also adept at thriving on moorlands, in gardens and buildings - in fact, almost anywhere! They make their homes in tunnels under ground which they also use for storing food. These tunnels may be used by several generations of Wood mice.

Predators : 

Domestic cats, foxes and weazels prey on the Wood Mouse, as do owls. The Tawny Owl may not breed if Wood Mouse numbers are low, therefore restricting the owl's diet.

Reproduction : 

The Wood Mouse has only 1 or 2 litters per year, between March and October and they give birth to between 4 and 7 pups. They sometimes nest in trees and properties, but also tunnel beneath the ground to build nests, which are sometimes shared with other Wood mice, out of the breeding season.

Status : 

Numbers are lower at the end of the Winter, but once breeding begins numbers increase considerably.

Did You Know?: 

The Wood Mouse is usually nocturnal and has a good night vision and an acute sense of smell. Of all British mammals, the Wood Mouse is probably the most abundant and widespread.

Images of Tracks : 
Tracks Description: 

Woodmouse burrows are more often found in the open than those of Voles,which tend to be in, or on the edge of cover. The tunnel systems of their burrows are also deeper underground than those of Voles,often going down to a metre or more. The image above is of a burrow in the centre of a path through rough grassland.The entrance lead down almost a foot before levelling out into the tunnel system.

Droppings Description : 

Droppings are around 0.8cm in length, stubby with rounded ends and round cross section.Pale when fresh, darkening with age.Droppings are deposited in prominent places such as branches, and at feeding sites.
