MH

Identification: Small eyes and very small ears with a blunt nose. The grey brown fur on the head and back is not really contrasted with its grey flanks and underside. The tail is less than half the length of the body. The only confusion species is bank vole. General: A native species, locally common in many rural habitats but much more particular about its habitat than bank voles. They like open grassland, mountain heath, dunes and plantations - grass must be high enough to provide cover from predators. They live mainly in a network of runways in vegetation and underground burrows, are very territorial and will defend their runway/burrow systems. Young are born blind and hairless between April and October - sometimes later in mild conditions and independent in about 3 weeks. They are almost entirely herbivorous feeding on grass and plants. They Burrows / runs have many native predators both mammalian and avian and are largely crepuscular (but can be active both day and night). Distribution - UK: There are thought to be in the region of 75 million field voles distributed widely but patchily throughout the UK in all parts except for Northern Ireland and some Scottish islands. The population is stable.
