Field Vole

The field vole or short-tailed vole, Microtus agrestis, is a grey-brown vole, around 110mm in length, with only a short tail. They are one of the most common mammals in Europe, ranging from the Atlantic coast to Lake Baikal. They are found in moist grassy habitats, such as woodland, marsh, or river banks. Although they dig burrows, they usually build nests above ground. As an important food source for owls and some other predators, their population peaks and troughs in a four-year cycle.
