Field Vole, Microtus agrestis
The field vole (Microtus agrestis) is native to Europe, inhabiting a large range that includes Poland, France, Germany, and Belgium, among many other areas. It is not found in Ireland or in Iceland. It prefers a habitat within moist grasslands, like marshes and woodlands and along riverbanks. The population density of the field vole will fluctuate throughout a four-year period.
The field vole will dig burrows underground, but it most commonly builds nests on the surface. It reaches an average body length of 4.3 inches and bares a short tail. It is a vital food source to owls, among other predators. The diet of this vole consists mainly of plant materials like bark and grass, but it is known to eat larvae as well. The field vole appears on the IUCN Red List with a conservation status of “Least Concern”.
