THE VOLES
These little mammals are all members of a family of rodents which are set apart by their stocky, clumsy build, small ears, blunt heads, and certain skeletal differences. They have a decided preference for the colder regions of the globe and are generally a populous group in the world of rodents, the most numerous and widely distributed of which are the meadow voles. They are merely listed here to show the variety that have been found in the Park and to give an indication of their relative abundance. The final identification of some of them is possible only on close examination and measurement. For identifying characters, consult the reference mentioned in the preface.
