WESTERN MEADOW VOLE

The western meadow vole (Microtus drummondii) is a species of North American vole found in western North America, the midwestern United States, western Ontario, Canada, and formerly in Mexico. It was previously considered conspecific with the eastern meadow vole (M. pennsylvanicus), but genetic studies indicate that it is a distinct species. It is sometimes called the field mouse or meadow mouse, although these common names can also refer to other species.
