The eastern meadow vole is a small-to-medium sized mouse. It has a long tail and short ears. The eastern meadow vole resembles the common house mouse, but it is slightly smaller and has a more pointed snout. Eastern meadow voles are mostly black, but they may also be brown or reddish-brown. They have white spots on their chest and an inverted “V” pattern on their back. Eastern meadow voles live in colonies of up to 30 individuals underground, but they also forage largely on the surface.
