Microtus pennsylvanicus, commonly known as the meadow vole, is a small rodent found primarily in North America. It typically inhabits grasslands, meadows, and wetlands, where it builds extensive burrow systems. This species has a stocky body, short legs, and a short tail, with fur that is usually brown or gray. Meadow voles are herbivorous, feeding on grasses, seeds, and roots. They play a significant role in their ecosystem by serving as prey for various predators, including hawks, owls, and foxes. Their population can fluctuate significantly, often influenced by environmental conditions and food availability.
