Microtus ochrogaster, commonly known as the prairie vole, is a small rodent found primarily in the grasslands of North America. They have a stocky body, short legs, and a short tail, typically measuring about 7 to 9 inches in length. Their fur is usually brown or gray, providing camouflage in their natural habitat. Prairie voles are social animals that live in family groups and are known for their monogamous mating behavior. They create extensive burrow systems and are herbivorous, primarily feeding on grasses and seeds. Their populations can fluctuate based on environmental conditions and predation.
