American water vole

The term "water vole" can refer to a water rat or a specific western North American vole species (Microtus richardsoni). Voles are small, mouselike rodents found in the Northern Hemisphere, characterized by a blunt muzzle, short tail, and small eyes and ears.12

In North America, the American water vole (Microtus richardsoni) inhabits areas near streams and ponds, demonstrating adept swimming and diving skills. Their diet includes roots, rhizomes, and buds of perennial plants.2

Voles inhabit diverse environments, from sea level to high mountains, including prairies, steppes, deserts, meadows, tundra, and various forests. The European water vole (Arvicola amphibius) is the largest Eurasian vole, while the meadow vole (M. pennsylvanicus) is common in North America.2
