Microtus ochrogaster, M. pinetorum, and M. pennsylvanicus
There are three species of voles in Missouri: prairie, meadow, and woodland voles. These mouselike rodents have rounded, blunt snouts, chisel-shaped front teeth, and short tails.
The North American deermouse is found statewide, usually in open habitats like fields and grasslands. It, and our other three species of Peromyscus mice, look a lot alike.
About Mammals in Missouri
More than 70 species of wild mammals live in Missouri: opossums; shrews and moles; bats; rabbits; woodchuck, squirrels, beaver, mice, voles, and other rodents; coyote, foxes, bear, raccoon, weasels, otter, mink, skunks, bobcat, and other carnivores; deer and elk; and more. Most of us recognize mammals easily — they have fur, are warm-blooded, nurse their young, and breathe air.
