Field Guide

The little brown myotis (little brown bat) is one of our most common bats, but populations are declining. White-nose syndrome has taken a heavy toll in northeastern states. This species is now listed as vulnerable across its range.

There’s no other animal in Missouri that can be mistaken for an armadillo! In the 1950s, they were not considered residents, but now they are regularly found in the southern half of the state.

Skunks are omnivorous mammals notorious for their ability to discharge an obnoxious scent when provoked. The striped skunk is the most commonly encountered skunk in our state.

The gray wolf originally ranged throughout Missouri, but with settlement the species was gradually exterminated. While there is no evidence of a breeding population in the state, wolves are listed as a protected species in Missouri, and they occasionally wander into Missouri from northern states.

The eastern cottontail is a rabbit with a perfect name. Its tail, when raised, has a conspicuously white undersurface, resembling a fluff of cotton.

Long-tailed weasels are small but voracious predators. They are rare in our state but are most common in the south-central and southwestern portions. In summer, they are brown with yellow beneath. In winter their fur is paler or white. The tail has a black tip.

This mouse-sized weasel is found only in Missouri’s northern counties, and abundance varies locally and seasonally, depending on fluctuating rodent numbers — their favorite food.

Chipmunks are sleek, attractive, active ground-dwelling squirrels. They live in tunnels but are generally out during the day, making them one of the few mammals that people can enjoy watching.

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.

Eastern moles are plush-furred, large-handed critters infamous for disfiguring lawns as they tunnel belowground hunting for grubs and cutworms — many of which are also dreaded by landscapers!
