Field Guide

When you see the black mask and striped tail of this medium-sized mammal, you know you’ve spotted a raccoon. These nocturnal omnivores are clever and adaptive.

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 common muskrat is one of the most abundant commercial furbearers in Missouri. This semiaquatic rodent has benefited from the construction of thousands of farm ponds throughout the state.

The nutria is a large aquatic rodent native to South America. They were brought to the United States for the fur market. In Missouri, nutria are sometimes trapped in the southeastern part of the state.

The American beaver is a semiaquatic rodent distinguished by its large size, webbed hind feet, and large, horizontally flattened tail covered with leathery scales.

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

The American mink is a semiaquatic predator and a member of the weasel family. It is famous for its durable, soft, valuable fur.

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.

The North American river otter was once nearly eliminated in Missouri, but thanks to restoration efforts, these powerful swimmers are once again found throughout most of the state.
