Field Guide

Of the two species of skunks in Missouri, the spotted skunk is smaller, less common, and lesser known. It has been declining drastically in recent years because of habitat loss.

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 Virginia opossum is North America's only native marsupial. Its life history, biology, and habits make this nocturnal mammal worthy of appreciation. What other mammal in our state can hang by its tail, play dead, and carry its young in a pouch?

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.

One of the best-known wild mammals in Missouri, the woodchuck, or groundhog, is a rodent in the squirrel family. They hibernate in burrows from late October to sometime in February.

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 red fox is doglike, with a long, pointed muzzle; large, pointed ears that are usually held erect and forward; moderately long legs; and a long, bushy tail. It occurs statewide but is more common in the northern and western sections of Missouri.

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.
