Field Guide

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

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.

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.

The eastern gray squirrel and eastern fox squirrel are both very common in Missouri. Their names describe their general coat color: the first is grayish, the other a foxy red.

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!

Very large members of the deer family, elk are brown or tan above with darker underparts, with a thick neck and yellowish-brown rump patch and tail. Elk have been restored in three Ozark counties.

Feral hogs could cost Missouri millions of dollars in agricultural, environmental and property damage. As they root and wallow, they plow the soil to depths of 2–8 inches — sometimes for many acres! And this is just the beginning of the trouble they can cause to humans, livestock, and the environment.

Gray myotises are difficult to distinguish from other mouse-eared bats. A key identifying feature of the gray myotis is that its wing is attached to the ankle and not at the base of the toes. It’s an endangered species.

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.
