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.

One of the largest wild mammals in Missouri, the American black bear is unmistakable with its black fur and powerful bearing.

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.

Mountain lions hadn't been seen in Missouri since 1927 — but in 1994, conclusive physical evidence proved they are reappearing in our state. These animals probably are individuals dispersing from other states, and no breeding population seems to have been reestablished.

The bobcat is a short-tailed wild cat with a distinctive streaked and spotted pattern, a wide face, and pointy ears often with black tufts.

Tri-colored bats, formerly called eastern pipistrelles, are relatively small and look pale yellowish or pale reddish brown. The main hairs are dark gray at the base, broadly banded with yellowish brown, and tipped with dark brown.

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 Indiana myotis, or Indiana bat, summers along streams and rivers in north Missouri, raising its young under the bark of certain trees. It is an endangered species.

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.
