Field Guide

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

The thirteen-lined ground squirrel has 13 alternating brown and whitish lines (some may be broken into spots) along its back and sides, creating rows of whitish spots within dark lines. It stands upright to survey its surroundings and dives into its burrow when it senses danger.

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.

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!
