Round and slender, ranging from 2 3/4 to 4 inches long in body length with a pointed nose and large, black, beady eyes. Ears are large with little fur covering them. Body is bicolored with a light brownish-reddish top and white underbelly and feet. Tail is short, distinctly bicolored (dark on top and light on bottom), and covered with short, fine hairs and can be two to five inches in length if present. 

Nests within hollow logs, tree holes, under piles of stones or logs. Most commonly associated with prairies or other rural, bushy or wooded areas. Avoids humans if indoors, preferring attics, basements or crawl spaces. Next to the house mouse, the deer mouse is the most common small mammal in North America with a wide distribution. 

Omnivorous, but prefers seeds, nuts, small fruits and berries, insects, centipedes, and the subterranean fungus Endogone.
