The deer mouse’s 564 North Carolina records are a mountain map. Nearly all of the leading counties sit in the far west, Macon, Jackson, Yancey, Transylvania, and Haywood among them, and the top places read the same way: Great Smoky Mountains National Park, Pisgah and Nantahala national forests, the Blue Ridge Parkway, and the Appalachian National Scenic Trail. In this state the deer mouse is a creature of the high country, while its close relative the white-footed mouse fills the Piedmont and Coastal Plain.
A nocturnal seed eater
Deer mice work the night, gathering seeds, nuts, berries, and insects and caching extra food in their nests, which they tuck into hollow logs, stumps, rock crevices, and abandoned burrows. Large eyes and ears and strong climbing ability suit them to the dark forest floor, and in the cool mountain woods they stay active through the year rather than hibernating.
Spring and late-summer highs
Reports crest in April and May and again in August. Mountain deer mice breed from spring into fall, raising several litters, so those highs track renewed spring activity, breeding, and the late-summer dispersal of young mice into new ground. Winter counts stay low but never vanish, fitting an animal that forages in every month.
Status in North Carolina
NatureServe ranks the deer mouse S5, Secure, in North Carolina, and the species is native to the state. USGS NAS does not list it as nonindigenous here.
