Western Deer Mouse
Peromyscus maniculatusAlso known as North American Deer Mouse, Deermouse
Western deer mice are agile, nocturnal rodents recognized by their striking two-toned coat, featuring a dark fawn-colored back and a clean white belly and feet. They navigate diverse landscapes from forests to deserts with ease, using their large eyes and sensitive whiskers to forage for seeds and insects under the cover of darkness. These industrious builders construct cozy nests in tree cavities, rock crevices, or abandoned burrows, playing a vital role as seed dispersers and prey for countless forest predators.
