Deer mice are small rodents that range from 6 to 8 inches long including their tail. They have large round ears, bulging eyes, and can live up to 8 years. Deer mice are active year-round, do not hibernate, and have 4 litters per year containing 2-7 babies each. They eat various seeds, fruits, insects, and fungi. As a common species, deer mice are an important food source for many predators like coyotes, owls, and snakes. They typically make nests in tree stumps, under logs, or abandoned squirrel nests using materials like moss and leaves.
