The Golden Mouse is the most arboreal mouse in the southeastern United States. Its tail is semi-prehensile and is used for both balance and grasping. The Golden Mouse builds globular nests in and under fallen logs for winter use. In warm months, it nests in trees, vines, or clumps of Spanish moss, sometimes as high as 9.1 m (30 ft). Its arboreal nest is used as both a nursery and a shelter. The nest is constructed of an outer layer of leaves with an inner lining of grasses and soft shredded bark. This species also builds loosely constructed platforms that are used for feeding and resting. The Golden Mouse is both nocturnal and crepuscular, foraging for food through the evening and night hours. It eats a variety of seeds, nuts, berries, and insects.
The Golden Mouse is found throughout the southeastern quarter of the United States, from Virginia to Missouri south to eastern Texas to Georgia and the northern half of Florida.
The Golden Mouse is common in deciduous hardwood and coniferous pine forests.
The White-footed Mouse is similar in size and basic fur pattern, but its upper parts are reddish-brown rather than the striking golden color of the Golden Mouse.
