Uinta chipmunk

The Uinta chipmunk, also called the hidden forest chipmunk (Neotamias umbrinus), is a medium-sized chipmunk that lives in the montane and subalpine forests of the western United States at elevations between about 1,400 and 3,650 metres. Adults measure 20 to 24 centimetres including the tail and average about 67 grams. The summer coat ranges from yellowish brown grey to dark brown, with three dark stripes down the back separated by paler stripes, and the winter coat is duller. It is a solitary, diurnal and highly arboreal animal that defends a territory, dens in burrows, rock crevices or hollow logs, and feeds mainly on conifer seeds and shrub fruit, with some grass, fungi, insects and carrion. A single litter of three to five young is born in spring. Its populations are scattered across separate mountain localities, and seven subspecies are recognised. Phylogenetic studies moved it from the genus Tamias into Neotamias.
