Neotamias rufus

The Hopi chipmunk (Neotamias rufus) is a small chipmunk found in Colorado, Utah and Arizona in the southwestern United States. It was previously grouped with the Colorado chipmunk (N. quadrivittatus). This species is listed as "Least Concern" on the IUCN Red List as it is common, widespread, and without any major threats. It was last evaluated in 2016. == Description == This species is distinguished by somewhat smaller size and a dorsal pelage that generally lacks significant amounts of black in the stripes, resulting in a more orange red to buff pelage. Measurements are: total length 190–235 mm; length of tail 83–95 mm; length of hindfoot 31–35 mm; length of ear 15–22 mm; weight 52–62 g. Females are slightly larger than males. == Habitat == Hopi chipmunks prefer rocky areas with pinion and juniper pines and feed mostly on nuts, seeds and fruits. Food gathered is stored in cheek pouches and taken elsewhere for consumption or storage. They nest in rock piles or crevices. This is the common chipmunk of much of the canyon and slickrock piñon-juniper country in western Colorado. Population densities appear to be highest in areas with an abundance of broken rock or rubble at the base…
