The Panamint Chipmunk (Neotamias panamintinus) inhabits pinyon pine-juniper woodland in the Great Basin region of California and Nevada.
Description
From Best et al. (1994): "The Panamint chipmunk is medium-sized (Jameson and Peeters, 1988), and is characterized in summer pelage by bright tawny colors and a conspicuous gray rump, and in winter pelage by duller colors and even more gray on the rump (Howell, 1929). The color is pale buff, with black areas restricted. The crown of the head is pale gray. The dark facial stripes are reduced, the superciliary and ocular stripes are narrow and well defined, and the submalar stripe usually is faintly indicated. The cheeks and pale facial stripes are pale gray, nearly white, and not suffused with ochraceous coloration. The dark dorsal stripes, except the median stripe, usually are brown rather than black; the outermost stripes scarcely are distinguishable from the color of the sides. The inner and outer pale dorsal stripes are about equal in width, and usually are faintly washed with ochraceous coloration. The underside of the tail is paler than the sides in summer pelage, with the subterminal black area extending ca. 12 mm anteroposteriorly. In winter pelage, the fur is long arid silky, colors are yellowish, and markings are inconspicuous (Johnson, 1943)."
