Description
From Burt and Best (1994): "Color of the upperparts has a marked reduction of black in the stripes, resulting in a general tone of buffy to pale orangish-red. The sides are buffy and interspersed with gray, the crown is pale gray, and the postauricular patch is large and white (Hoffmeister and Ellis, 1980). The dark medial stripe is chestnut or rufous, with the middle part of the posterior portion black. The inner pair of dark stripes is similar, but lacks the black, or at most it is faintly indicated. The outer pair of dark stripes is nearly obsolete, just a shade darker than the color of the flanks. The inner pair of pale stripes is grayish white, but is not distinct; the outer pair is whiter and clearer. The rump and flanks are grayish, and the sides of the body and upper surfaces of the feet are pale bright-rufous. There is a large white postauricular spot, and the posterior one-half of the ear is whitish. The pale facial stripes are white and the dark ones are rufous, with the lower ones extending under the ear. The top of the head is mixed grayish and rusty, with some black hairs intermixed; ventrally, the head is grayish white. The tail is mixed black and chestnut dorsally, and it is bright chestnut with an indistinct black border ventrally (Barnes, 1922). In winter pelage (November), coloration is similar to summer, but the head and rump are darker. The median dorsal stripe is tawny and shaded with fuscous, and the undersurface of the tail is cinnamon (Howell, 1929)."
