Otospermophilus variegatus is a medium-sized squirrel, with a mottled, grayish-brown coat and a well-marked, lightcolored ring around each eye. This species has a long, hairy tail ( Oaks et al. 1987; Phuong et al. 2014).
Distribution. Central, southwestern USA, through most of northern and central Mexico to the TMVB ( Oaks et al. 1987). Recorded habitats in Chihuahua are quebradas, si- erras, valleys, and arid lands.
Remarks. Ten sciurids have been recorded in Chihuahua ( López-González and García-Mendoza 2012). Of these, six species are present in the Sierra Madre Occidental. Otospermophilus variegatus is frequently seen in rocky habitats.

Identification. This is the only species of the genus in Mexico. It is a medium-sized cat, with a short tail and red or grayish dorsal pelage. The underparts are white with black spots. Ears have pointed tufts, and the hair on sides of head are long ( Larivière and Walton 1997; Loveless et al. 2016).
Distribution. Southern Canada, USA, through most of northern and central Mexico to the TMVB ( Larivière and Walton 1997). Recorded habitats in Chihuahua are quebradas, sierras, and valleys.
Remarks. This species is a common felid inhabiting most of the state ( López-González and García-Mendoza 2012), even in urban and semi-urban areas. However, it is rarely observed in the sierras because of its habits.
