Birch mice (Genus Sicista) are small jumping desert rodents that resemble mice with a long tufted tail and very long hind legs, allowing for remarkable leaps. All variants possess a long tail of 6.5 to 11 cm (2.6 to 4.3 in) of length and weigh about 6 to 14 g (0.21 to 0.49 oz). The head length lies between 5 to 9 cm (2.0 to 3.5 in). The skin color is light brown or dark-brown to brownish yellow on the upper side and paler on the underside, but generally brownish.
