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 65 to 110 mm (2.6 to 4.3 in) of length and weigh about 6 to 14 g (0.21 to 0.49 oz). Head and body length of 50 to 90 mm (2.0 to 3.5 in) and hind foot length of 14 to 18 mm (0.55 to 0.71 in).[1] The skin color is light brown or dark-brown to brownish yellow on the upper side and paler on the underside, but generally brownish.[1]


There are 13 species listed in Mammal Species of the World (2005).[2]
