Mexican ground squirrel

The Mexican ground squirrel is a small to medium-sized rodent with nine rows of white spots on its back.^[2] It ranges in body length from 32.2 centimetres (12.7 in) to 38.0 centimetres (15.0 in).^[2]

The Mexican ground squirrel is found in central Mexico from Jalisco to Puebla.^[2] It typically occupies grasslands and brush habitats where it is often associated with mesquite and nopal cactus.^[2] It may also be found up to 3,200 metres (10,500 ft).^[4]

The Mexican ground squirrel was historically considered to have two disjunct subspecies; with one occurring in central Mexico (Spermophilus mexicanus mexicanus) and one occurring in the southwestern United States and northern Mexico (Spermophilus mexicanus parvidens).^[2] In 2009, the northern population was reclassified as a distinct species, the Rio Grande ground squirrel, due to its smaller body size and geographic isolation.^[3]
