Range DescriptionWidespread in plains and mountains on both sides of the Andes, from northern Chile (17°S) down to Tierra del Fuego (54°S). In Argentina, they occur in the western and southern arid and semi-arid regions of the country, from ca. 23°S (Jujuy and Salta) to Tierra del Fuego, and from the eastern foothills of the Andes mountain range to meridian 66°W, reaching the Atlantic coast (ca. 63°W) south from Río Negro. Present in the following provinces: Jujuy (Jayat et al. 1999), Salta (Mares et al. 1996), Tucumán, Catamarca, Santiago del Estero, La Rioja, San Juan, Mendoza, west of San Luis, Neuquén, west of La Pampa, Río Negro, Chubut, Santa Cruz and Tierra del Fuego (Osgood 1943; Olrog and Lucero 1981).
Widespread in Chile from the I Administrative Region (Atacama Province) in the north, south to the Strait of Magellan (XII Administrative Region, Magallanes Province) and Tierra del Fuego (Medel and Jaksic 1988; Marquet et al. 1993), and from the western foothills of the Andes mountain range to the Pacific coast (71–73°W). They were introduced to Tierra del Fuego in 1951 in an attempt to control rabbit (Oryctolagus cuniculus) infestation (Jaksic and Yáñez 1983).
Other populations have been reported to exist in some of the southern Atlantic islands, including Malvinas/Falkland (Olrog and Lucero 1981), but this requires confirmation. Their presence in Peru is uncertain.
