The Culpeo is distributed along the Andes and hilly regions of South America from Nariño Province of Colombia in the north (Jiménez et al. 1995) to Tierra del Fuego in the south (Markham 1971; Redford and Eisenberg 1992). It ranges down to the Pacific shoreline in the desert of northern Chile (Mann 1945, J.E. Jiménez, pers. obs.), south to about Valdivia (Osgood 1943) and then again in Magallanes. On the eastern slopes of the Andes, the culpeo is found in Argentina from Jujuy Province in the North, reaching the Atlantic shoreline from Río Negro and southwards. This extended eastward distribution is relatively recent and was apparently favoured by sheep ranching (Crespo and De Carlo 1963; Novaro 1997a).
