Argentine Grey Fox

The chilla, grey zorro or South American Grey Fox (Pseudalopex griseus), also known as the Patagonian Fox, is a species of zorro (false foxes).

Range and Habitat

The South American grey fox is found in the southern cone of South America, particularly in Argentina and Chile. Its range comprises a stripe, both sides of the Andes Mountain Range. In Argentina, this species inhabits the western semiarid region of the country, from the Andean spurs to meridian. South from the Río Grande River, the distribution of the grey fox widens reaching the Atlantic coast. In Chile “chillas” are present throughout the country. Their presence in Peru has been mentioned. To date, however, there has been no confirmation of it. The South American grey fox occurs in a variety of habitats. They inhabit from the warm, dry scrublands of the Argentinean Monte and the cold, dry Patagonian steppe to the forest of southernmost Chile.
