South American gray fox, better known as the chilla.

It is also possible to view culpeos and South American gray foxes.

The South American gray fox breeds in late austral fall, around March.

The South American gray fox is a largely solitary animal that has long been hunted for its pelt.

Where their ranges overlap, the South American gray fox is in competition with the larger culpeo fox.

South American gray foxes were introduced and are having a detrimental impact on birds that nest on the shores, as are feral cats.

The less arid parts of the desert are inhabited by the South American gray fox and the viscacha (a relative of the chinchilla).

The South American gray fox Lycalopex griseus, is the most common species, and is known for its large ears and a highly marketable, russet-fringed pelt.

The South American gray fox is found in the Southern Cone of South America, particularly in Argentina and Chile.

It is possible to see a wide variety of wildlife in the park, including pumas, South American grey foxes, culpeos, lesser grisons, kodkods, pudús, viscachas and coypos.

In limited studies, the larger culpeo appears to dominate potential competitors, including South American gray foxes, Geoffroy's cats, Pampas cats, grisons and various raptorial birds.

The ruddy-headed goose, which is the smallest austral goose inhabiting South America, faces several threats such as predation by the South American gray fox, illegal hunting and habitat degradation.

Predators include the mountain lion Puma concolor, South American gray fox Pseudalopex griseus, culpeo fox Lycalopex culpaeus and pampas cat Leopardus pajeros.

The South American gray fox (Lycalopex griseus), also known as the Patagonian fox, the chilla or the gray zorro, is a species of Lycalopex, the "false" foxes.

The South American gray fox occurs in a variety of habitats, from the warm, arid scrublands of the Argentine uplands and the cold, arid Patagonian steppe to the forests of southernmost Chile.

The South American gray fox was introduced to the Falkland Islands in the late 1920s early 1930s and is still present in quite large numbers on Beaver and Weddell Islands plus several smaller islands.

Wildlife on the island includes gentoo penguins, South American gray foxes (introduced, not to be confused with the Falkland Islands wolf), peregrine falcons, southern and striated caracaras, guanacos, fur seals, and many seabirds.

However subsequent analyses suggest the skull and teeth remains to have been from two wild species: Pseudalopex griseus (South American gray fox) and Canis avus (a small fox or wolf-life canine, particular to South America in the late Pleistocene period).

The activity patterns, home-range use, and habitat utilization of sympatric South American grey fox (Dusicyon griseus) and culpeo fox (Dusicyon culpaeus) in eastern Torres del Paine National Park, Chile, were studied to determine how the two species were distributed.

It was long held that Darwin's fox was a subspecies of the South American gray fox (L. griseus); however, the discovery of a small population of Darwin's fox on the mainland in Nahuelbuta National Park in 1990 and subsequent genetic analysis has clarified the fox's status as a unique species.
