Culpeo

Identification

The culpeo is a canid intermediate in size between a red fox and a coyote, and the second-largest native canid on the South American continent after the maned wolf. Males average 11.4 kg (25 lb), while females typically weigh 8.4 kg (19 lb), though the species ranges from 5 to 13.5 kg (11 to 30 lb). Total length ranges from 94 to 133 cm (37 to 52 in), including a tail of 32 to 44 cm (13 to 17 in).

The culpeo's coat has a grizzled appearance with grey and reddish fur. The neck and shoulders are often tawny to rufous, while the upper back is darker. It displays a white chin, reddish legs, and a stripe on its back that may be barely visible. The bushy tail characteristically has a black tip. Despite its fox-like appearance, the culpeo is not a true fox but more closely related to wolves and jackals, with its resemblance to foxes resulting from convergent evolution.

Range & Habitat

The culpeo's range extends from the southern regions of Patagonia and Tierra del Fuego in the south to Ecuador and Peru in the north, with some populations extending into southern Colombia. It is also found in the Sierras Grandes mountain range in Córdoba, Argentina, and is most common on the western slopes of the Andes.

This adaptable species inhabits a wide variety of habitats across western South America, including broadleaf Nothofagus temperate rainforest, sclerophyllous matorral, deserts, chaparrals, and plateaus such as the Altiplano. They are found in open country and deciduous forests, ranging up to the tree line at 4,800 metres (15,700 ft).

Behaviour & Diet

The culpeo is an opportunistic predator with a varied diet. It mainly feeds on rodents (including common degus) and lagomorphs, particularly the introduced European rabbit and European hare. The species also takes insects, birds, lizards, fruit, and carrion of llamas and vicuñas. Occasionally, culpeos prey on young guanacos and may attack farm animals including sheep, goats, and poultry, particularly lambs up to one week old.

In ecological interactions, larger culpeos dominate potential competitors including South American gray foxes, Geoffroy's cats, pampas cats, grisons, and various raptorial birds. Introduced rabbits, brought to the region in 1915, are believed to have allowed culpeos to spread from the Andean foothills across the Patagonian plain. The mating period typically occurs between August and October, with females giving birth after a 55–60 day gestation to usually between two and five pups.

Best Time & Places to See It

Travellers seeking culpeos should focus on the Andean regions and Patagonian plains of western South America, particularly the western slopes of the Andes where they are most common. The species is found across a vast latitudinal range, making it accessible in multiple countries including Argentina, Chile, Peru, Ecuador, and Colombia. They inhabit both lowland open country and montane habitats up to the tree line.

While the species is not threatened with extinction overall, it has become rare in some regions due to hunting in rural Chile and Argentina, where it is persecuted for attacks on livestock. Patience and early morning or dusk observation are typically required to encounter this elusive predator in its natural habitat.

Photography Tips

Photographing culpeos requires patience and attention to habitat. The species favours open country, matorral, and deciduous forests where they can be spotted during low-light periods at dawn and dusk. The grizzled coat with its mix of grey and reddish tones provides natural camouflage, so look for movement in open grasslands and scrubland edges typical of Andean foothills and Patagonian landscapes.

The culpeo's distinctive features—including the bushy black-tipped tail, white chin, and reddish legs—provide good identification markers and photographic subjects. When photographing, be aware that the species may be wary in areas where it is hunted. Distant, patient observation using telephoto lenses is recommended to capture natural behaviour without disturbing this increasingly rare canid.
