The culpeo is a fox-like canid that is not a true fox and is more closely related to wolves and jackals (Wikipedia, general species account). It is the second-largest native canid in South America after the maned wolf, and it sits in size between a red fox and a coyote. It is grey and reddish, with a white chin, reddish legs and a dark upper back. Its pelt is grizzled, the neck and shoulders are tawny to rufous, and the bushy tail has a black tip (Wikipedia, general species account). Its stripe along the back may be barely visible.
The culpeo is an opportunist that takes whatever prey is available. The larger culpeo appears to dominate potential competitors such as the South American grey fox, Geoffroy's cat, the pampas cat and grisons, and in Patagonia it eats more introduced European hares than the grey fox does, while the grey fox eats more rodents. In colder seasons their diets overlap more, and the culpeo uses its size to exclude the grey fox from areas with richer prey (Wikipedia, general species account). Rabbits introduced in 1915 are believed to have helped it spread from the Andean foothills onto the Patagonian plain. The typical mating period is August to October (Wikipedia, general species account).
Bolivia is included in the species' listed range (GBIF species profile), which otherwise runs from southern Patagonia to Ecuador and Peru. On this guide it is a target species of Eduardo Avaroa Andean Fauna Reserve.
