Diet
The culpeo is an opportunistic predator that will take any variety of prey. It mainly feeds on rodents and
lagomorphs (especially the introduced
European rabbit and
European hare); however, it occasionally feeds on domestic livestock and young
guanacos. Culpeos are considered beneficial because they are significant predators of the rabbits introduced in 1915; such introduced rabbit populations are believed to have allowed culpeos to spread from the Andean foothills across the Patagonian plain. They sometimes take young lambs up to 1 week old. In limited studies, the larger culpeo appears to dominate potential competitors, including

Taxonomy
The taxonomy of the culpeo has been the topic of debate due to their high phenetic variability and the scarcity of research, among other things. Over the past three decades, they have been placed variably in the genera ''Dusicyon
''Dusicyon'' is an extinct genus of South American canids. The type species is ''Dusicyon australis'', the Falkland Islands wolf. In 1914, Oldfield Thomas established this genus, in which he included the culpeo and other South American foxes. ...
