C. brachyurus is an omnivorous species. They feed off of birds and rodents, and sometimes get in to trouble with farmers for eating domestic chickens. Maned Wolves also have a fondness for lobeira, a tomato-like fruit. They are nocturnal and do all of their hunting at night.
Maned Wolves are dwindling in number due to habitat loss and hunting. Many peoples believe that the Wolves have mystical properties, and they are killed for their magical body parts. Maned Wolves are listed as near threatened, with around 20,000 remaining.
