The maned wolf (Chrysocyon brachyurus), is the largest species of canid of South America. In Argentina, information about this species is scarce. We described the feeding habits collecting fecal samples inside the Natural Reserve Rincón de Santa María (RSM) (29° 50’ S, 58° 35’ W), Corrientes province, Argentina. The diet was composed of fruit (Psidium sp.) (50%) and animal prey: armadillos (11.1%), birds (8.4%), fishes (5.6%), reptiles (2.8%) and crustaceans (2.8%). Despite a low dietary composition, our results showcase the dietary flexibility of the maned wolf in an area dominated by an anthropized landscape.
