Chaco Owl is a medium-sized owl that is distributed through a 766,000 km2 area of southern South America, from the Chaco region of southern Bolivia (Santa Cruz) south western Paraguay and to Argentina, south to Córdoba and Buenos Aires provinces. This owl inhabits both dense and open forests and shrubs on either hilly, rolling and flat areas. Its diet include small mammals, birds, reptiles, insects, scorpions and centipedes. Chaco Owl is mainly nocturnal and crepuscular, and rests during the day in tree cavities, dense brush, isolated trees or even on the ground. This owl primarily is resident, but some individuals may move seasonally among different habitats. Although considered "scarce", it could be locally common. Although Chaco Owl is not considered to be threatened on the global level, local populations of this species may be vulnerable to habitat changes.
