Strix chacoensis
A medium-sized owl endemic to the Gran Chaco of South America, with a round tuftless head and a pale greyish-white facial disc marked by concentric dark lines. The IUCN assesses it as Near Threatened. It is seldom kept in captivity.
The Chaco owl (Strix chacoensis) is a monotypic medium-sized owl of the Gran Chaco in southern South America. The head is round and tuftless, and the adult's facial disc is pale greyish white with concentric dark lines. The upperparts are dusky brownish black with narrow white and buff barring, the underparts off-white barred dark brown, and the tail dark greyish brown with narrow pale bars. Originally described as a species, it was soon demoted to a subspecies of the rufous-legged owl, but a 1995 study of morphology and voice showed the original treatment to be correct; later work suggests it is closer to the rusty-barred owl than to the rufous-legged. It occupies the low-rainfall Gran Chaco across hilly, rolling and flat terrain in both dense and semi-open forest, recorded in Argentina between 500 and 1,300 m. Mainly nocturnal, it is vocally active at dawn and dusk and hunts by dropping from a perch. Its breeding biology is poorly known; it probably nests in tree cavities or holes in the ground, and captive females lay two or three eggs.

Frozen mice, day-old chicks and quail; in the wild small mammals, birds, reptiles and invertebrates
As a bird thought to nest in tree cavities or ground holes, it suits an aviary with a nest box and perches at several heights. Coming from dry forest, it needs the floor kept dry.
Seen alone in the wild, with no group sociability. Mainly nocturnal but most active at dawn and dusk.
The male sings a distinctive frog-like crococro craorr-craorr with emphasis on the first craorr, and the female's song is similar but higher pitched. Both call most at dawn and dusk.
The IUCN assesses it as Near Threatened. It is listed on CITES Appendix II, so import requires an export permit. Little is known about its breeding and the species is seldom kept, so seek advice from experienced keepers before acquiring one.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
