The pichi (Zaedyus pichiy), dwarf armadillo or pygmy armadillo is an armadillo native to Argentina. It is the only living member of the genus Zaedyus, and the only armadillo to hibernate. Pichis are relatively small armadillos, measuring approximately 11 in long, with a tail of about 4.3 in. Adults weigh from 25 to 53 oz. Pichis are found from central and southern Argentina (Patagonia), west to the Andean grasslands of Chile, and south to the Strait of Magellan. Within this region, it most commonly inhabits arid or semiarid steppe grasslands, but may be found in other environments if they have sandy soils suitable for burrowing.
Pichis are omnivorous, with the largest part of their diet consisting of invertebrates such as beetles, ants, and scorpions, though they will also eat small mammals or lizards, as well as plant material and fungi. Despite living in arid environments, they are not thought to drink water in the wild. Common predators include crowned eagles, buzzard-eagles, foxes, and cougars. Pichis are the only armadillos known to hibernate. Like many hibernating animals, they build up considerable fat reserves before entering their winter burrows, where they remain from May to August.
The IUCN has rated the conservation status of Z. pichiy as near-threatened. It is hunted for subsistence and sport, despite being protected. The armadillo is eaten and used in local handicrafts. Cattle ranching poses a threat to its habitat. Some populations have also been impacted by an unknown disease.
