The black-legged parrot (Pionites xanthomerius ), also known as the western white-bellied parrot, is a parrot species of the genus Pionites in the family Psittacidae. The species is native to eastern Peru, western Brazil, and northern Bolivia, although it may have been extirpated from Santa Cruz as a result of habitat destruction. Despite its population being in decline, the IUCN classifies it as Least Concern, citing its large range and relatively slow decline. The three species Pionites leucogaster (green-thighed parrot), Pionites xanthomerius (black-legged parrot), and Pionites xanthurus (yellow-tailed parrot) were previously lumped as Pionites leucogaster. The IOC World Bird List still considers it to be a subspecies of the green-thighed parrot (Pionites leucogaster xanthomerius ).
