The South American pileated parrot (Pionopsitta pileata), also known as the red-capped parrot (leading to easy confusion with the Australian Purpureicephalus spurius), is a medium-small species of parrot with a total length of about 22 cm (8.7 in). It is found in or near the Atlantic Forest in south-eastern Brazil, far north-eastern Argentina and eastern Paraguay. A local name in Paraguayan Guaraní is cúiu cúiu.
