The underside of the wings is yellowish, the tail-tip, crown and cheeks are bluish, and the tail-base and small belly-patch are red.

Relatively little information exists on its reproduction in the wild, but the breeding season in north-eastern Brazil is apparently from December to February.

It has declined in the southern part of its range, and there are no recent records from Misiones Province in Argentina where many were killed by farmers who considered them pests.

Information from Brazil suggests it remains widespread and has even re-colonised areas in its historical range in southern Rio de Janeiro.

It is also an avid chewer and may damage its keeper's property unless provided with wooden destructible objects to occupy its time.
