Red-shouldered macaw

The red-shouldered macaw (Diopsittaca nobilis) is a small green South American parrot, a member of a large group of Neotropical parrots called macaws. The species is named for the red coverts on its wings. It is the smallest macaw, being 30–35 cm (12–14 in) in length - similar in size to the Aratinga parakeets. It is native to the tropical lowlands, savannah, and swamplands of Brazil, the Guianas, Bolivia, Venezuela, and far south-eastern Peru. It has two distinct subspecies, the noble macaw and the Hahn's macaw, and a possible poorly distinct third subspecies that has longer wings, but is otherwise similar to the noble macaw. The Hahn's subspecies is named for German zoologist Carl-Wilhelm Hahn, who in 1834 began compiling Ornithologischer Atlas oder naturgetreue Abbildung und Beschreibung der aussereuropäischen Vögel (Engl: Ornithological Atlas or natural depiction and description of birds from outside Europe).

Red-shouldered macaws are frequently bred in captivity for the pet trade, where they are sometimes described as mini-macaws.

Though wild populations of red-shouldered macaws have declined locally due to habitat loss, they are listed as Least Concern by IUCN. They are listed on Appendix II of CITES, trade restricted.
