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. The red-shouldered macaw, at 30 cm long and 165 g weight, is the smallest of all the macaws. Like all macaws, it has a long narrow tail and a large head. It has bright green feathers on the body, with dark or slate blue feathers on the head just above the beak. The wings and tail have feathers that are bright green above and olive-green below. The leading edges of the wings, especially on the underside, are red. Their eyes are orange, and the skin around the eyes is white without feathers, just as in the larger macaws. This bare patch of facial skin is smaller in proportion to the head than the one seen in most larger macaws. The Hahn's macaw and noble macaw can be distinguished by the Hahn's having a black upper mandible and the Noble's having a lighter, horn-colored upper mandible. Their natural vocalizations are more akin to screeches than they are to whistles.
