The red-carried macaw (Hahns Macaw), at 30 cm (12 in) long and 165 gm (5.8 oz) weight, is the littlest of the considerable number of macaws. Like all macaws, it has a long limited tail and a substantial head. Hahns Macaw has brilliant green quills on the body, with dull or slate blue plumes on the head simply over the mouth. The wings and tail have quills that are splendid green above and olive-green underneath. The main edges of the wings, particularly on the underside, are red. (These red plumes show up at adolescence.) Their eyes are orange, and the skin around the eyes is white without quills, generally as in the bigger macaws. This exposed patch of facial skin is littler in extent to the head than the one seen in most bigger macaws. The Hahn’s macaw and respectable macaw can be recognized by the Hahn’s having a dark upper mandible and the Noble having a lighter, horn-shaded upper mandible.
