Instead of the large bare space which occupies the whole of the face and cheeks of the large Mac-caws, the nakedness in this bird is confined to the orbits, and a space between the eyes and the bill, continuous with the cere which covers the base of the latter. The bill itself, though equally massive and powerful in comparison to the bulk of the bird, is differently shaped, the tip being suddenly drawn to a very sharp and delicate point. It is a native of Brazil, Paraguay, and other parts of South America, and occurs in great numbers upon the banks of the Amazons. Its food consists of the kernels of the harder fruits, for obtaining which, its powerful bill is admirably adapted. In disposition it is wild, and not easily tamed; and, though noisy and vociferous in its native woods, appears to possess little or no capability of imitating the sounds of the human voice. Its length is above 12 inches, of which the tail measures about six. The upper mandible is yellowish-white, the under deep greenish grey. The cere, orbits, and denuded space, yellow; the forehead and eyebrows are azure-blue, the feathers rather rigid, and of open texture; the crown of the head, the neck, and the whole of the upper and under parts of the body are of a fine lively grass-green. The elbow and ridge of the wings, as well as part of the inferior wing-coverts, are vermilion-red. The wings and tail are green above, the under surface of a dusky wax-yellow. The feet are blackish-grey, the claws black, strong, and falcate.
