BANKS' RAVEN COCKATOO (_Calyptorhynchus Banksii_) attains the length of a foot and a half. The plumage of the male is black, the only exception being the tail, which is a brilliant black with a greenish sheen. The female is greenish-black upon the head, spotted with yellow on the neck and wings, and striped with light yellow upon the breast. The male has a broad scarlet band extending along the middle of the tail, but not reaching the two middle feathers or the outer edge of the side feathers. The female has broad yellow and reddish-yellow spotted stripes similarly disposed, both upon the outer and the under side of the tail-covers. Banks' Raven Cockatoo belongs to New South Wales, and is principally found in the district between Moreton Bay and Port Philip, though by no means rare in the immediate neighbourhood of Sydney and other large towns. Its flight is heavy; the wings are lax, and seem to move with difficulty; it seldom rises high in the air, but will, nevertheless, sometimes fly for a mile at a stretch; whilst on the wing it utters a loud cry, which is less shrill than the harsh screech of the cockatoo. When on the ground, these birds move with difficulty; upon the tops of trees their motions are less deliberate, but always slow. Most of them are shy and distrustful, owing no doubt to the manifold persecutions from which they suffer, and it is only during feeding-time that they are less upon the watch. They are much attached to their companions, and should one of them be killed or wounded, the hapless individual is seldom deserted by the others, who generally fly about him, uttering a wailing cry, and expose themselves so recklessly to the hunter, that he, knowing how to avail himself of this habit, often succeeds in capturing the whole flock.
