whilst the Nose Cockatoo on the contrary pronounces the two first syllables hurriedly, and lays a strong emphasis on the last. The facility with which this parrot can move its beak in any direction is very remarkable, and no other species that we are acquainted with has such suppleness and command of the joints of its jaws. The beak of the Nose Cockatoo is, indeed, the most extraordinary pair of pincers that ever was constructed. In justice to this bird, we must add to the foregoing remarks that it may occasionally be made very tame, and not only learns to speak, but is able to apply its language very intelligently. There is one in the Zoological Gardens at Antwerp that is an universal favourite with the visitors, with whom it converses freely, greeting its acquaintances as soon as they appear, without the slightest ill-humour or sullenness. THE NESTOR COCKATOO. The NESTOR COCKATOO (_Nestor productus_) represents a very remarkable tribe of parrots, recognisable by their extraordinarily elongated beak and sickle-shaped upper mandible, which projects far beyond the lower. The tail is of middle size, the points of the tail-feathers being in some places denuded of their web, and the wings, when closed, reach nearly to the middle of the tail. The tarsus is decidedly higher, and the plumage harsher and more imbricated than in other Cockatoos. In our specimen it is much variegated, the upper part of the body is brown, the head and back of the neck mottled with grey, each of the feathers covering these parts being bordered with a darker shade. The under part of the body and tail-covers are of a deep red; the breast, throat, and cheeks, are yellow, the latter having a reddish tint; the tail-feathers are orange at the root, and striped with brown: the inner web of the quills is dark red and brown; the bare place round the eyes, the legs, and the cere, are of an olive brown; the beak is brown; and the eye a very dark brown. Both sexes are similarly coloured, but the young are of a dark olive brown on the breast, instead of being adorned with the red and gold that decks their parents.
