The Nestor Cockatoos are not only striking in their appearance, but lead a somewhat remarkable life; they are confined to a very limited district, only inhabiting New Zealand and the neighbouring islands. The bird we have just described is only found on Philip's Island, the circumference of which does not exceed five miles; and Gould informs us that people living for many years on Norfolk Island, at about four or five miles distance, have never seen it. The extremely limited extent of the habitat of this species is very unpromising as regards its preservation, and it will doubtless soon share the fate of the DRONTE; since the cultivation of the island, it has been periodically hunted, and its days are numbered; probably it is already extinct, as we have seen nothing of it for several years. The rocky parts of the island, partially covered with trees, form, or rather _did_ form, its favourite resort; here it passes its time, principally upon the ground, seeking for roots, which it digs up with its beak, at least, so we imagine, as the bill is often found covered with earth, and, indeed, we can well believe that so remarkable an instrument may be employed for this purpose. According to some naturalists it sucks nectar, although its tongue does not, like that of the Lory, end in a tuft, but has only a nail-like horny plate at the tip, closely resembling the nail upon a human finger. The hard nuts that other parrots enjoy are avoided by the Nestor, whose beak is not strong enough to break the shell. Gould saw one of these birds in the possession of Major Andrews, in Sydney; it was a cheerful, lively companion, and seemed fully inclined to attract the attention of strangers. Its habits differed considerably from those of other parrots, and its owner did not keep it in a cage, but allowed it to fly about the entrance-hall. We are told of another tame Nestor that it had a great fondness for green food, and would pick the leaves of lettuce and other juicy plants. The voice of this bird has a harsh, quavering, snarling sound, much reminding us of the barking of a dog. As regards its propagation, we only know that it is said to lay four eggs in some hole in a tree. THE EAGLE COCKATOO.
