If we regard the White Cockatoo of Van Diemen’s Land, that of the continent of Australia, and that of 
New Guinea as mere varieties of each other, this species has a more extensive range than most other 
birds. It is an inhabitant of all the Australian colonies, both on the southern and northern coasts, hut 
has not yet been observed on the western. 
On a close examination of specimens from the three countries above mentioned, a decided difference is 
observable in the structure of the bill, but of too trivial a character, in my opinion, to warrant their being 
considered as distinct ; in fact, it would seem to he merely a modification of the organ for the peculiar 
kind of food afforded by the respective countries. The Van Diemen’s Land bird is the largest in every 
respect, and has the hill, particularly the upper mandible, less abruptly curved, exhibiting a tendency to the 
form of that organ in the genus Liemetis : the hill of the New Guinea bird is much rounder, and is, in fact, 
fitted to perform a totally different office from that of the White Cockatoo of Van Diemen’s Land, which 
I have ascertained, by dissection, subsists principally on the small bulbs of the terrestrial OrchidacecB, 
for procuring which its lengthened upper mandible is admirably adapted ; while it is more than probable 
that no food of this kind is to be obtained by the New Guinea bird, the structure of whose bill in- 
dicates that hard seeds, nuts, &c. constitute the principal part of its diet. The crops and stomachs 
of those killed in Van Diemen’s Land were very muscular, and contained seeds, grain, native bread (a 
species of fungus), small tuberous and bulbous roots, and, in most instances, large stones. 
As may be readily imagined, this bird is not upon favourable terms with the agrieulturist, upon whose 
fields of newly-sown grain and ripening maize it commits the greatest devastation ; it is eonsequently 
hunted and shot down wherever it is found, a circumstance which tends much to lessen its numbers ; 
it is still, however, very numerous, moving about in flocks varying from a hundred to a thousand in number, 
and evinces a decided preference to the open plains and cleared lands, rather than to the dense brushes 
near the coast. Except when feeding, or reposing on the trees after a repast, the presence of a flock, 
if not seen, is certain to be indicated by their horrid screaming notes, the discordance of which may 
be slightly conceived by those who have heard the peculiarly loud, piercing, grating scream of the bird 
in captivity, always remembering the immense increase of the din oecasioned by the large number of 
birds emitting their disagreeable notes at the same moment ; still I ever considered this annoyance amply 
compensated for by their sprightly actions and the life their snowy forms imparted to the dense and never- 
varying green of the Australian forest ; a feeling participated in by Sir Thomas Mitchell, who says that 
“ amidst the umbrageous foliage, forming dense masses of shade, the white Cockatoos sported like spirits 
of light.” 
The situations chosen by this bird for the purpose of nidification vary with the nature of the locality it 
inhabits ; the eggs are usually deposited in the holes of trees, but they are also placed in fissures in the 
rocks wherever they may present a convenient site ; the crevices of the white cliffs bordering the Murray, 
in South Australia, are annually resorted to for this purpose by thousands of this bird, and are said to be 
completely honeycombed by them. The eggs are two in number, of a pure white, rather pointed at the 
smaller end, one inch and seven lines long by one inch two and a half lines broad. 
All the plumage white, with the exeeption of the elongated occipital crest, which is deep sulphur-yellow, 
and the ear-coverts, centre of the under surface of the wing, and the basal portion of the inner webs of the 
tail-feathers, which are pale sulphur-yellow; irides and bill black ; orbits white ; feet greyish brown. 
The figures are somewhat smaller than the natural size.
