Gang-gang Cockatoo, Colonists of New South Wales. 
Tue only information I can give respecting this fine species is that it is a native of the forests bordering the 
south coast of Australia, some of the larger islands in Bass’s Straits, and the northern parts of Van 
Diemen’s Land, and that it frequents the most lofty trees and feeds on the seeds of the various Eucalypti. 
A few instances have occurred of its being brought to England alive, where it has borne captivity quite 
as well as the other members of the great family to which it belongs; thus affording sufficient evidence 
that the Black Cockatoos (Calyptorhynchi) would thrive equally well were the experiment made, the form 
and habits of the two birds being very similar. 
The paucity of the account here given will I trust be a sufficient hint to those who may be favourably 
situated for observing the habits of this species, that by transmitting their observations either to myself or 
to any scientific journal, they would be promoting the cause of science, and adding to the stock of human 
knowledge. 
The sexes are readily distinguished by the marked difference in their plumage; both are crested, but 
the crest of the male is a rich scarlet, while that of the female is grey, 
The male has the forehead, crest and cheeks fine scarlet, the remainder of the plumage dark slate-grey ; 
all the feathers, with the exception of the primaries, secondaries and tail, narrowly margined with greyish 
white—decided and distinct on the upper, but much fainter on the under surface ; irides blackish brown ; 
bill light horn-colour ; feet mealy black. 
The general plumage of the female is dark slate-colour, the feathers of the back of the neck and back 
slightly margined with pale grey, the remainder of the upper surface crossed with irregular bars of greyish 
white; the wings have also a sulphurous hue, as if powdered with sulphur; the feathers of the under sur- 
face are margined with sulphur-yellow and dull red, changing into dull yellow on the under tail-coverts. 
The Plate represents a male and a female of the natural size.
