The adult male bird has the beak bluish black ; the 

 irides yellow ; the head and cheeks dark ash colour, the 

 feathers on the top and back of the head considerably 

 elongated, forming a conspicuous crest ; the back, sca- 

 pulars, wing-coverts, rump, and upper tail-coverts, greyish 

 black; most of the wing-feathers, wing and tail coverts, 

 with more or less white at the end ; the tail-feathers gra- 

 duated, the two in the centre brown, the outer feathers 

 darker, but all are tipped with white; throat and chest 

 reddish white ; abdomen, under wing and under tail coverts, 

 pure white ; legs, toes, and claws, bluish black. 



The whole length of a specimen in the Museum of the 

 Zoological Society is fifteen and a half inches, of which 

 the middle tail-feathers alone measure eight inches, the 

 outer tail-feather but four inches and three-quarters ; wing 

 from the anterior bend eight inches ; the fourth primary 

 the longest in the wing. 



Considerable differences are observed in the plumage of 

 this species, depending upon age. Mr. Gould says the 

 plumage of middle age differs from that of the adult in 

 having the head and crest of a much darker colour, and 

 the whole of the upper surface more inclining to reddish 

 brown with slight reflections of green ; the primaries are 

 rufous, tinged with greenish brown towards the points, 

 which are pure white ; the throat and chest are light red- 

 dish brown ; the under surface as in the adult male.
