Description: Adult Male—Whole head, neck, back, rump, tail, 
breast, wing coverts, under tail coverts and innermost flanks black. 
On the head there is a certain amount of green gloss on the sides, and 
the crest and nape have purple reflections ; the back, scapulars and 
more or less of the wing coverts have a very fine powdering of white, 
so fine as to often require careful looking for before being found, and 
never enough to have any influence on the prevailing tint; primaries 
dark brown, the inner web of the first whitish at the base, fading into 
brown elsewhere, the white on each quill increasing in extent until in 
the innermost only the terminal half inch is dark. In all the quills the 
definition between white and brown is gradual, not abrupt, the two 
colours gradually blending ; outer secondaries white with black tips, 
inner secondaries black glossed with green. Abdomen white sharply 
defined from the breast but more or less mottled near the black flanks. 
Irides bright yellow ; bill deep slate, tipped black ; legs dull lead- 
colour.
