Adult male:—Head, nape, mantle, inner and lesser wing 
coverts shining black; ear coverts, sides of the face and throat 
dark grey. Primaries and secondaries the bases of all the tail 
feathers and the greater part of the two median pairs, black; 
greater inner wing coverts with their terminal portions scarlet; 
Primaries and secondaries from the fifth primary inwards with 
their outer webs edged with scarlet, increasing progressively 
inwards, the basal half of both webs scarlet orange. Rump 
and upper tail coverts scarlet, under surface except the throat 
and portion of the tail that is not black, scarlet orange, thighs 
mingled black and orange buff or apricot; wing lining edge 
of the wing and axillaries orange. Bill and feet black, iris dark 
hazel. 
Adult female:—Daistribution of colour similar to that of the 
male, the red throughout being replaced by yellow intermediate 
between “Cadmium Yellow” and “Light Cadmium” of 
Ridgeway.. The black of the upper surface more greyish blue 
and less shining than that of the male and the ear coverts of a 
paler grey. Chin and upper throat greyish white. Thighs 
mingled white and brownish black. This is the stage described 
as P. croceus by Ogilvie Grant (Fascic. Malay. loc. cit. p. 97.) 
Immature.—The immature of both sexes are similar to the 
adult female, except that the head and mantle are of a paler 
grey, with much less gloss and the yellow of the rump and 
upper tail coverts has a strong cast of olive, while the bases of 
the feathers are broadly grey, giving an impression of ill-defined 
cross barring. This is the stage figured by Sharpe (Joc. cit.) as 
the adult female of P. wray1. The adult male plumage appears 
to be attained from this stage in part by a moult of the yellow 
feathers and in part at least by a direct colour change, though 
by the majority of authorities on moulting this is roundly 
asserted to be impossible. 
Juvemle.—Younger birds still resemble the immature 
female but have a greenish tinge over the grey of the upper 
parts, the ear coverts even paler grey and the feathers of the 
head and mantle narrowly edged with dirty white.
