In very old birds the black bars on the sides of the breast 
tend to disappear altogether, leaving the undersurface almost 
entirely uniform, the under tail coverts pale buff, and with 
practically no stain of chestnut on the basal part of the outer 
tail feathers. The forehead and crown is pale hoary buff, un- 
barred. 
Younger birds have the sides of the breast much barred 
and the base of the throat and sides of the head barred black 
and buff, the middle of the abdomen is more buffy and the 
under tail coverts deeper buff. The bases of the outer tail 
feathers are largely chestnut and the top of the head is barred 
transversely with chestnut and black. 
Still younger males resemble these, but the undersurface 
is still more barred, some of the feathers being rich chestnut, 
as are also the under tail coverts. There is no grey whatever 
on the inferior aspect of the tail, which is barred chestnut 
and black and there is little amethystine gloss on the hind 
neck. 
Adult females have the undersurface, including the under 
tail coverts with regular transverse bars of black and buff; the 
upper surface is also regularly barred with a strong greenish 
gloss on the hind neck. 
Young females lack the greenish gloss, have the under 
tail coverts uniform chestnut as in the young male and are 
much suffused with rufous chestnut beneath. 
In very old females, the tail tends to become like that of 
the adult male and the bars on the crown become obsolete, 
leaving the crown uniform dark greyish, paler at the nostrils 
but never apparently pale hoary buff as in the fully adult 
male. 
We have compared the above series with an adult male and 
two adult females from the mountains of the Malay Peninsula 
and can detect no material differences; in all the cross bars on 
the tail are more or less broken at the shaft. The ground colour 
above is perhaps rather darker in the peninsular specimens 
and the cross barring on the mantle more maroon and less 
chestnut in colour and decidedly narrower, but these differ- 
ences are probably only individual.
