The plumages of the youag birds which are in various stages 
are very interesting. In the earliest stage represented the plumage 
is dull brown everywhere except on the throat, which is white. 
The feathers of the head, neck, upper back, breast and flanks have 
pale fulvous central stripes. The duker che2ks and ear-coverts are 
already distinguishable, and the quills are brown without any 
indication of the white band. 
In a somewhat older bird the breast feathers are fulvous 
with fine black margins only, the crown aad forehead are nearly 
black with broad pale striz; the nape is a golden fulvous or buff; 
the upper back brown with pale centres to the feathers, and the 
lower back and wing-coverts brown with each feather edged darker. 
The quills are the same as in the adult bird. 
From this stage the bird apparently moults into the full 
male and female adult plumage.

The femvle from Hup Bon is in juvenile plumage. The 
two males both have the abdomen an] vent a very chestnut red 
rather than vinaceous red as it is on the breast. This miy be due 
to the fact that these two specimens have not vet acquired their 
full colouration.
