The young bird (cT) is very interesting with reference to 

 the plumage, inasmuch as the feathers of the bead are black with 

 reddish brown or yellow tips (chiefly the former). The nape is 

 also garnished with black feathers, the tips of which are yellow, 

 of the same colour as the back, and the upper tail-coverts are 

 greenish yellow (in the adults yellow). Some of the feathers of 

 the throat are yellow, others black with yellow tips and just 

 below the throat it has the same reddish brown band as the 

 old birds. 



The under-parts are yellow with a pale green wash along 

 the sides, the lower tail-coverts greyish yellow. The wing-coverts 

 have also narrow, greyish yellow edgings. The bill is blackish 

 brown. 



The female young bird is much unlike the full-grown. The 

 head is entirely black and a number of the feathers of the back 

 are yellow, the posterior ones with yellow or brownish-yellow 

 tips. The ear-coverts black with olive-green tips. The upper 

 and lower tail-coverts as in the male young bird. The throat 

 and the whole of the lower surface yellow. The bill horn, greyish 

 brown (lower mandible lighter than upper). 



It is noteworthy that one of the old birds has a large, 

 greyish white spot on the posterior half of the upper mandible.

This race was very common in all the above-mentioned 

 localities. 



The males sometimes vary in the colour of the dress, and 

 one of them has not only the upper tail-coverts and rump region 

 olive-green but also the lower back. Another has the whole 

 back black, and so on. 



Likewise, there are differences among the females. The 

 three from Lake Naiwasha, for instance, are all unlike. One 

 has the back entirely black, another (in moult) has the upper 

 part of the back mostly dark-brown, and a third, which is the 

 youngest of the three, has the feathers of the back dark-brown 

 with dark olive-green tips. This last bird has also a pale green 

 wash on the extreme tips of a number of the feathers of the nape.
