Four of the above-mentioned individuals are more or less 

 immature, judging from the rufous margins on the upper 

 wing-coverts and primaries. 



A young bird, in the British Museum, is distinguished 

 from the adult more particularly by its brown upper surface, 

 though it is blackish on the crown, and the feathers are 

 everywhere margined with rufous ; there is no trace of any 

 yellow or orange to the bases of the feathers on the head, 

 the yellow of the under surface is paler and more inclining 

 to sulphur-yellow. 



Three eggs, collected November 25, 1902, are creamy 

 white blotched and streaked with brown, particularly at the 

 larger end, and shew underlying spots of lead-grey. Axis 

 1-05-1-1 inch; diam. 0'8. 



The nest is loosely constructed of white grass with a few 

 pieces of creeping plants interwoven. 



This bird is resident but not common, according to 

 Mr. Foster.
