Four of tbe 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 
105-1*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.
