Irides hazel; bill and legs and toes black. 
The adult females are not only less bright than the males 
but have a distinct wash of olive across the chest. 
One of the November birds and the December one are 
much worn and faded, but the other November bird is still 
quite bright and hardly worn. 
The January and February adults are moulting, the old 
feathers looking much worn and faded against the new 
plumage; but the April bird, except for the head, has com¬ 
pleted the moult. 
Neither of the two young birds is quite fledged ; they 
differ from the adults as follows :— 
“ Above, including head, bright olive - green ; wings 
blackish, broad ends of coverts and outer edges of secondaries 
pale yellow ; beneath, throat very pale yellow; breast 
striped with dull olive-green. 
A common bird in the Tala woods in the Ajo district, to 
which it is a summer visitor, arriving in the early part of 
September and leaving again towards the end of April. 
Miss Bunnacles’ first record of its appearance for the 
summer of 1909 is Sept. 8th. The nest is open and cup¬ 
shaped and composed of twigs lined with feathers. Usually 
very little attempt is made at concealment, it being placed 
in the fork of a low shrub or tree, seldom at any great 
height, and in a more or less open situation. 
The usual clutch of eggs is three, but occasionally four are 
found.
