DESCRIPTION OF THE PLUMAGE. 
Adult Male in Spring.—The upper parts are olive green, 
slightly darker on the crown, but somewhat lighter on the 
rump. The wings and tail are brown, the feathers being 
edged with much the same colour as the back, though a little 
more greenish. ‘The outer edge of the outermost tail-feather 
and primary is light brown. The greater secondary wing- 
coverts are olive brown tipped with white, and the median 
coverts, bastard wing, and primary coverts olive. Thus there 
is only one light bar across the wing. There is a distinct 
whitish yellow superciliary stripe, the lores are ash grey, and 
the sides of the head light olive green. The under parts 
generally are buffish white, but slightly more olive buff on the 
sides of the breast and flanks, and the under surface of the 
wings and tail is ash grey, the feathers having white shafts. 
Upper wing-coverts are light sulphur yellow. Upper mandible 
is dark brown, and the lower brown at the tip, but buff colour 
at the base. Iris is dark brown, and feet brownish olive. 
In winter the plumage is duller. 
The young resemble the adults, but the colouring is not 
so bright.
