less bright, the black on the throat less pronounced, and the black 

 stripes on the under surface less strongly marked, it might be said 

 to be exactly like the male. , 



Young male in ivinter plumage. Uniform above, the back olive- 

 yellow, beneath which may be found the black centres to the 

 feathers on disturbing the plumage ; across the rump a band of 

 bright yellow ; upper tail-coverts black, edged with grey ; wings 

 and tail as in the adult female, with a double wing- bar formed by 

 the white tips to the median and greater coverts ; head and neck 

 entirely ashy grey, which colour also overspreads the mantle ; the 

 whitish eyebrow ill-defined and obscured with ashy ; a distinct 

 whitish eyelid ; lores ashy whitish ; ear-coverts pale ashy brown 

 like the sides of the neck, slightly washed with olive ; cheeks and 

 throat bright yellow, the fore neck and lower throat more ashy ; 

 remainder of under surface of body bright yellow, the flanks with 

 half-concealed streaks of black ; abdomen, under tail-coverts, axil- 

 larios, and under wing-coverts white. 



The great difference between the old and the young birds in this 

 species consists in the uniform olive-yellow back and pale ashy-grey 

 head and neck of the latter as well as in the absence of black streaks 

 on the breast, these being confined to the sides of the body.
