axillaries fades as the plumage gets worn, and these are often pale ashy like the sides of the body. 
Both the upper parts arid the breast become greyer and paler during the breeding-season. 
In winter plumage the bill is dark brown or horn-brown, generally with a little yellow on the 
lower mandible, but there is a distinct buff shade on the throat, pervading also the breast and sides 
of the body. Тһе upper surface is also distinctly browner: **feet slate-colour; iris dark brown" 
(H. Durnford). 
Young birds are rather darker olive-brown than the adults, and have longitudinal buff streaks 
to the feathers of the head and back; the throat is white with a few black spots, but a very distinct 
white gular patch, as in the adults; the lower throat and fore-neck are buff, broadly barred with 
black tips to the feathers, and the sides of the body are also light tawny-buff, more narrowly 
barred with blackish. 
The figure in the Plate is drawn from a Bahia skin in the Seebohm Collection, and the 
descriptions are taken from the series in the British Museum. [R. B. 5.]
