BRITISH BIRDS. 



The intermediate stages of plumage are unknown; but birds of the 

 year have a broad black band margined with brown at the end of the tail ; 

 and the scapulars, innermost secondaries, and most of the wing-coverts are 

 similarly coloured. 



Young in first plumage do not differ much from adults in winter 

 plumage in the colour of their wings and underparts, but the narrow pale 

 brown margins and broad dark sub-margins are conspicuous on nearly every 

 feather of the upper parts. 



Young in down are described by Middendorff as rusty yellow above and 

 whitish grey below, the throat and upper breast and the whole of the 

 upper parts being spotted with black.
