preceding winter. The brown hood is acquired, and the 

 white of the lower parts is faintly tinged with red. An

 several others, may be described as follows : — • 



The bill brownish-red, of a deeper tint at the end ; bare 

 margins of eyelids also deep red, iris dusky ; feet pale brown- 

 ish-red, claws blackish-brown. The head, and a small portion 

 of the neck greyish-brown, that colour descending more on 

 the throat than on the nape ; a narrow white space on the 

 eyelids, excepting their fore part. The neck, lower parts, 

 upper tail-coverts, and tail white ; the back and wings very 

 pale bluish-grey ; the middle wing-coverts pale brown tOAvard 

 the end, tipped with whitish. The outer web, margin of 

 inner web, and terminal part of the first quill, blackish - 

 brown ; part of the outer web toward the end, the tip, and 

 inner margin of the next three, also blackish-brown, as are 

 the inner margins of all the other primaries ; the secondaries 

 have a brown patch near the end, their tips white. The 

 tail-feathers with a narrow bar of pale blackish-brown at the 

 end. It thus appears, that although the smaller feathers are 

 changed in spring, the quills and tail-feathers remain until 

 the autumnal moult. 



Second Winter. — The wdnter plumage is now as 

 described in the adult, and the bill and feet are deep red.
