198 HARELDA GLACIALIS. 



more acute, express the extent of their winter language. The 

 male is one of the most elegant of the duck tribe They are 

 never seen on land, or on fresh water, except when breeding. 

 On the lakes in Iceland they are numerous. The young 

 usually five. They feed in the same manner as the Eider 

 Duck ; but the bird is altogether more shy and active." 



Young in Winter. — The young when they appear on 

 our coasts have the bill dusky-bluish-grey, the iris brown, the 

 feet grey. In this state they differ little from the adult 

 female, but have the plumage softer, especially on the neck, 

 and the scapulars still shorter, and usually edged with grey, 

 while the white of the lower parts is more or less tinged with 

 brownish-grey on the breast and sides. 



Progress toward MATrRiTY. — It appears that at the 

 age of one year the young assume the adult plumage ; but 

 on this subject I have not been able to make any observa- 

 tions. 



Male in Summer. — At this season the upper part of the 

 head and the nape are brownish black, the sides of the head 

 greyish-white ; the neck all round and the fore part of the 

 breast dark chocolate-brown ; the back and wing-coverts 

 brownish-black; the scapulars similar, but margined with 

 reddish-bi-own ; the quills dark-brown ; the tail as in winter. 



Female in Summer. — The female is of the same colours 

 as in winter.
