brown; feathers of the head and neck being of a lighter

of the beak runs down to the level of the nostrils; in the 
Common Hider this line hardly reaches a point mid-way 
between the base of the beak and the nostrils.

tive nuptial plumages.

plumage.

This, the least of the three Eider Ducks in size, is an 
exceedingly rare wanderer from the Arctic seas. It has 
been twice recorded from England. A male was killed on 
February 10th, 1830, near Caistor, in Norfolk. It is now 
in the Moen Museum (A. Patterson, ‘ Zoologist,’ 1900, p. 
532). The second specimen was obtained from Filey Brigg, 
Yorkshire, on August 15th, 1845, by the late Mr. G. N. 
Curson. It is in the collection of Lord Scarsdale, at 
Kedleston (Yarrell).
