THE COMMON EIDER, 
Steller’s Duck (. Polysticta stelleri ) is a very rare bird at present, and is, seemingly, 
gradually coming to the same late as the preceding species. It is a striking bird in its mark-

both hemispheres. 
Audubon describes this as Western Duck, and says : “ This beautiful Duck, which was dis-

As it is found in England occasionally, Audubon made his figure from a specimen in the 
Norwich, England, Museum. 
It is a small Duck, being only sixteen inches in length.

The Eider Duck is only a winter visitant to the more northern portions of Europe. 
This bird is widely celebrated on account of the exquisitely soft and bright down which 
the parent plucks from its breast and lays over the eggs during the process of incubation. 
Taking these nests is with some a regular business, not devoid of risk on account of the pre-

The Common Eider ( Somateria mollissima) inhabits both hemispheres. With us its 
breeding-range reaches south from the Arctics to Maine, where it is called Squam Duck. 
Wilson says : “ The quantity of down found in one nest more than filled the crown of a hat, 
yet weighed no more than three-quarters of an ounce ; and it is asserted that two pounds of
