General Sabine states (in the Appendix to Sir E. Parry's first Voyage) that these birds were abundant in the North Georgian Islands, their nests being placed on the ground in the neighbourhood of fresh-water ponds, and their food consisting of the aquatic vegetation. Sir J. C. Ross says, "Vast numbers of this beautiful Duck resort annually to the shores and islands of the Arctic Regions in the breeding season, and have on many occasions afforded a valuable and salutary supply of fresh provision to the crews of the vessels employed on those seas. On our late voyages comparatively few were obtained, although seen in very great numbers. They do not retire far to the south in the winter, but assemble in large flocks, the males by themselves, and the females with their young brood are often met with in the Atlantic Ocean, far distant from any land, where the numerous crustaceans and other marine animals afford them abundance of food." This species, which very rarely occurs in Great Britain, was found, on one occasion, according to Dr. Latham, about June, at Papa Westra, one of the Orkney Islands. The eggs, six in number, rather smaller than those of the True Eider Duck, were embedded in down, and placed on a rock overhanging the sea. Nuttall states that the eggs of this bird are whitish, while Yarrell describes them as pale green, and Audubon as of a uniform dull greenish hue. Latham tells us that in Greenland, where the King Ducks are common, the natives assemble in canoes, and by their shouts terrify the birds, which dive to avoid them; but as the place where they are about to emerge is betrayed by the bubbling of the water, their pursuers follow them, and the same game being several times repeated, the birds are at length tired out and easily secured. * * * * * The WESTERN or STELLER'S EIDER DUCK (_Somateria_ or _Heniconetta Stelleri_) is a smaller species, still more beautifully coloured and marked. In the male the head, nape, and sides of neck are white, a spot on the forehead, and a transverse band at the back of the head are green, a circle round the eye, the fore and hinder neck, the rump, tail, and points of the quills are black. The upper wing-covers and shoulders are white, striped with dark blue. The under side, as far as the blackish brown centre of the belly, is yellowish brown. In the plumage of the female reddish brown predominates. The eye is brown, the beak grey, and the foot greenish grey. The Western Eider Duck was first described by Steller, from specimens which he obtained in Kamschatka, where it builds on inaccessible rocks. But few specimens of this rare Duck have been shot in England. This species is exclusively a sea bird, is never seen entering the estuaries of rivers, and breeds among rocks and precipices. It flies in large flocks. * * * * *
