The nest, as a rule, is placed near the sea, sometimes on the tops of lofty cliffs, and is usually concealed among the coarse grass, heath, and herbage that grow in such situations. It is a hollow lined with fine grass and seaweed, and a quantity of down plucked from the under parts of the sitting-bird. The eggs are five to seven in number, and are smooth, oval in shape, and of a pale dull green colour. The female continues to pluck down from her body during incubation, until the eggs are enveloped in a large mass of it; and on leaving the nest to feed she covers the eggs with the down. At this time the drake is not wholly forgetful of her, and on her appearance, when she leaves her eggs to feed, he usually keeps company with her, and after she has left the water rejoins his male companions. The drake is at all times a shy and wary bird; but in the breeding season the ducks, if not molested, are very tame, and at the Farne Islands the sitting-bird will sometimes allow her back to be stroked, without leaving her eggs. Common Scoter. Œdemia nigra. [Illustration: FIG. 85.--COMMON SCOTER. ¹⁄₁₂ natural size.] Black, the upper parts glossy; central ridge of the upper mandible orange. Length, twenty inches. _Female_: blackish brown above, dark brown below. * * * * * The common, or black scoter, is a large, handsome bird, whose handsomeness is due to its uniform blackness, reminding one of those two familiar beauties and favourites, the blackbird and the domestic black cat; and as with these two--one with splendid yellow eyes, the other with a golden dagger for a beak--so is the scoter’s blackness relieved, and its handsomeness brought out, by a touch of bright orange on the upper mandible. It is the most marine of the diving ducks, and a deep-sea feeder like the long-tailed duck. Its breeding-grounds are in northern Europe, West Siberia, and Iceland, but a few pairs breed annually in the north of Scotland. The nest is a hollow in the ground near the sea, lined with dead leaves and grass, and with down from the sitting-bird. The eggs are eight or nine in number, and of a pale greyish buff. In winter the black scoter visits our coasts in thousands, and is the most common sea-duck. It does not appear to breed until its second year, as large numbers in immature plumage remain on our coasts throughout the summer. The scoter has a harsh cry like that of the tufted duck, and in spring the drake has a love-call, said to be not unmusical. Velvet Scoter. Œdemia fusca.
