Plumage velvet-black, except a small white patch behind the eye and a conspicuous white bar across the wing; bill apricot-yellow, with a black tubercle at the base; irides white; legs and toes orange-red; webs black. Length, twenty-two inches. Female: sooty brown; a large dull white patch before, and a smaller one behind, the eye; speculum less defined than in the male.
Mr. Abel Chapman, comparing this species with the last described, has given the best picture of it. He says: ‘The velvet scoter is a larger and handsomer species, the jet-black plumage of the old drakes being peculiarly rich and glossy, and is easily distinguished at any distance by the broad white speculum on the wings, closely resembling an old black cock, if one could imagine such a bird far out at sea.’ It is not known whether the velvet scoter breeds in Scotland or not. In summer it is found on inland lakes in Scandinavia and Northern Russia, and it visits our coasts in winter, but not in such large numbers as the common scoter. It is not so exclusively marine in its habits as that species.
Goosander.
Mergus merganser.
Fig. 86.—Goosander. ¹⁄₁₂ natural size.
Bill and irides blood-red; head and upper neck glossy dark green; lower neck and under parts white tinged with salmon-pink; upper back and scapulars black; wing-coverts white; primaries and some of the secondaries ash-brown; lower back and tail ash-grey; legs and feet orange-red. Length, twenty-six inches. The female is less conspicuously coloured, and has a reddish brown head and neck.
The mergansers are sea-ducks of slimmer and more elegant forms than the species already described, and differ from scaups, eiders, and scoters as terns differ from gulls. They have grebe-like necks and long, slender, serrated bills, and a variegated plumage with strongly contrasted colours.
The goosander is the largest of the three British species, and is not uncommon in winter on some parts of the coast, and is abundant in the west districts of Scotland. Its visits to the coasts of England and Ireland occur chiefly in severe seasons. It is also a breeder in the Highlands of Scotland. In its summer haunts in Scandinavia and north of the arctic circle the goosander affects rivers and inland lakes, but is also found on the sea-coast. But whether on sea or lake, the water is its element; and being somewhat grebe-like in form, with the legs placed very far back, it sits erect, and moves with difficulty on land. On the water it submerges its body when swimming like the cormorant, and, like that bird, preys on fish, pursuing and capturing them under water.
