This species closely resembles the last in habits, but is much scarcer round our coasts and generally keeps farther out to sea. It is a rather larger bird than the Common Scoter, and of a dense velvety black, with a small white spot behind each eye and a white bar across the wing. The bill is orange yellow, with a large black basal knob and a narrow dark line along the culmen. Legs orange. The female is brown, rather lighter underneath, and has a dull white patch before, and a smaller one behind, each eye. Bill dark. Legs reddish. Length 22 in.; wing 10·75 in. THE SURF SCOTER Œdemia perspicillata (Linnæus) This North American species has on several occasions occurred on our coasts. The male may be at once distinguished from the other Scoters by the presence of a broad patch of white on the forehead and another on the nape. In the female the nape patch is present though often indistinct. There is no white bar across the wing. Length 21 in.; wing 9·5 in. THE GOOSANDER Mergus merganser, Linnæus The Goosander is the first of the three species of “Sawbills” that are found in this country. Unlike other Ducks, the bill is moderately long and narrow, and both mandibles have a very rough toothed surface enabling them easily to secure and hold their prey, which consists entirely of fish. They are all expert divers. On the east coast of England this species is not uncommon during the winter months, frequenting estuaries and freshwater lakes, but in the south and west it is of irregular occurrence. In Scotland it is known to nest in a few localities, but on the west coast and in Ireland it is decidedly rare. The nest is placed down a hole among rocks, or in a tree, and in Sweden and Lapland it makes extensive use of the nest-boxes put up for it and other species by the Lapps. The eggs, which may be as many as thirteen in number, are creamy white. The note is a very harsh “kaar,” and when swimming this bird is not unlike a Cormorant in general outline. When wounded it will always attempt to escape by diving. The male has the head and neck dark glossy green; back and scapulars brown, passing to grey on the rump; wing coverts white; lower neck and under parts creamy white, tinged with pink in the living bird. Bill and legs red. The female is rufous brown on the head, greyish on the upper parts and flanks, and buffish white below. She is rather smaller than the male. The young resemble the female. Length 25 in.; wing 11 in. THE RED-BREASTED MERGANSER Mergus serrator, Linnæus
