He is a winter inhabitant of the States; is found on the seas, fresh water lakes and rivers, and bears many different appellations, such as the Water Pheasant, the Sheldrake, the Fisherman, and the Diver. The name Goosander is a popular misnomer, because no one of all the nine species of the genus Mergus has either the appearance or the habits of geese of any description. They have the bill rather longer than the middle size, and much more slender and hard in its texture than the bills of ducks, not being a dabbling or sentient bill like theirs, but prehensile and of a very peculiar form. The mandibles are straight for a greater part of their length, but the upper one is much hooked at the point, and very sharp, and the cutting edges of both mandibles are in all their length beset with short, but strong and sharp teeth inclining backward. The bill is thus fitted for taking a very firm hold of slippery prey, and its skill in capturing fish proves how effective is this simple apparatus. The Goosander, from having its legs far backward, is an awkward walker, while it does not dive so well as the proper diver, yet, by the arrangement of its bill, it is enabled to levy far more severe contributions upon fish-ponds than any birds which resort to such places, not even excepting the herons. Their wings are of moderate length, but clean and firmly made, and the plumage of the body is also firm and compact, so that the power of flight is considerable, and when necessary it can be extended to long distances without much fatigue. As is the case with the ducks, there is an enlargement of the pulmonic end of the trachea, which probably answers the purpose of a magazine of air, and enables the birds to remain much longer under water than they could do if not thus provided. The general color of the bill is red; but a portion round the nostrils, the ridge of the upper mandible, and the nail on its tip are dusky. The inside of the gape is bright orange; the head and the crest, the last of which is most conspicuous in the male, together with the upper part of the neck, are dark green, passing into black on the chin and throat; the lower part of the neck, the outer scapulars, the breast, and all the under part of the body, are white, with a tinge of yellowish-red. The back and the scapulars next the back are black, fading into grayish toward the rump; and the tail, which consists of eighteen pointed feathers, is of a gray color. The principal quills and coverts are brownish-black, with the exception of the middle secondaries and the extremities of their coverts, and these form a white speculum or wing-spot. The head and neck of the female are rust color, the upper part is of a grayish tint, and the under part white, with a yellowish shade. In consequence of this she has been figured and described as the Dun Diver; and the young male, which resembles her in color, has been considered as the male of the same. The bill and feet are reddish ash color.
