POCHARD, POCKARD , Or See also:POKER,' names properly belonging to the male of a See also:species of See also:duck (the See also:female of which is known as the Dunbird), the Anas ferina of See also:Linnaeus, and Nyroca ferina of later ornithologists—but names very often applied by writers in a See also:general way to most of the See also:group or sub-See also:family Fuligulinae, commonly called Diving or See also:Sea-Ducks (see DUCK). The Pochard in full plumage is a very handsome See also:bird, with a coppery-red See also:bead, on the sides of which sparkle the See also:ruby irides of his eyes, relieved by the greyish-See also:blue of the basal See also:half of his broad See also:bill, and the deep See also:black of his See also:breast, while his back and flanks appear of a See also:light See also:grey, being really of a dull See also:white closely barred by See also:fine undulating black lines. The tail-coverts both above and below are black, the See also:quill feathers brownish-black, and the See also:lower See also:surface of a dull white. The Dunbird has the See also:head and See also:neck reddish-See also:brown, with See also:ill-defined whitish patches on the cheeks and See also:chin; the back and upper tail-coverts are dull brown, and the See also:rest of the plumage, except the lower tail-coverts, which are brownish-grey, resembles that of the Pochard. This species is very abundant in many parts of See also:Europe, See also:northern See also:Asia, and See also:North See also:America, generally frequenting in See also:winter the larger open See also:waters, and extending its migrations to See also:Barbary and See also:Egypt, but in summer retiring northward and inland to breed. The See also:American Pochard is slightly larger, has yellow eyes, and is now regarded as specifically distinct under the name of Nyroca americans; but America has a perfectly distinct though allied species in the celebrated See also:canvas-back duck, N. vallisneria, a much larger bird, with a longer, higher and narrower bill, which has no blue at the See also:base, and, though the plumage of both, especially in the See also:females, is very similar, the male canvas-back has a darker head, and the black lines on the back and flanks are much broken up and farther asunder, so that the effect is to give these parts a much lighter See also:colour, and from this has arisen the bird's See also:common though fanciful name. Its scientific epithet is derived from the fresh-See also:water plant, a species of Vallisneria, usually known as " See also:wild See also:celery," from feeding on which its flesh is believed to acquire the delicate flavour that is held in so See also:great a repute. The Pochard and Dunbird in Europe are in much See also:request for the table (as the See also:German name of the species, Tafelente, testifies) when they frequent fresh-water; birds killed on the sea-See also:coast are so See also:rank as to be almost worthless. Among other species nearly allied to the Pochard that frequent the northern hemisphere may be mentioned the See also:Scaup-Duck, Fuligula See also:manila, with its American representative F. affinis, in ' The derivation of these words, in the first of which the ch is pronounced hard (though Dr See also:Johnson made it soft), and the o in all of them generally See also:long, is very uncertain. See also:Cotgrave has f.ocheculien (See also:modern See also:French poche-cuiller), which he renders Shoueler," nowadays the name of a See also:kind of duck, but in his See also:time meaning the bird we commonly See also:call See also:Spoonbill (q.v.). Littr6 gives pochard as a popular French word signifying drunkard.both of which the male has the head black, glossed with blue or See also:green; but these are nearly always uneatable from the nature of their See also:food, which is mostly gathered at See also:low See also:tide on the " scaups " or " scalps,"—as the See also:banks on which mussels and other marine molluscs grow are in many places termed. Then there are the Tufted Duck, F. cristata—black with a See also:crest and white flanks—and its American See also:equivalent F. collaris, and the White-eyed Pochard, F. nyroca, and the Red-crested Pochard, F. rufina—both See also:peculiar to the Old See also:World, and well known in See also:India.

In the See also:

southern hemisphere the genus is represented by three species, F. capensis, F. australis and F. novae-zealandiae, whose respective names indicate the See also:country each inhabits, and in See also:South America exists a some-what divergent See also:form which has been placed in a distinct genus as Metopsana peposaca. Generally classed with the Fuligulinae is the small group known as the Eiders, which differ from them in several respects: the bulb at the base of the trachea in the male, so largely See also:developed in the members of the genus Fuligula, is here much smaller and wholly of See also:bone; the See also:males take a much longer time, two or even three years, to attain their full plumage, and some of the feathers on the head, when that plumage is completed, are always stiff, glistening and of a peculiar See also:pale-green colour. This little group of hardly more than half a dozen species may be fairly considered to form a See also:separate genus under the name of Somateria. Many authors indeed have—unjustifiably, as it seems to the See also:present writer—broken it up into three or four genera. The well-known See also:Eider, S. mollissima, is the largest of this group, and, beautiful as it is, is excelled in beauty by the See also:King-Duck, S. spectabilis, and the little S. stelleri. A most interesting form generally, but obviously in See also:error, placed among them, is the Logger-head, Racehorse or Steamer-Duck, Micropterus (or more probably Tachyeres) cinereus of See also:Chile, the See also:Falkland Islands and Straits of See also:Magellan—nearly as large as a tame See also:goose, and subject to the, so far as known, unique peculiarity of losing its See also:power of See also:flight after reaching maturity. Its habits have been well de-scribed by C. See also:Darwin in his See also:Journal of Researches, and its See also:anatomy is the subject of an excellent See also:paper in the Zoological Society's Transactions (vii. 493-501, pls. lviii.-lxii.) by R. O. See also:Cunningham. (A.
