SISKIN (See also:Dan. sidsken, Ger. Zeisig and Zeising)  , See also:long known in See also:England as a cage-See also:bird called by dealers the Aberdevine or Abadavine, names of unknown origin, the Fringilla spinus of See also:Linnaeus, and Carduelis spinus of See also:modern writers, belongs to the Passerine See also:family Fringillidae . In some of its structural characters it is most nearly allied to the See also:goldfinch (q.v.), and both are placed in the same genus by systematists; but in its See also:style of coloration, and still more in its habits; it resembles the redpolls (cf . See also:LINNET), though without their slender figure, being indeed rather See also:short and stout of build . Yet it hardly yields to them in activity or in the See also:grace of its actions, as it seeks its See also:food from the catkins of the See also:alder or See also:birch, regardless of the attitude it assumes while so doing . Of an See also:olive-See also:green above, deeply tinted in some parts with See also:black and in others lightened by yellow, and beneath of a yellowish-See also:white again marked with black, the male of this See also:species has at least a becoming if not a brilliant garb, and possesses a See also:song that is not unmelodious, though the resemblance of some of its notes to the See also:running-down of a piece of clockwork is more remarkable than pleasing . The See also:hen is still more soberly attired; but it is perhaps the See also:siskin's disposition to familiarity that makes it so favourite a See also:captive, and, 'though as a cage-bird it is not ordinarily long-lived, it readily adapts itself to the loss of See also:liberty . Moreover, if anything like the needful See also:accommodation be afforded, it will build a See also:nest and therein See also:lay its eggs; but it rarely succeeds in bringing up its See also:young in confinement . As a See also:wild bird it breeds constantly, though locally, throughout the greater See also:part of See also:Scotland, and has frequently done so in England, but more rarely in See also:Ireland . The greater portion, however, of the numerous bands which visit the See also:British Islands in autumn and See also:winter doubtless come from the See also:Continent—perhaps even from far to the 'eastward, since its range stretches across See also:Asia to See also:Japan, in which See also:country it is as favourite a cage-bird as with us . The nest of the siskin is very like that of the goldfinch, but seldom so neatly built; the eggs, except in their smaller See also:size, much resemble those of the See also:greenfinch (q.v.) . A larger and more brightly coloured species, C. spinoides, inhabits the Himalayas, but the siskin has many other relatives belonging to the New See also:World, and in them serious modifications of structure, especially in the See also:form of the See also:bill, occur . Some of these relatives See also:lead almost insensibly to the greenfinch (ut supra) and its See also:allies, others to the goldfinch (ut supra), the redpolls and so on .

Thus the siskin perhaps may be regarded as one of the less modified descendants of a stock whence such forms as those just mentioned have sprung . Its striated plumage also favours this view, as an See also:

evidence of permanent immaturity or generalization of form, since striped feathers are so often the earliest clothing of many of these birds, which only get rid of them at their first See also:moult . On this theory the yellowbird or See also:North-See also:American " goldfinch," C. tristis, would seem, with its immediate allies, to See also:rank among the highest forms of the See also:group, and the See also:pine-goldfinch, C. pinus, of the same country, to be one of the lowest— the See also:cock of the former being generally of a See also:bright yellow See also:hue, with black See also:crown, tail and wings—the last conspicuously barred with white, while neither hens nor young exhibit any striations . On the other See also:hand, neither See also:sex of the latter at any See also:age puts off its striped garb—the See also:mark, it may be See also:pretty safely asserted, of an inferior See also:stage of development . The remaining species of the group, mostly See also:South-American, do not seem here to need particular See also:notice . (A .
