, 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
