The cardueline finches are a subfamily, Carduelinae, one of at least three subfamilies of the finch family Fringillidae, the others being the Fringillinae and the Euphoniinae. The Hawaiian honeycreepers are usually now considered in this subfamily.[1] Cardueline finches are specialised to eating seeds, and unlike most passerine birds, they feed their young mostly on seeds, which are regurgitated.[2] Besides this, they differ from the other finches in some minor details of their skull.[2] They are adept at opening seeds and clinging to stems, unlike other granivorous birds, such as sparrows and buntings, which feed mostly on fallen seeds.[3] Some members of this subfamily are further specialised to feed on a particular type of seed, such as cones, in the case of crossbills.[2] Carduelines forage in flocks throughout the year, rather than keeping territories, and males defend their females rather than a territory or nest.[4]

The following genera are those usually considered the Carduelinae:
