The Redpolls are a group of small passerine birds in the finch family Fringillidae which have characteristic red markings on their heads. They were formerly placed into the genus Acanthis together with the linnets and the twite, but their closest relatives are actually the crossbills, that are placed in the genus Loxia. The latter genus could be merged with Carduelis in a single genus, for which the name Loxia would then have priority. But this would imply to change the name of a large number of species, and as their adaptations and biogeography are evolutionarily quite peculiar, it would be better to reinstate Acanthis instead, including only the redpolls. There are several different very closely related forms of redpolls which could be considered as anything from one to five species. Recent studies tend to support three species, but this is certainly not definite.
