The Hoary or Arctic Redpoll (form hornemanni) is described as differing from flammea 'in measurements, structure and plumage', but in reality the differences reflect the more northerly distribution of hornemanni (larger size, whiter plumage). Moreover, there is variation within the plumages of both taxa and they interbreed. Thus the BirdLife Taxonomic Working Group regard them as conspecific.
