Original HBW caption:
In the 1960s it was suggested that since the Spectacled Finch bears a resemblance to the European Goldfinch (Carduelis carduelis), it might be a Palearctic relict evolved from an ancestral goldfinch. Its plumage pattern also looks like a cross between a Carpodacus rosefinch and a Eophona grosbeak. Recent molecular work places it close to a group of finch genera that occur in rather extreme and arid environments, including Carpodacus and the Leucosticte mountainfinches. Like the Spectacled Finch, several other species in this group belong to monotypic genera, including the Long-tailed Rosefinch (Uragus sibiricus) and the Mongolian Finch (Eremopsaltria mongolica).
