Taxonomy

The grey-browed brushfinch was often treated as a subspecies of the stripe-headed brushfinch (''A. torquatus''), but was determined a distinct species on the basis of differences in vocalization, plumage, and genetics.Cadena, C. D., and A. M. Cuervo (2009). ''Molecules, ecology, morphology, and songs in concert: how many species is Arremon torquatus (Aves: Emberizidae)?'' Biological Journal of the Linnean Society 99(1): 152-176 The SACC split the group in 2010.
