The white-browed brush finch (''Arremon torquatus'') is a species of bird in the Emberizidae family. It is found in north-western Argentina, Bolivia, and southern Peru. It is generally common in forest and dense second growth, mainly at altitudes of , but locally it occurs at far lower altitudes.〔Ridgely, R. S., & G. Tudor. (1989). ''Birds of South America. The Oscine Passerines.'' Vol. 1. Oxford University Press. ISBN 0-19-857217-4〕 ==Taxonomy== Until recently, the white-browed brush finch was placed in the genus ''Buarremon''.〔Cadena, C. D., J. Klicka and R. E. Ricklefs. (2007). ''Evolutionary differentiation in the Neotropical montane region: molecular phylogenetics and phylogeography of Buarremon brush-finches (Aves, Emberizidae).'' Molecular Phylogenetics and Evolution. 44(3): 993-1016.〕 Considerable racial variation existed in the formerly named stripe-headed brush finch, and based on ecology, morphology, song, and molecular work it was recently suggested that it be split into eight species.〔Cadena, C. D., and A. M. Cuervo (2009). ''Molecules, ecology, morphology, and songs in concert: how many species is Arremon torquatus (Aves: Emberizidae)?''
