The Chestnut-capped Brush Finch, Arremon brunneinucha, is a  passerine bird  which breeds in highlands from central Mexico to southeastern Peru. Despite its name, it is not a true  finch, but rather a member of the large Emberizidae family, which also includes buntings,  American sparrows,  juncos and towhees. Until recently, it was generally placed in the genus Buarremon, while it occasionally has been placed in Atlapetes.
