Until 2016 the black-faced grassquit Tiaris bicolor was officially classified with other passerine emberizidae (e.g. antillean bullfinches & sundry New World sparrows). The classifications committee of the American Ornithological Union recently moved them to join tanager-type species, specifically the dome-nesting ones. Now they are considered to be closely related to Darwin’s finches; and they join the broader category that includes tanagers, grosbeaks, and buntings.
