See H. zosterops. Formerly considered conspecific with H. inornatus. Despite marked plumage differences between some races and remarks about vocal distinctiveness of certain taxa#R#R, all available recordings (none found for septentrionalis, chiribiquetensis, duidae or breweri) reveal very similar songs#R. Recently described isolated race chiribiquetensis demonstrates closer affinity to Andean forms than to nearby tepui populations. Race septentrionalis perhaps indistinguishable; may be better merged with impiger. Nine subspecies recognized.
