Ishigaki, southern Ryukyu Islands.
Until recently considered conspecific with F. narcissina and F. elisae, but genetically, vocally and morphologically distinct#R#R#R, differing from latter in characters given under that species and from F. narcissina, provisionally, by its dark green-grey vs black crown to mantle (3); yellow vs orange-yellow supercilium (1); fainter orange tinge to breast (1); song with shortest phrases (2) and narrowest frequency range (2)#R. However, acoustic samples are from Okinawa and genetic samples from Iriomote#R; race jakuschima, closest to F. narcissina in size and plumage, unsampled, so separation of present species tentative; more research needed. Races jakuschima and shonis both largely ignored in recent treatments, but they show a stepped-clinal N–S transition from the large colourful F. narcissina to the small, plainer nominate of present species, and are reinstated here. Three subspecies currently recognized.
