Zosterops japonicus

Decima, Nagasaki, Japan

.

Sometimes considered conspecific with either or both of Z. meyeni and Z. palpebrosus; hybrids with Z. palpebrosus found in S China and N Vietnam; sometimes only N race batanis of Z. meyeni placed within present species. Affinity to Z. erythropleurus unclear. Geographical variation possibly partly clinal, as N races large, dark and have somewhat brownish or buffy flanks, whereas smallest and brightest races occur in S of range (Hainan), but apparently a marked difference between island and continental forms, latter being smaller, with much paler, buffier flanks and typically yellow lores and frons (and race hainanus notably small); further study required. Races stejnegeri and alani interbreed in Ogasawara (Bonin) Is (where both introduced); hybrids named as boninsimae. Other proposed races are yesoensis (described from Muroran, on Hokkaido), which is synonymized with nominate, and, in S Ryukyus, iriomotensis (Iriomote) and yokakuni (Yonaguni), which are subsumed into loochooensis. Eight subspecies recognized.

  • Z. j. daitoensis Nagamichi Kuroda, 1923 – Borodino Is (Kita-daito-jima and Minami-daito-jima).
  • Z. j. stejnegeri Seebohm, 1891 – Oshima (Izu Is) S to Torishima (Nanpo Archipelago).
  • Z. j. alani E. J. O. Hartert, 1905 – Iwo (Volcano) Is (Kita-iwo-jima, Iwo Jima).
  • Z. j. simplex Swinhoe, 1861 – Chinese White-eye – E China (extreme S Gansu E to Jiangsu, S to Sichuan, E Yunnan, Guangxi, Guangdong and Fujian) and Taiwan and extreme NE Vietnam (E Tonkin); non-breeding SE China S to Thailand and C Indochina.
  • Z. j. hainanus E. J. O. Hartert, 1923 – Hainan.
  • Races stejnegeri and alani introduced on Ogasawara (Bonin) Is, where both interbreed. Nominate race introduced in Singapore and Hawaii (established on all the main islands).
