Oriental White-eye (Zosterops palpebrosus) - HBW 13, p. 446

Taxonomy: Sylvia palpebrosa Temminck, 1824, Bengal, India.
Forms a superspecies with Z. japonicus and Z. meyeni, and sometimes considered conspecific with either or with both, but all appear morphologically distinct; interbreeding with Z. japonicus occurs in S China and N Vietnam. Was formerly considered to form a species complex with Z. salvadorii and Z. everetti: in that arrangement, race siamensis treated as a full species, auriventer (together with race tahanensis of Z. everetti) as another species, melanurus and unicus then constituting a third species, and remaining races of present species (together with Z. salvadorii and remaining races of Z. everetti) forming the fourth species. Z. salvadorii and Z. e. everetti, however, now believed to be more distantly related to present species. Otherwise, populations in neighbourhood of Mt Pangrango, in W Java, are intermediate between races buxtoni and melanurus. Races egregius and salimalii possibly better subsumed in nominate. Birds of this species recorded in Cambodia of uncertain racial identity, provisionally included in williamsoni; those in Andaman Is currently included in nicobaricus, but possibly represent an as yet undescribed race. Proposed races joannae (described from SE Yunnan, in China) and occidentis (Shimla, in N India) are synonymized with nominate, and amabilis (Kathiawar Peninsula, in W India) is merged with egregius. Eleven subspecies currently recognized.
