Indian White-eye
Zosterops palpebrosus
This bird is small (about 8–9 cm long) with yellowish olive upper parts, a white eye ring, a yellow throat, and a vent. The belly is whitish-grey, but may be yellow in some subspecies. The sexes look similar. The species is widespread and belongs to a superspecies complex that includes Zosterops japonicus, Zosterops meyeni, and possibly others. The group's taxonomy is still unclear, with some island populations distinctive while others lack strong support. The population from Flores, Indonesia, for instance, is found closer to the pale white-eye.
