The Christmas Island white-eye (Zosterops natalis) is a small passerine bird in the family Zosteropidae, endemic to Christmas Island, an Australian external territory located in the eastern Indian Ocean. White-eyes in the family Zosteropidae are characterized by a ring of white feathers around each eye, short rounded wings, and a brush-tipped tongue suited to nectar and soft fruit feeding, though insects also form an important part of the diet. The Christmas Island white-eye inhabits the tropical rainforest and secondary vegetation across much of the island and is described as an abundant and adaptable species within its extremely limited range. Like all Christmas Island endemics, the species is of high conservation significance given its total dependence on the ecological health of a single small island. Major conservation concerns for the island's wildlife include the yellow crazy ant invasion, which has indirectly damaged large areas of forest through the promotion of scale insect outbreaks causing canopy dieback. Additional pressures include habitat degradation from historical phosphate mining and introduced predators. The white-eye is considered relatively resilient compared to some other Christmas Island endemics, but continued monitoring and invasive species management remain critical.
