At present, the Bonin white-eye population is declining. The biggest threat is habitat loss, with nearly all of the original subtropical forest habitat of the Bonin white-eye having been cleared. Habitat loss is one of the main factors that has led to the extinction of this species on several islands (4).
Human settlement on the Ogasawara Islands in 1830 resulted in the introduction of the domestic cat (Felis catus) which quickly became feral. The number of cats now on the island is believed to be in the hundreds, and this is having an adverse effect on numbers of the Bonin white-eye (5).
The Bonin white-eye is especially at risk from economic development on Haha-jima, as a result of development for tourism. This is because of the consequent reduction in forest cover on the islands (4) (6).
