Bonin white-eye
genus of birds
The Bonin white-eye (Apalopteron familiare) is a small species of songbird endemic to the Bonin Islands (Ogasawara Islands) of Japan. It is the only species in the monotypic genus Apalopteron. The taxonomic affinities of the Bonin white-eye were a long-standing mystery and it was formerly placed with the bulbuls, babblers and more recently with the honeyeaters, during which it was known as the Bonin honeyeater. Since 1995 it is known to be a white-eye in the family Zosteropidae, that is closely related to the golden white-eye of the Marianas Islands.
The Bonin white-eye has predominately yellow and green plumage and a conspicuous black triangular patch around the eye – the eye is also surrounded by a broken white ring. It was once found on all the major islands of the Bonin Islands but is now restricted to the islands of Hahajima. On that island group it is found in almost all the habitat types, native and human-modified, although it mostly breeds in native forest. Fruit is an important part of the diet, especially mulberries, as well as insects, but flowers, seeds, spiders and reptiles are taken as well. It feeds both in trees and on the ground, as it is more terrestrial than other white-eyes. Pairs of Bonin white-eyes form long-term pair bonds and remain together throughout the year.
The public source identifies “Bonin white-eye” as genus of birds. This brief keeps that definition visible, then builds a research path around Bonin, white-eye and genus.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Bonin white-eye”, the useful work is to connect “genus of birds” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 28, 2025. The linked authority identifier is Q253644. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
