rdf:langString The Bonin white-eye (Apalopteron familiare) or meguro (メグロ) is a small songbird endemic to the Bonin Islands (Ogasawara Islands) of Japan. It is the only species in the genus Apalopteron. Its taxonomic affinities were a long-standing mystery and it has been 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. They nest in a cup-shaped nest into which usually two eggs are laid. Both parents are responsible for incubation and raising the chicks. The arrival of humans in the Bonin Islands resulted in the extinction of many of the native birds of the islands. The Bonin white-eye was affected by the changes that caused those extinctions, and has lost one subspecies and is no longer found on many groups of the Bonin Islands. The species is an important part of the ecology of the Bonin Islands, an important seed disperser for the native plants. It has proven to be somewhat resilient to competition from introduced warbling white-eyes, predation by introduced rats and cats, and habitat loss. The Bonin white-eye is evaluated as being "near threatened" by the IUCN Red List of Threatened Species.
