The Bonin white-eye is a small species of songbird endemic to the Bonin Islands of Japan. It is the only species in the monotypic genus Apalopteron.

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 greenfinch, also known as the Ogasawara greenfinch, is a small passerine bird in the finch family Fringillidae that is endemic to the Ogasawara Islands of Japan, where it is found on the Bonin Islands and Volcano Islands. It was formerly considered a subspecies of the grey-capped greenfinch and some authorities consider it as such, but a 2020 analysis found it likely to represent a distinct species that diverged from C. sinica about 1.06 million years ago, and the International Ornithological Congress now recognizes it as such, making it the eleventh endemic species in Japan. There are fewer than 400 individuals in the population and it is considered critically endangered by the Japanese government, necessitating protection. According to the Yamashina Institute for Ornithology, as of December 2021, the Ogaswara greenfinch is Japan's most endangered bird.
