The Daito wren is a controversial subspecies of the Eurasian wren. It is known only by the type specimen, a male collected in 1938 on Minami Daitō-jima, the main island of the Daito Archipelago east of Okinawa. Yamashina described the bird as a new subspecies after comparing it with 114 specimens from surrounding areas and under the impression that the Eurasian wren is a fairly sedentary bird, not liable to be drifted astray over long distances. Its scientific name honors Yamashina's specimen collector, Hyojiri Orii.
The Bonin grosbeak or Bonin Islands grosbeak is an extinct finch. It is one of the diverse bird taxa that are vernacularly called "grosbeaks", but it is not closely related to the grosbeaks sensu stricto. Many authorities place the species in the genus Carpodacus, but some place it in its own genus, Chaunoproctus. A 2013 genetic analysis found it to be a relatively basal member of the group, more derived than the common rosefinch, but with no close relatives, with an estimated divergence time from other members of the group around 12.5 million years ago.
The Bonin nankeen night heron is an extinct subspecies of the nankeen night heron.

The collared kingfisher is a medium-sized kingfisher belonging to the subfamily Halcyoninae, the tree kingfishers. It is also known as the white-collared kingfisher, black-masked kingfisher or mangrove kingfisher. It has a wide range extending from the Red Sea across southern Asia to Polynesia.

The Society kingfisher or Tahiti kingfisher is a species of bird in the family Alcedinidae. It is endemic to the Society Islands of French Polynesia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
Winchell's kingfisher or the rufous-lored kingfisher, is a species of bird in the family Alcedinidae, the kingfishers. It is endemic to the Philippines, its natural habitat being lowland forests.

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.
The JapaneseRed List is the Japanese domestic counterpart to the IUCN Red List of Threatened Species. The national Red List is compiled and maintained by the Ministry of the Environment, alongside a separate Red List for marine organisms. Similarly drawing on the relevant scientific authorities, NGOs, and local governments, the Ministry of the Environment also prepares and publishes a Red Data Book that provides further information on species and habitats.
Orii Hyōjirō was a Japanese specimen collector of birds and mammals. At least a hundred new species and subspecies were described based on the type specimens he collected, a 2014 review putting the total, among taxa currently recognized, at 14 species and 41 subspecies of mammal, and 6 species and 68 subspecies of bird. The 7 mammal and 10 bird taxa named in honour of "Orii of the Orient", as he came to be known, include the Ryūkyū shrew and now-extinct Daitō varied tit.
