The Bonin thrush, Bonin Islands thrush or Kittlitz's thrush (Zoothera terrestris) is sometimes separated as the only species of the genus Cichlopasser. It is an extinct species of Asian thrush. The only place where this bird ever was found is Chichi-jima in the Ogasawara Islands; it might theoretically have also occurred on Anijima and Otōtojima, but this is not borne out by observations or specimens. The species was only once observed by a naturalist, its discoverer Heinrich von Kittlitz.
