Chichi-jima (Father Island), formerly known as Peel Island, is the largest island in the Ogasawara archipelago. Chichi-jima is approximately 150 miles north of Iwo Jima. The island is within the political boundaries of Ogasawara Town, Ogasawara Subprefecture, Tokyo, Japan.
Possibly as a result of the introduction of alien animals, at least three species of birds became extinct: the Bonin Nankeen Night Heron, Bonin Grosbeak a finch, and Bonin Thrush. The island was the only known home of the thrush and probably the finch, although the heron was found on Nakōdo-jima as well. The existence of the birds was documented by von Kittlitz in 1828, and five stuffed thrushes are in European museums.
The Bonin Wood-pigeon died out in the late Nineteenth century, apparently as the result of the introduction of alien mammals, or from both causes. The species is known to have existed only on Chichi-jima and another island, Nakōdo-jima.
