Summary Chaunoproctus ferreorostris is only known from specimens collected in 1827 and 1828 on Chichi-jima, Ogasawara-shoto (Peel Island, Bonin), Japan¹. It could not be found on Peel by Simpson in 1854, but may have survived until 1890, when it was reported to Holst by locals².

Ecology: Nothing is known of its ecology² apart from Kittlitz's description, "this bird lives on Bonin-sima, alone or in pairs, in the forest near the coast. It is not common but likes to hide, although of a phlegmatic nature and not shy. Usually it is seen running on the ground, only seldom high in the trees."¹

Threats It seems reasonable to surmise from its ecology that its extinction resulted from the deforestation of the islands, and the introduction of cats and rats³.
