Geographic Range
[top]
| Range Description: |
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.

Habitat and Ecology
[top]
| Habitat and 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
|
| Systems: |
Terrestrial |
| Major Threat(s): |
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.
