Locustella castanea
Sulawesi Bush Warbler belongs to Old World warbler in the family Locustellidae. Notable features include a preference for moss-covered rocks and tree trunks densely clad with vines. On Seram it frequents lower mountain slopes in Lithospermum and Castanopsis woodland with Shorea, Agathis and Dacrydium trees, ferns and mosses, and also dense patches of bamboo. It often flicks its wings over its back and cocks its tail slightly. (Wikipedia, general species account).
Its natural range is restricted to the island of Sulawesi in Indonesia where it is found on the forest floor. There are two subspecies: L. c. castanea (Büttikofer, 1893) - most of montane Sulawesi aside from the southwest L. c. everetti (Hartert, 1896) - southwestern montane Sulawesi The Sulawesi bush warbler is found in undisturbed primary montane forest and in secondary forest, as well as adjoining thick scrub, bushes and rank grassland.
