Sulawesi-Erddrossel Zoothera heinrichi

A distinctive long-tailed thrush from Sulawesi. Graduated tail often appears abraded. Upperparts dark, with slate-colored back and wings. Wings show a rufous flash. Underparts warm rufous-orange in color, uniform in adults but variably speckled below in young birds, particularly around the throat. A shy terrestrial thrush that forages on forest floor and trails, found very locally in montane areas. Told from Island and Sulawesi Thrushes by notably longer tail, lack of black brow, and absence of dark throat. Largely silent; song unknown, but high-pitched whistle has been reported.
