The Sulawesi Thrush, *Zoothera heinrichi*, is a medium-sized and exceptionally secretive songbird endemic to the montane forests of Sulawesi, Indonesia.

Primarily inhabits dense, damp undergrowth of montane and lower montane primary forests, typically at elevations between 1,000 and 2,300 meters (3,300-7,500 feet).
Primarily insectivorous, feeding on a variety of invertebrates such as worms, beetles, and other arthropods found in leaf litter, supplemented occasionally by small fruits or berries. It forages by gleaning and flicking leaves on the forest floor.
