A large, little-known flightless rail from Sulawesi. Note the heavy bill, orange in females, duller in males, and the tailless appearance. Gray with an orange nape and contrastingly rufous wings. Note dense barring on belly. A rarely seen terrestrial bird of densely-vegetated forest floor in lowlands and foothills; sometimes occurs in nearby dense scrub too. Much larger and heavier-billed than Slaty-breasted Rail, and further differs in showing conspicuous rufous wings. Vocalizations include a low-pitched “mmmm” and wheezing and snoring noises.
