A bird of the family Rallidae (illustration) in the order Gruiformes. It is endemic to the main island of Okinawa, and lives as a resident bird in the mountain forests in the northern part of the island. Yanbaru is another name for the Kunigami region in the northern part of the island, where this species was discovered. Total length is about 30 cm. The head and back are dark olive brown, the face and throat are black, and there is a white spot behind the eye. The underside below the upper chest is striped black and white, and the beak and legs are red. In juvenile birds, the black parts of the face and the patterns on the underside are not as clear as in adults, and the beak is blackish. They live alone in pairs in forests or in thickets near wetlands, and spend most of their time on the ground, but are said to sleep in trees at night.
