Dulit Partridge

Endemic to the mountains of Borneo and known from only eight specimens collected between 1894 and 1902. Nothing is known about this species' ecology, but based on the few specimen data available, it presumably replaces the similar Long-billed Partridge (R. longirostris) of Borneo's lowlands and probably occupies mid-elevation forests (~900-1200 meters).

Endemic to the mountains of Borneo, where eight specimens were collected (1894–1902) from the slopes of just three individual peaks. It presumably replaces the similar Long-billed Partridge (R. longirostris) of the lowlands and may occupy mid-montane elevations throughout the central highlands. Only adult males are separable in the field and its vocalizations are unknown.
