Sabah partridge
The Sabah partridge (Tropicoperdix graydoni) is a bird species in the family Phasianidae. It is found in Borneo. It was formerly considered conspecific with the chestnut-necklaced partridge (T. charltonii), but can be distinguished by the buff scaling on the belly and the lack of rufous on the head. References
