Rhizothera dulitensis
The Dulit Partridge (Rhizothera dulitensis), often considered a subspecies of the more widespread Long-billed Partridge, is an exceptionally elusive and poorly known gamebird endemic to the montane forests of Borneo.

Males typically boast a chestnut head and breast, a grey belly, and heavily barred flanks, contrasting with a dark bro...
This secretive gamebird inhabits dense, primary montane rainforests, typically found at elevations ranging from 900 to 1,600 meters above sea level.
Its diet primarily consists of insects and other invertebrates, along with a variety of plant material such as seeds, tubers, and fallen fruits, foraged by probing and scratching the forest floor.

Historical records and recent detections largely stem from the mountainous interiors, parti...
