Not sure what to do with this one? Is the Dulit Partridge a subspecies or a full species? I may want to check with our BirdForum guru on taxonomic classification, Richard Klim, and ask him what the current thought is on the "long-billed partridge(s)".
From Wikipedia on Dulit Partridge:
"It is found in the Malay Peninsula, Sumatra and Borneo. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist montane forests. It is threatened by habitat loss. There are two distinct subspecies; the nominate race R. l. longirostris is relatively widespread, while R. l. dulitensis, sometimes considered to be a full species known as the Dulit Partridge or Hose's Partridge (R. dulitensis), has a very restricted range in the mountains of central Borneo."
According to Avibase - the world bird database , this taxon is now split into:
Rhizothera longirostris and Rhizothera dulitensis

While it appears, from looking at Birdlife International, there are two distinct races, but not two species yet.
