Arborophila
Arborophila is a bird genus in the family Phasianidae. The genus has the second most members within the Galliformes after "Pternistis", although "Arborophila" species vary very little in bodily proportions with different species varying only in colouration/patterning and overall size. These are fairly small, often brightly marked partridges found in forest of eastern and southern Asia. Some species in this genus have small ranges, and are threatened by habitat loss and hunting. Species. While most species in this genus are highly distinctive and their taxonomic treatment is settled, there are three complexes where the species limits have not  been entirely resolved and to various degrees are disputed: "A. orientalis–sumatrana–campbelli–rolli" complex, "A. cambodiana" complex, and "A. chloropus–merlini–charltonii" complex. "A. torqueola" is always called the hill partridge or common hill-partridge, but in all other species "hill" is often disregarded (for example, "A. rufipectus" is variously known as the Sichuan hill-partridge or Sichuan partridge).
