White-necklaced Partridge (Arborophila gingica)
Arborophila is a genus of partridges in the Phasianidae family. The genus has the second most members within the Galliformes after Francolinus although Arborophila species vary very little in bodily proportions with different species varying only in coloration/patterning and overall size. These are fairly small, often brightly marked partridges found in forests of eastern and southern Asia. Some species in this genus have small ranges, and are threatened by habitat loss and hunting.
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: Arborophila orientalis–sumatrana–campbelli–rolli complex, Arborophila cambodiana complex, and Arborophila chloropus–merlini–charltonii complex. Arborophila 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).
