The other subspecies include the Hainan Grey P. b. katsumatae found only on the island of Hainan, the Ghigi's Grey P. b. ghigii native to south-eastern China and the Lowe's Grey P. b. bailyi whose range is not well known, but believed to be native to western Assam. Variation in the subspecies is distinct, but it is tough to know which subspecies are currently being reared in American aviaries. The smallest of the subspecies, and most distinct, is katsumatae which is much darker in overall plumage and the markings brighter. I would to like hear from breeders who have been able to breed true lines. This species can be distingushed from other Polyplectron species by the overall grayish brown plumage that is finely mottled with drak gray, white and buff.
Males have metallic bluish-green ocelli on the wings and mantle.
Each tail feather is marked with two large metallic green, with a tint of purple, ocelli. The cheeks and throat are white and he has a gray upright crest that leans forward in courtship displays. The female is much smaller and duller than the male. The ocelli is not near as bright or large as well. The breeding season begins in March and may last until July.
