with small ocelli and long graduated tail feathers. Both sexes are similar. The male has metallic blue ocelli on upperparts, green ocelli on tail of twenty feathers and two spurs on legs. Female has black ocelli on upperparts, unspurred legs and tail of eighteen feathers. The female is smaller and duller than male. A shy and elusive bird, the mountain peacock-pheasant is distributed and

and grey peacock-pheasant (Kimball ''et al.'' 2001). The molecular data suggests - though not with high confidence - that this species diverged from mainland stock earlier than the bronze-tailed peacock-pheasant. This is quite spurious, since its biogeography and derived plumage, and the fact that it is a peninsular mountain endemic indicate it is derived from a fairly small
