The Palawan Peacock-pheasant, Polyplectron napoleonis also known as Napoleon Peacock-pheasant is a medium-sized, up to 50cm long, bird in the family Phasianidae. It was long known as Polyplectron emphanum (Dickinson 2001).
The male is the handsomest and most peacock-like member of genus Polyplectron. It has an erectile crest, white stripe over eye, and highly iridescence metallic green and black plumage. The tail feathers are decorated with large blue-green ocelli, which may be spread fan-like in courtship display. The female is smaller than male. It has a dark brown plumage with short crest, and whitish on throat, cheeks and eyebrow.
A Philippines endemic, the Palawan Peacock-pheasant is distributed to humid forests of Palawan Island in the southern part of Philippines archipelago. The female usually lays up to two eggs.
The Palawan Peacock-pheasant with its unique male plumage and distant range represents a basal (Early? Pliocene, c.5-4 mya[2]) offshoot of the genus Polyplectron (Kimball et al. 2001).
Due to ongoing habitat loss, small population size, limited range and hunting and capture for trade, the Palawan Peacock-pheasant is classified as Vulnerable in the IUCN Red List of Threatened Species. It is listed on Appendix I of CITES.
