Description
The adult male is the most peacock-like member of the genus Polyplectron in appearance. It has an erectile crest and highly iridescent electric blue-violet, metallic green-turquoise dorsal plumage. It breast and ventral regions are dark black. The rectrices are wide, flat, and rigid. Their terminal edges are squared. Each tail plume and upper-tail covert is marked with highly iridescent, light reflective, ocelli. The tail is erected and expanded laterally together with the bodies of the birds. The male also raise one wing and lower the other, laterally compressing the body during pair-bonding, courtship displays as well and may also be antipredator adaptation. The female is slightly smaller than the male. Its contour plumage is cloudy silt in colouration. The mantle and breast are a dark sepia in coloration. The rectrices are essentially similar to those of the male, exhibiting marked adumbrations and stunning ocelli. Throughout, their plumage is earthen and difficult to distinguish from the substrate and branches. While it has similar proportions of the tail to the male, its markings are not as visually arresting. Like the male, the female has a short crest and is whitish on the throat, cheeks and eyebrows. Chicks are vivid ginger and cinnamon hued with prominent yellow markings. Juveniles of both sexes in the first year closely resemble their mothers. Subadult males in their second year more closely resemble their fathers but the mantle and wing coverts are marked with adumbrations analogous with the ocelli in the contour plumage of other peacock-pheasant species. Like other peacock-pheasants, Palawan males and some females exhibit multiple spurs on the metatarsus. These are used in anti-predator defense, foraging in leaf litter and contests with other males. The male Palawan excavates slight depressions in which it orients its body during postural display behaviors. The bird vibrates loudly via stridulation of rectrice quills. This communicative signal is both audible and as a form of seismic communication. Palawan peacock-pheasants are strong fliers. Their flight is swift, direct and sustained.

Feeding Habits
Palawan Peacock-pheasant predominantly consumes insects, fruits, and seeds. Exhibiting ground-foraging behaviors, it typically uses its feet to unearth food. This species has a preference for feeding in the underbrush, showing an adaptation to dense forest floors.
Habitat
The habitat of the palawan Peacock-pheasant encompasses primary and secondary forests situated in undulating territories. Traditionally associated with coastal lowland forests, a significant portion of which has been logged, the palawan Peacock-pheasant also inhabits dwarf forests dominated by Casuarina trees growing on serpentine rock. These birds are also found within disturbed forest margins extending up to montane regions, adapting to environments that include dense bamboo thickets of the genus Schizostachyum.

General Info
Behavior
Peacock-pheasants are highly invertivorous, taking isopods, earwigs, insect larvae, mollusks, centipedes and termites as well as small frogs, drupes, seeds and berries. They are strictly monogamous, renesting yearly. The female usually lays up to two eggs. Both parents rearing chicks for up to two years. Males act as sentinels of nest sites and are highly pugnacious during the reproductive cycle.
Distribution Area
Endemic to the Philippines, the Palawan peacock-pheasant is found in the humid forests of Palawan Island in the southern part of the Philippine archipelago.
Species Status
Due to ongoing habitat loss, small population size and limited range as well as 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.
