The Mountain Peacock-Pheasant (Polyplectron inopinatum) is found only in the montane forests of Peninsular Malaysia, making it one of the country’s most restricted-range birds. Unlike its more widespread relatives, it is entirely confined to cool, high-elevation habitats.

A remarkable fact about this species is that it was unknown to science until 1903 — its Latin name inopinatum literally means “unexpected.” Despite belonging to the peacock-pheasant group, it lacks the long extravagant tails of lowland relatives, instead showing shorter, rounded tail feathers decorated with iridescent eye-spots.

The species is monogamous, with males performing courtship displays that involve fanning their tail and wings to reveal the metallic eyespots. Both parents share responsibilities, but the female does most of the incubation.

Because of its restricted range and continuing habitat loss from deforestation, the Mountain Peacock-Pheasant is listed as Endangered. Its survival depends heavily on the conservation of Malaysia’s upland forests, which are also critical for many other endemic species.
