The koklass pheasant (Pucrasia macrolopha) is a species of gamebird, being closely related to progenitive grouse that lived during the Miocene.

With exception of the subspecies P. m. nipalensis, P. m. castanea and P. m. macrolopha, which are endemic to the southern side of northwest and western Himalaya, the other five are confined to China and Mongolia.

The koklass pheasant is a medium-sized elusive bird confined to high altitude forests from Afghanistan to central Nepal, and in northeastern Tibet to northern and eastern China.

Upper parts of male koklass pheasant are covered with silver-grey plumage streaked velvety-black down the centre of each feather, and it has the unique feature of a black head, chestnut breast and prominent white patches on the sides of neck.

Though they skulk under bushes, which makes direct sighting difficult, they give loud chorus/predawn calls during the breeding season and during autumn, revealing their presence and allowing the populations to be estimated.
