Koklass Pheasant

The koklass pheasant (Pucrasia macrolopha) is a species of gamebird, being closely related to progenitive grouse that lived during the Miocene. They are distantly related to pheasants and are most closely related to grouse and turkeys. Koklass are the only species in the monotypic genus Pucrasia. Both the words koklass and pucrasia have been onomatopœically derived from the bird's territorial call.

Koklass are boreal adapted species which separate into three distinct species groups. They are one of the few gamebirds that regularly fly uphill and are capable of sustained flights of many miles. They are monogamous with a slight tendency toward social polyandry. Both parents rear the chicks. Koklass are largely vegetarian for much of the year consuming pine nuts, pine shoots, bamboo shoots and seeds. They are highly insectivorous during the warmer months that coincide with nesting and chick-rearing. During this phase of their life cycle they live almost exclusively on ants but also are documented consuming catkins, pollen and fruit.
