The koklass (Pucrasia macrolopha) is a superspecies of Galliform, being closely related to progenitive grouse that lived during the Miocene. They are more distantly related to pheasants. Koklass are only species in the 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 galliforms 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 mont
