The koklass pheasant 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.

Galliformes is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl. Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds.
