Grouse ( Lyrurus ) are a species of bird from the family of pheasant-like (Phasianidae) used to order the chicken birds heard (Galliformes). The species occur exclusively in Eurasia . The Caucasian Black Grouse is native to the Caucasus . The black grouse , to which a total of six subspecies are assigned, occurs from western Europe to eastern Siberia and northern Mongolia . Occasionally the two species of this genus are the capercaillie and the stone owlplaced in the genus Tetrao . In more recent literature, however, they are usually assigned to a separate genus.
Similar to the capercaillie and stone owl, the Caucasian black grouse and the black grouse, which is common in the north of the Palearctic , have long, feathered legs but bare toes. The males have predominantly black body plumage and an elongated tail made of 18 feathers. The tail feathers of both species are shaped differently and, unlike the capercaillie and stone wall fowl, they share a common salt.
