Taxonomy
The genus Tetrao was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae.[1] The genus name is the Latin word for a game bird, probably a black grouse.[2] The black grouse was included by Linnaeus in the genus Tetrao but is now placed in the genus Lyrurus.[1][3] The type species was designated as the western capercaillie (Tetrao urogallus) by George Robert Gray in 1840.[4][5]
