Tetrao is a genus of birds in the grouse subfamily known as capercaillies[needs IPA]. They are some of the largest living grouse and can be found in the forested areas of the Eurasian Palearctic.
Feathers from the bird were used to decorate the characteristic hat of the bersaglieri, an Italian ace infantry formation.
Taxonomy
The genus Tetrao was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. The genus name is the Latin word for a game bird, probably a black grouse. The black grouse was included by Linnaeus in the genus Tetrao but is now placed in the genus Lyrurus. The type species was designated as the western capercaillie (Tetrao urogallus) by George Robert Gray in 1840.
