The black grouse (tetrao tetris or lyrurus tetris) is a mountain bird in the family tetraonidae.
General informations Edit
It lives in mountain meadows and rocky areas, feeding on vegetables and seeds. The all-black males have distinctive red wattle over the eye and show a striking white stripe along each wing in flight. They have a lyre-shaped tail which is fanned out and raised to show white under-tail feathers when displaying. The smaller grey-brown females have a slightly notched tail. Habitat loss and overgrazing have resulted in severe population declines which make this a Red List species. Positive habitat management is helping them to increase in some areas.
