Black Grouse The Black Grouse (Tetrao tetrix) is a large bird in the grouse family. It is a sedentary species, breeding across northern Eurasia in moorland and bogs with some trees. The Black Grouse is closely related to the Caucasian Black Grouse. These birds have a group display or lek in early spring. As with many Gamebirds, the male is larger than the female at 49-55 cm compared to her 40-45 cm length. The cock is very distinctive, with black plumage, apart from red eyebrows and a white wingbar, and a lyre-shaped tail, which appears forked in flight. His song is loud, bubbling and somewhat dove-like. The female is greyish-brown and has a cackling call. She takes all responsibility for nesting and caring for the chicks, as is typical with gamebirds. This species is declining in western Europe due to loss of habitat.
