The Black Grouse (Lyrurus tetrix) is a large species of grouse found across northern and central Eurasia. It inhabits open moorlands, heath, and woodlands.

During the breeding season, male Black Grouse gather at traditional communal display grounds called leks, usually on open ground such as moorland, forest clearings, or meadows. Early each morning males arrive at the lek to call and display, fanning their lyre-shaped tails, puffing out their white undertail coverts, inflating the red wattles above the eyes, and strutting, bowing, and jumping as they spar with rivals to establish territories within the lek.

What does a Black Grouse sound like? At the lek, males produce distinctive bubbling, dove-like cooing sounds. These rapid, rolling series of soft notes carry long distances. This continuous cooing is punctuated by sharp, explosive hissing and sneezing calls, given as a male lunges or spars with a rival. They also make comical gargling sounds and soft grunts. Female Black Grouse make short clucking calls when brooding chicks as well as guttural alarm calls.
