Black grouse (Lyrurus tetrix; Ukrainian: teterev). A bird of the Galliformes order and Tetraonidae family. The average weight is 1.7 kg for the male and 1.3 kg for the female; the average length is 60 cm. It is commonly found in the forest belt and forest-steppe belt of Europe and Asia.

The black grouse is a valuable commercial bird.
