The Caucasian grouse is a sedentary species, breeding in the Caucasus and Pontic Mountains of northeast Turkey on open slopes with low Rhododendron or other scrubs but in proximity to deciduous broad-leaf forest. These bird have a group display or lek in May and June. Unlike the male Eurasian black grouse, the Caucasian grouse display is almost mute but for a thin whistling of the cock fluttering his wings as he leaps and turns in the air, producing a flash of white as the underwing feathers are briefly revealed. The hen lays up to ten eggs in a ground scrape and takes all responsibility for nesting and caring for the chicks, as is typical with gamebirds.
