Black grouse current. Not just mating games, but a sacred ritual inherited from the depths of time. The forest thicket. Lawn. The first rays of the sun. And in the silence, strange sounds are suddenly heard: a dull murmur... sharp clicks... a hissing chuff...These black beauties entered the arena. With scarlet eyebrows. With lyre tails. Ready to fight for the right to continue the family. A real wildlife show, during which grouse dance, fight, and seduce. It seems that spring itself speaks through their voices. RTG's film tells the story of these amazing sedentary birds and their celebration of spring.
