They turn in all directions, move ahead or jump, while making a characteristic sound called bubbling.
It is in May that the peak of Black Grouse mating season falls. It is worth going to their surroundings very early, because males begin their mating rituals before dawn.
Until the end of May, due to the protection of black grouse, some trails are closed, e.g. green trail from Polana by Morena Kotla Wielkiego Staw to the dorsal red trail. There is however a yellow trail, starting in the same place, and leading to the top by Pielgrzymy and Sunflower, rock groups, from which there is a beautiful panorama. Obligatory places to see in Karkonosze.
