The black grouse lives above 1200 m, and can only be found in the Alps. It is possible to spot the male due to its black plumage and its tail in the shape of a lyre (which is why its French name is Tétras Lyre). While it spends most of the time in winter in an igloo scooped out of the snow as protection against the cold, in the spring it performs spectacular parades to attract a female. The National park is tracking the population of the species in this zone.
