To observe black grouse in summer, you need to get up early. In France, black grouse (or blackcocks) can only be found in the Alps. In spring, the male with its black plumage and lyre-shaped tail with white under-tails parades to attract females. In winter, they spend most of their time in igloos dug out of the snow to protect themselves from the cold. This is a particularly sensitive period because they cannot replenish the energy used up when they must leave their igloos suddenly if an off-piste skier or show-shoe hiker passes by.
