As a result of hunting and logging, the deer had all but disappeared from the Savoy forests. Reintroduced between 1958 and 1973, it has adapted remarkably well to the mountain environment to form a fine population. In autumn the mating season gives rise to spectacular fighting between males, but it is the raucous and powerful cries of the deer that bring the valley to life. Taking advantage of the peacefulness of the place, the animals bellow practically all day long.
