Since the brown bear disappeared from these forests, red deer are the largest mammal in this region. This imposing animal boasts impressive antlers and adapts well to the conditions at this altitude. After becoming virtually extinct in Switzerland around 1850, it now populates a large part of the mountain forests once again.Does are usually found in herds with the fawns and the previous year’s young animals. Red deer bucks live in male herds except during the rutting season. The male animal’s antlers are designed to impress and for combat. Red deer have antlers from the age of two until the end of their lives.
