This is Capra Ibex, a species of mountain goats that only lives in the European Alps.
Capra Ibex is regarded as a somewhat mystical animal. In local legends, they often possess supernatural powers.
They live high in the mountains, on steep rocky terrain, and are difficult to spot.
We saw a group of them once when hiking with my parents in the Slovenian Alps.
