That animal is a Chamois / Gemse. It is a goat-antelope type animal in Europe. It can climb the craziest terrain. A real trophy to hunt (often involves serious mountain climbing - no four wheeling or shooting off the hood!). They are specialized on herbs and picky eaters. I am sure that wall grows something they really like. Also, hanging out on the wall is safe (who's going to go after them?)
