More than half of all amphibians, reptiles, birds and mammals that occur in Austria are found in the Hohe Tauern National Park. The ibex, chamois, marmot, golden eagle and bearded vulture are considered the Big Five in the Hohe Tauern National Park.
The ibex, one of the most imposing mammals of the Hohe Tauern, is one of the true goats and can therefore successfully mate with the domestic goat. With its stocky, muscular build, it reaches a head trunk length of 150 cm and a shoulder height of 90 cm. The does weigh about 45 kg, whereas bucks can weigh over 100 kg. The buck has powerful, backward-curved horns up to 1 m long, while the doe has only short, barely curved horns. Thanks to their deeply split hooves with rubbery toe pads, ibexes are good climbers and jumpers. The females with the young and the bucks live in separate herds. Only the old bucks become loners.
