In addition to the small birds in the alpine meadows (the wheatear, the meadow pipit and the Eurasian skylark) the reserve is home to birds of prey including the royal eagle (2.20 m wingspan, brown plumage and round-edged tail) and the bearded vulture (2.80 m wingspan, beige to red body, black wings, light head, black diamond tail). The first comes to hunt marmots, mountain hares, foxes and chamois and ibex kids. The second is strictly a scavenger who mostly eats bones!
