he fauna of the Peña is a faithful reflection of what occurs with its flora: an interesting and varied contingent of species of mammals, birds and invertebrates populate this varied mosaic of habitats: woods, groves, rocky walls, meadows, crops.

   The rocky escarpments act as a refuge for one of the most emblematic species of the Pyrenees: the bearded vulture. This large vulture, together with the griffon vulture, take advantage of the warm (thermal) air currents close to the calcareous walls to make their displacements. The golden eagle, the peregrine falcon, the wallcreeper and a long etcetera can be found in these places.

   The holm oak and gall oak woods house birds such as the wood pigeon, the grey-necked nightjar, the blue woodcreeper and birds of prey such as the goshawk, the booted eagle and the short-toed eagle Among the mammals we can highlight the garden dormouse, the genet, the badger and the wild boar. In the woods of the shade of the Peña other ornithological rarities live: we are talking about the magnificent grouse and the cryptic tengmalm’s owl.

   Close to the fields and villages, in this peculiar environment, modelled more intensely by man, such attractive birds as the European bee-eater or curious ones such as the woodchat shrike can be found. Birds of prey such as the common buzzard or the red kite fly over these fields in search of prey. Many of the wood mammals make night incursions into this habitat to supplement their forest diet.
