The Natural Park has an immense diversity of animals, of which birds occupy a large proportion. The most common are birds of prey, with permanent residents such as Bonnelli’s eagle and the golden eagle, the peregrine falcon, the common kestrel, the Eurasian Eagle Owl, and the goshawk. The short-toed eagle and the booted eagle can be spotted during migration periods.
Sea and other aquatic birds are also of particular note, due to proximity to the Mediterranean Sea and the inland reservoirs and rivers. These include various members of the gull family, cormorants, coots, ducks, plovers and dippers. Within the woodland and mountain areas, the variety is just as impressive: woodpeckers, nightingales, rock buntings, rock and blue rock thrushes, crag martins and alpine accentors.
In and around the streams and rivers, amphibians abound: salamanders, newts, toads and frogs, as do reptiles in the rocks and lower latitudes: chameleons, lizards, and at least 4 species of land snake (very difficult to come across!).
The best known of the mammals in the Natural Park is the mountain goat. Once under threat of extinction, its recent protection has led to an increase in numbers to around 2,000 , one of the biggest populations of its type in Spain. Additionally, there are several pairs of deer, red and grey squirrels, various species of bat, and the wild cat.
