Animals
The animal that today is the pride of the park is the bearded vulture. After its extinction in 1986, its return to these mountains is the result of an ambitious and complex reintroduction project. Its elegant silhouette next to the wildest cliffs is the best proof that the human being adds, can correct the course and return to live in harmony with the rest of nature, and reintroduce itself in the south of Spain, this park playing the role breeding nucleus and released in freedom, for the whole of the Autonomous Community of Andalusia, and beyond. That dream is possible in the Sierras de Cazorla, Segura and Las Villas. When you come, you will check.
Large mammals
The Sierras de Cazorla, Segura y Las Villas Natural Park owes a large part of popularity to the fact that it is one of the easiest places to observe large wild mammals in their native environment.
Visitors can frequently spot mountain goats (Capra pyrenaica ssp. hispanica) in craggy areas and mouflon (Ovis musimon) on barren, rocky slopes. Herds of fallow (Dama dama) and red deer (Cervus elaphus) are very abundant in the pine forests and at the start of autumn the rutting and bellowing of the large stags is an unforgettable experience.
The wild boar (Sus scrofa) is another common species in the park, even becoming a familiar sight around tourist accommodation when food is left within its reach.
Birds of Prey
The great number of birds of prey that soar above these mountains is further evidence of the sound environmental health of the park, and no fewer than 23 of the 24 diurnal species native to the Iberian Peninsula can be observed here. Of these 23 species, 15 reproduce within the park.
We are rightly proud of the park's populations of golden eagles (Aquila chrisaetos) and peregrine falcons (Falco peregrinus), the fastest animal on the planet: the park is home to more than 20 breeding pairs of both species. Less common is the Egyptian vulture (Neophron percnopterus), which has been declared at risk of extinction in Andalusia. With more than 500 breeding pairs in the park, the griffon vulture (Gyps fulvus) is far easier to spot, while nothing is more exciting than catching a glimpse of the imposing silhouette of the bearded vulture (Gypaetus barbatus), which are being reintroduced into the park.
Each spring, short-toed snake eagles (Circaetus gallicus) and booted eagles (Hieraaetus pennatus) migrate over from Africa with clockwork precision to nest in the park's forests, where they compete for food with resident species such as the northern goshawk (Accipiter gentilis) and Eurasian sparrowhawk (Accipiter nisus).
Night-time also brings its fair share of winged predators: six of the seven species of nocturnal birds of prey native to the Iberian Peninsula inhabit the park, including the majestic eagle-owl (Bubo bubo), whose deep hoots can still be heard echoing through the undergrowth. A much more common sound in the forests is the call of the tawny owl (Strix aluco), while the scops owl (Otus scops) can be heard in almost all the towns and villages of the park.
Reptiles
The Spanish algyroides (Algyroides marchi) is one of the park's most symbolic animals, as it is only found in these mountains. It was discovered here in 1958 by the biologist José Antonio Valverde (from which the lizard's Spanish name, lagartija de Valverde, or "Valverde's lizard", is derived), who was one of the driving forces behind the creation of the Doñana National Park and who made the international scientific community aware of the existence of the bearded vulture in these mountains in the mid-20th century. The Spanish algyroides is dark green in colour and lives in only a few areas, always shady, grassy and near water.
The park is home to 21 species of reptiles, of which the most interesting are Bedriaga's skink (Chalcides bedriagai) and the three-toed skink (Chalcides chalcides): these are notable for the extraordinarily small dimensions of their feet, which are so small that they slither across the ground like snakes. The Iberian wall lizard (Podarcis hispanica) and large psammodromus (Psammodromus algirus) are extremely abundant and it is also easy to spot the boldly patterned ocellated lizard (Lacerta lepida), which likes to sit on rocks and absorb the sunshine. In more watery environments, the viperine water snake (Natrix Maura) is a common sight and often plays dead when it feels it is being watched, while the gentle Caspian turtle (Mauremys caspica) can also be spotted.
Fish
The cold, transparent, fast-moving waters of the high reaches of the park provide an ideal habitat for another of the park's most celebrated residents: the brown trout (Salmo trutta), which was declared at risk of extinction in Andalusia and which can only be caught in certain designated areas by catch-and-release fishermen who have a valid fishing licence and the corresponding permit.
The Andalusian barbel (Barbus sclateri) and nase (Chondostroma willkommii) prefer the middle to lower reaches of the park's rivers and can also be found in the Tronco and Anchuricas reservoirs. Certain species of chub, Squalius pyrenaicus, along with dace (Leuciscus alburnoides) and loach (Cobitis paludica) are also present in our rivers, as are a number of introduced foreign species such as the rainbow trout (Oncorhynchus mykiss) and black bass (Micropterus salmoides).
