In terms of wildlife, we could highlight the Sarrio, the bearded vulture or the brown alpine cow.

One of the most famous of these is the Sarrio, whose eyesight, sense of smell and hearing are excellent. It is not an endangered species and hunting is permitted. Another of the great protagonists of our landscapes is the marmot. It is important to know that the marmot lived in the Pyrenees but disappeared approximately 15,000 years ago, they were introduced back into the Pyrenees around the 1950's. They live in rocky areas and it is easy to recognise their presence thanks to their whistling.

But in addition to the above, thanks to the magnificent nature of this area we find many other mammals of interest such as the common squirrel, the deer, the hare, the roe deer, the fox, the genet, the wild boar, the common weasel, the European otter, the brown bear or the badger.

As for the most common birds, we find the vulture, which cleans the mountains of carrion and can weigh between 6 and 8 kilos. Nor can the bearded vulture, the only bird that feeds on bones, be missing in our landscape, being at the bottom of the food chain.

But our environment is not only inhabited by these two great birds of prey, but also by many other birds such as the common quail, the dipper, the red-legged partridge, the great spotted woodpecker, the snowy sparrow, the European turtle dove or several species of coal tit, as well as other birds of prey such as the Egyptian vulture, the eagle owl, the short-toed eagle, the peregrine falcon, the griffon vulture or the red kite.

Finally, we should also mention the wallcreeper, which gives its name to the popular cycling race held every year in the Val de Tena.

We can also find a wide variety of amphibians, including the Pyrenean newt, which is endemic to these mountains and is protected, as well as the aforementioned amphibian, others such as the red-legged frog, the Pyrenean frog, the common salamander, the common midwife toad and the webbed newt.

On the other hand, there are herds of the Alpine Brown Cow and, to a lesser extent, the Tensina Churra Sheep.
