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.
