Animals Sierra de Guadarrama

The Sierra of Guadarrama is biological reserve that is localizated in the middle of the Peninsula Iberica. There you can find many types of animals like:

  • Birds
  • Mamals
  • Fish
  • Amphibian
  • Reptile


In the Sierra de Guadarrama National Park and in its Peripheral Protection Zone there are 133 species of birds with regular presence during some time of the year, depending on the summer, wintering or permanent nature of the species in question.

Black vulture


It is the largest bird of Europe (with almost 3 meters from tip to tip of the wing). It stands out above the rest of raptors for its abundant presence in this space, being one of the species of the National Park that presents greater needs of conservation, given its situation of threat on a global scale.

Imperial Eagle

it is a large raptor, the adult is of general brown tone very dark, with whitish shoulders. It is one of the two endemic birds of the Iberian Peninsula that inhabit the National Park.


In the Sierra de Guadarrama National Park and in its Peripheral Protection Zone there are 58 species of mammals. The Mediterranean mountains like the Sierra de Guadarrama constitute important areas for the conservation of the diversity and wealth of species of fauna in general and of the mammals in particular.


It is a large carnivore, robust and adapted to the underground life. It reaches 80 cm in length and reaches a weight of 9 kg, with a little sexual dimorphism. Badgers are forest habitats where forests and grasslands alternate in moderately cool areas.

In the Sierra de Guadarrama National Park and in its Peripheral Protection Zone, 23 species of reptiles are inventoried, which gives an idea of the outstanding role played by the Sierra de Guadarrama in the conservation of this fauna group.  The abundance of individuals in certain taxa, along with the high number of endemisms, justify the outstanding value of these enclaves, not only in a regional but also national and European framework.

It is a medium-sized lizard with relatively robust limbs. The tail is long, practically twice the head-body length, presenting a succession of wide and narrow rings. It has a large and somewhat crushed, well defined head. The dorsal scales are somewhat larger than the sacks and the body is long and flattened.

Medium robust lizard with a maximum head and body length of 131 mm and intact tail 1.5 to 2 times the length of head and body. The adult males have the green dorsum finely dotted black and during the heat they acquire a very intense blue coloration in the head. The dorsum of adult females may be green or brown and usually have large black spots with white ocelli on the sides.
