Ponds
The arid scarp above the ponds is an ideal habitat for many reptiles: common wall lizards (Podarcis muralis) and grass snakes (both ring snakes - Natrix natrix - and dice snakes - Natrix tessellata) find shelter between rocks or either warm themselves on the stones near the banks. In the aquatic vegetation we can see some dragonflies and some butterflies that in our continent are at risk of extinction like the jersey tiger (Euplagia quadripunctata) and the false ringlet (Coenonympha oedippus).
The abundance of insects attracts a lot of birds: common house martins (Delichon urbicum) and Eurasian crag martins (Ptyonoprogne rupestris) go up from the valley floor and reach the overhanging cliffs in order to feed themselves and build their nest. In the crevices of these rocky walls, two skilful predators try to hide themselves: the peregrine falcon (Falco peregrinus) and the Eurasian eagle-owl (Bubo bubo), the biggest nocturnal raptor in Europe.
