The large number of caves and holes in slopes right on the coast are an ideal habitat for breeding pairs of European shags. They occupy the nest in January and cover it with a range of plant materials, including sea weed. Their feathers are not waterproof and so they can often be seen perched on the rocks with their wings spread out in the sun. It is very common in the winter when individuals come from central Europe.
Shags are fishing birds which feed exclusively on the fish they catch, diving to depths of up to 30 metres often in areas connected to meadows of Posidonia oceanica.
