We may point out the presence of Chiroptera (Pipistrellus sp.) in the diet of Falco peregrinus and Crustacea (Nephrops norvegicus) in F. tinnunculus, the last one being a product of garbage disposal areas; in all the rest, the feeding patterns are similar to the ones found in the rest of Iberia. The problems of preservation of Raptors have no doubt reached their critical point, due to the great quantities of them that are captured, to the destruction of their nests and environment, and to the poisoning they are suffering through phytosanitary products.
