This work is divided into three parts: a first block consists of a revision and updating of the status, tendencies and problems of avian scavengers (griffon, Egyptian and bearded vultures) in the mountains of the northern Iberian Peninsula, from the Basque Country to Catalonia. Subsequently, there is a diagnostic of the situation of the countries in the Mediterranean Basin in Europe that still have populations of these avian scavengers. The aim of these chapters is to bring existing knowledge of the population dynamics of these birds and their associated conservation problems up-to-date, above all in light of the crisis of food availability caused by the regulations and restrictions placed by the European Union on the management of these birds’ trophic resources. In the second part aspects relating to the ecology and management of feeding stations are tackled from a perspective of conservation biology. The ecological impact on soils and higher trophic levels of the sudden appearance of large carcasses in the wild are examined, along with the effects resulting from the distribution, abundance and variability in space and time of these trophic resources. New management strategies involving the concentration of recourses in just a few feeding stations are closely examined and the pros and cons of such strategies for birds, as well as for the structure and functioning of avian scavenger guilds and other vertebrate communities are also discussed. The third and final part of this monograph investigates the clash between griffon vultures and farmers, and aims to provide a diagnosis of the seriousness of the biological and ecological problem that this conflict represents. The aim here is to clarify the situation by separating the wheat from the chaff in order to facilitate decision-making untainted by any visceral beliefs or opinions.
