Assessment InformationYear published: 2015Date assessed: 2015-03-31Assessor(s): BirdLife InternationalReviewer(s): Symes, A.Compiler(s): Ashpole, J., Burfield, I., Ieronymidou, C., Pople, R., Wheatley, H. & Wright, L.Assessment RationaleEuropean regional assessment: Least Concern (LC)EU27 regional assessment: Least Concern (LC)

In Europe this species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern in Europe.

Within the EU27 this species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern in the EU27.

Habitats and EcologySome birds are migratory, overwintering in Africa, although many others are resident or nomadic (Orta et al. 2015). It relies heavily on soaring flight, and has been shown to fly at altitudes of 10,000 m and higher. Birds hunt alone but congregate at food sources and roosts; they also tend to migrate singly, but concentrations (usually up to 15 individuals) form at sea crossings and strong thermals (Ferguson-Lees and Christie 2001, Orta et al. 2015).

exclusively on carrion, mainly that of large mammals. The nest is usually built on a rocky outcrop, with sheltered ledges or small caves preferred and it is a thin, fairly small platform of branches, sometimes stolen from other large raptors. A single egg is laid (Orta et al. 2015).Habitats & Altitude

Habitat (level 1 - level 2) Importance OccurrenceGrassland - Temperate suitable breedingGrassland - Temperate suitable non-breedingRocky areas (eg. inland cliffs, mountain peaks) major breedingShrubland - Mediterranean-type Shrubby Vegetation suitable breedingShrubland - Mediterranean-type Shrubby Vegetation suitable non-breedingAltitude 0-2000 m Occasional altitudinal limits

ThreatsIt declined markedly throughout the 19th–20th centuries in much of Europe, mainly due to direct persecution and "bycatch" from the poisoned carcasses set for livestock predators (Snow and Perrins 1998, Ferguson-Lees and Christie 2001, Orta et al. 2015). In some areas a reduction in available food supplies, arising from changes in livestock management practices, also had an impact (Ferguson-Lees and Christie 2001, Orta et al. 2015). It is very highly vulnerable to the effects of potential wind energy development (Strix 2012).Threats & Impacts

ConservationConservation Actions UnderwayEU Birds Directive Annex I. CMS Appendix II. CITES Appendix II. Five successful reintroductions have occurred in France (Global Raptor Information Network 2015) including in 1981 in the Massif Central as well as in Drôme and Provence (Orta et al. 2015). Additional reintroduction projects have led to the establishment of colonies in Italy, Spain and Austria. During the 1980s, in Serbia, the species benefited from winter feeding stations (Global Raptor Information Network 2015). Increases in recent decades have also been due to the banning of poisoning of carcasses (Le Gouar et al. 2008). European laws prohibiting farmers from leaving dead animals on their land have also been rescinded, benefiting this species (Global Raptor Information Network 2015).

Conservation Actions ProposedNon-intensive livestock management systems, such as pastoralism, should be maintained and promoted to ensure a food supply for this species; the provision of feeding stations is also beneficial, particularly when food is scarce. Large and continuous areas of afforestation should be avoided to maintain the large areas of habitat needed for foraging (Tucker and Heath 1994). The ban on poisoned carcasses should be enforced and the leaving of dead animals encouraged.
