Bearded Vultures in northwest Europe Christopher McInerny and Andy Stoddart, on behalf of BOURC and BBRC Abstract Over the last 25 years more than 70 Bearded Vultures Gypaetus barbatus have been seen across northwest Europe, many far from their mountain breeding ranges in the Alps and the Pyrenees. It is highly likely that all such extralimital Bearded Vultures originate from reintroduced Alpine populations, which are increasing but not yet considered self-sustaining, rather than from natural populations in the Pyrenees or elsewhere. The species has been placed in Category E (and therefore not part of national bird lists) in all northwest European countries where birds have been seen, apart from Norway where one record is in Category D. This article explains the background to these decisions. World and European range and The Alpine population of Bearded taxonomy Vultures declined substantially during the Bearded Vultures Gypaetus barbatus are nineteenth and twentieth centuries as a result restricted to mountainous regions of the of human persecution, and finally became Palearctic and Africa (del Hoyo et al. 1994; extinct (Mingozzi & Estève 1997; SPB 2018).

European distribution of Bearded Vultures Gypaetus barbatus, illustrating the breeding range of natural populations in the Pyrenees (orange) and reintroduced populations in Andalusia, the Cantabrian Mountains and the Alps (green). Extralimital records of wandering birds from the Alpine reintroduction programmes are indicated, either as marked individuals (tags or bleached feathers; white) or unmarked individuals (black). Not all locations for wandering individuals are shown and the records are not exhaustive, but are mapped to illustrate the large numbers and wide distribution of extralimital birds that have been seen in northwest Europe.
