SummaryPopulation estimates (number of breeding pairs) of Golden Eagles Aquila chrysaetos are given for most countries in Europe based on recent published accounts. Where published data are not available information is from local raptor specialists. The “best estimate” of the contemporary European population is 5,600 pairs ± 5%. The largest numbers are in Spain (c. 1,200 pairs) with Norway, European Russia, Scotland and Sweden each holding over 300 pairs. Information on trends reveals that most substantial populations (> 200 pairs) are stable; decreases are reported from some Baltic countries and in parts of southeast Europe. The total population is also shown for five biogeographic regions across Europe. In some cases, such “regions” may be more appropriate for the formulation of conservation priorities and policies than are the biologically artificial units defined by national boundaries.Des estimations des populations (nombre de couples nicheurs) d'Aigles royaux basées sur des publications récentes sont présentées pour la plupart des pays d'Europe. Là où les publications font défaut, des informations ont été requises apurès de spécialistes locaux. La population européene actuelle est estimée à 5,600 couples ± 5%. Les populations les plus fortes, soit plus de 300 couples, se trouvent en Espagne (env. 1,200 couples), Norvege, Russie européene, Ecosse et Suède. Les informations sur les tendances des fluctuations indiquent que la plupart des grandes populations (plus de 200 couples) sont stables; un déclin a été constaté chez certaines populations de l'est de la Baltique et du sudest de l'Europe. La population totale est aussi indiquée pour cinq régions biogéographiques qui peuvent s'avérer plus adéquates que les pays avec leurs frontières artifi-cielles pour la formulation de priorités et d'une politique pour la conservation de l'espèce.

Sixteen occupied nesting territories of Golden Eagle Aquila chrysaetos were studied between 2000 and 2020, in the southern part of the valley of Valdres, southeast Norway. Most of the study area consists of rolling hills dominated by spruce Picea abies with numerous clear-cuts. It was concluded that at least six (about 40%) of the eagle pairs in these territories move back and forth between two alternate, distant nesting areas 5.3 km apart (average). In two additional pairs, a second nesting area was considered possible. In the remaining eight, only one nesting area was found. The periods of one nesting area in use varied from 2–19 years, before moving to the other nesting area. This result was supported by panoramic mid-day surveillance of the air space between the two nesting areas during 2014–2020. The maintenance of a second core nesting area is most likely a strategy for moving to a more favourable hunting area and might be initiated by a new mate in the pair. The move might also be influenced by avoidance of a close neighbouring pair. A switch of nesting areas, as indicated by this study, could significantly affect results, when the number of eagle pairs in a certain area is counted.   Cover photo: Golden eagle.
