Japanese Golden Eagle Conservation Science: Current Status and Future Needs (original) (raw)

Appennino umbro-marchigiano golden eagle breeding biology 1976-2016

A long-term study on a Golden Eagle population was carried out between 1979 and 2016 in a 5000 km 2 area of Central Italy. The number of pairs has grown from 10 to 18 in the last 25 years. Nevertheless, the whole population density doesn't reach the ones in the Alps. The growth of the population is probably due to the higher percentage of protected areas and higher amounts of wild ungulates and live prey species.

Conservation measures undertaken to improve the population status of eastern imperial eagle (Aquila heliaca) in Bulgaria

Slovak Raptor Journal, 2014

This study presents the results of conservation measures undertaken and their impact on the eastern imperial eagle population in Bulgaria. The species is distributed in the south-eastern part of the country, as there is only one known pair in central Bulgaria. During the period 2009-201 3, 28 different breeding territories were occupied. The population increased by 20%, as the number of pairs that occupied breeding territories increased from 20 in 2009 to 24 in 201 3. In general, the mean values of the breeding parameters of the eastern imperial eagle population for the period 2009-201 3 were as follows: productivity (P) 1 .03±0.1 8; breeding success (BS) 1 .1 8±0.21 ; and fledgling success (FS) 1 .68±0.1 6. The annual survival rate of breeders varied from 0.795 to 0.932. The most important factor causing the mortality of immature eagles was electrocution. Shooting and poisoning have become important mortality factors, too. Guarded pairs had a higher mean breeding success (1 .32±0.8...
