Apparent Survival of Territorial Golden Eagles Using Non‐Invasive Genetic Profiling
In a novel study for the species, DNA was extracted from moulted feathers over 4 years involving 21% of the Scottish population of territorial golden eagles, and individuals' genetic profiles were analysed for apparent survival rates. Results showed sexual differences but not between two sub‐populations; very few cases of breeding dispersal were ...

Evaluating the demographic impacts of the highly pathogenic avian influenza panzootic
Our findings demonstrate that the HPAIV panzootic can cause rapid and long‐lasting impacts on the dynamics of long‐lived species. This raises major concerns for the conservation and long‐term viability of the many severely affected long‐lived species worldwide.

Our results demonstrate that to be effective in stimulating redistribution, an understanding of the drivers of site use is crucial for shooting‐based disturbance regimes. We emphasise the importance of providing refuges to encourage site use and highlight the importance of considering the spatio‐temporal coordination of shooting disturbance to ...

Successful stocking of wild European perch in a reestablished lake with lasting effect over 10 years
Biological manipulation of fish compositions to enhance top‐down control of trophic webs is a common method for improving water and ecological quality in shallow eutrophic lakes, but it often fails. As an alternative to manually thinning unfavored fish stocks, piscivorous fish species can be released to suppress the recruitment of cyprinid fish ...

In 2023, highly pathogenic avian influenza (HPAI) heavily affected gulls in Europe. In July, a mass mortality event was reported in the black‐legged kittiwake (Rissa tridactyla) breeding colony at Ekkerøy in Northern Norway. The cause was confirmed to be infection with the HPAI H5N1 clade 2.3.4.4b virus, genotype EA‐2022‐BB. We describe the outbreak in

Global analysis of threat status reveals higher extinction risk in tropical than in temperate bird sister species [PDF]
Given increasing pressures upon biodiversity, identification of species’ traits related to elevated extinction risk is useful for more efficient allocation of limited resources for nature conservation.

О взаимоотношениях скопы и орлана-белохвоста в Северной Беларуси
В свете событий последних десятилетий по увеличению численности орлана-белохво-ста (Haliaeetus albicilla) во многих европейских странах, естественно возник вопрос, а как поведёт себя в этих условиях скопа (Pandion haliaetus), населяющая, в основном ...
