Sex-Biased and Density-Dependent Natal Dispersal in a Highly Mobile but Philopatric Raptor. [PDF]

Ecol Evol
High philopatry, female‐biased natal dispersal distances, and density‐dependent dispersal patterns (with both conspecific attraction and competition avoidance) were found in the eastern imperial eagle. The study was conducted on the natal dispersal data obtained from 116 birds between 2011 and 2024 in the Pannonian region, using the combination of ...

Moderate evidence for the sex-dependent effect of poisoning on adult survival in a long-lived raptor species. [PDF]

Ecol Evol
Survival estimation of adult imperial eagles revealed that poisoning activity may have a stronger negative effect on the survival of the smaller‐bodied, more actively foraging males than on females. The genetic‐based mark‐recapture analysis was conducted on data of over 600 birds breeding in Hungary between 2011 and 2022.

A LEAP Forward in Wildlife Conservation: A Standardized Framework to Determine Mortality Causes in Large GPS-Tagged Birds. [PDF]

Ecol Evol
A novel framework for determining the causes of mortality of large GPS‐tagged birds, the LIFE EUROKITE Assessment Protocol (LEAP), was developed. LEAP integrates GPS tracking data, site investigation, and necropsy to derive mortality causes and a corresponding certainty score. Two case studies demonstrated improvements in mortality assessments compared
