Distribution, diet and winter ecology of the Imperial Eagle Aquila heliaca in Jordan [PDF]

Vertebrate Zoology, 2012
The present study is the first attempt to investigate the diet, seasonality and distribution of the globally vulnerable Imperial Eagle Aquila heliaca in a wintering habitat in Jordan. There was a temporal pattern of observations, with nearly all observations in the northwestern part of the country occurring in late December or January.

Adopcia mláďaťa myšiaka hôrneho (Buteo buteo) orlom kráľovským (Aquila heliaca) [PDF]

Tichodroma, 2023
: Here we present a succesful adoption within a taxonomic family but across orders in birds of prey. From 1977 through 2021, we monitored the population of the Eastern Imperial Eagle ( Aquila heliaca , hereafter Imperial Eagle) on the territory of the ...

Annual report on surveillance for avian influenza in poultry and wild birds in Member States of the European Union in 2022. [PDF]

EFSA J, 2023
Abstract All European Union (EU) Member States (MSs) are required to implement surveillance for avian influenza (AI) in poultry and wild birds and (i) to notify the outbreaks, when relevant and (ii) to report the results to the responsible authority.

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 ...

Substitute nesting by Imperial Eagles (Aquila heliaca) in Slovakia [PDF]

Slovak Raptor Journal, 2012
Abstract During consistent monitoring of nesting pairs of Imperial Eagles primarily in Eastern Slovakia it was found that if for some reason the first clutch of eggs was destroyed at the very beginning of nesting, i.e. in late March or the first half of April, the eagles proceeded with substitute nesting.

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.

EFSA J, 2022
Abstract European Union (EU) Member States (MSs) are required to carry out surveillance for avian influenza (AI) in poultry and wild birds and notify the results to the responsible authority. In addition, Iceland, Norway, Switzerland and the United Kingdom (Northern Ireland) also implement ongoing surveillance programmes to monitor incursions of avian ...

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

Genetic structure of the Imperial Eagle (Aquila heliaca) population in Slovakia [PDF]

Slovak Raptor Journal, 2009
Genetic structure of the Imperial Eagle (Aquila heliaca) population in SlovakiaThe distribution of the Imperial Eagle (Aquila heliaca) in the Carpathian Basin is not continuous, since western and eastern breeding pairs are separated by 150 km from each other in Slovakia, and 70 km in Hungary.
