Apparent Survival of Territorial Golden Eagles Using Non-Invasive Genetic Profiling. [PDF]

Ecol Evol
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 ...

Mitochondrial Genome Analysis of Philippine Eagles (<i>Pithecophaga jefferyi</i> Ogilvie-Grant 1896) From the Greater Mindanao Faunal Region. [PDF]

Ecol Evol
Mitogenome sequencing is a promising alternative for the genetic studies of animals. In this work, we examined the genetic diversity of the critically endangered and endemic Philippine eagles and their evolutionary relationship to other birds of prey.

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing. [PDF]

Zoo Biol
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

Prevalence and Genetic Diversity of Haemoproteus and Leucocytozoon in Raptors and Other Captive Birds at the National Zoological Garden in South Africa. [PDF]

Integr Zool
Captive birds at the National Zoological Garden in South Africa harbor diverse haemosporidian parasite species and lineages. This might compromise conservation efforts of threatened species. ABSTRACT Avian haemosporidian infections have been associated with disease outbreaks in zoos and rehabilitation centers globally. This study aimed to determine the

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

Eagle Nesting Groups in the Important Bird Area “Donyz-Tau cliff faces” in 2022

Пернатые хищники и их охрана, 2023
The Important Bird Area (IBA) “Donyz-Tau cliff faces” (KZ019), with an area of 387,110 hectares, has been allocated by I.V. Karyakin (2008) based on survey results in 2003–2006. Survey showed several globally threatened and biome-specific species nesting

Steppe Eagle Population Structure Genetic Study: is There Hope for the Endangered Species?

Пернатые хищники и их охрана, 2023
For centuries, Steppe Eagle (Aquila nipalensis) had been the most numerous Palearctic Aquila species, but nowadays it has been decreasing in numbers progressively, so in 2015 the IUCN changed the species status to “endangered”.
