Unusual cases of nesting by the Imperial Eagle (Aquila heliaca) in Eastern Slovakia [PDF]

Slovak Raptor Journal, 2012
Abstract Long-term monitoring of the Imperial Eagle in Eastern Slovakia has revealed that some pairs living permanently in an active agricultural environment (agrocoenosis) prove capable of adapting even to extreme conditions. In three cases eagles built their nests near railway lines (59, 22 and 15 m from the tracks), and in one case almost ...

Survey for Hemoparasites in Imperial Eagles (Aquila heliaca), Steppe Eagles (Aquila nipalensis), and White-tailed Sea Eagles (Haliaeetus albicilla) from Kazakhstan [PDF]

Journal of Wildlife Diseases, 2004
Prevalence of hemoparasites has been investigated in many avian species throughout Europe and North America. Basic hematologic surveys are the first step toward evaluating whether host-parasite prevalences observed in North America and Europe occur elsewhere in the world. We collected blood smears from 94 nestling imperial eagles (Aquila heliaca), five

Survival rate and mortality of juvenile and immature eastern imperial eagles (Aquila heliaca) from Bulgaria studied by satellite telemetry [PDF]

, 2014
A long-living species like A. heliaca has a natal dispersal period lasting several years. This period is crucial for the survival and conservation of the eagles. In this study we present mortality factors and the survival rate of juvenile and immature A.

Modelling populations of long-lived birds of prey for conservation: A study of imperial eagles (Aquila heliaca) in Kazakhstan [PDF]

Biological Conservation, 2006
Abstract Eagle populations worldwide are in decline and their demography is generally poorly understood. We use novel sensitivity analysis of stochastic simulation models to analyse the demography of the worlds highest-density and longest-studied population of eastern imperial eagles ( Aquila heliaca ), at the Naurzum National Nature Reserve in ...

SEASONAL AND INTERANNUAL DYNAMICS OF THE FEEDING SPECTRUM OF A PAIR OF GROUND EAGLES (AQUILA HELIACA, ACCIPITRIDAE, ACCIPITRIFORMES) IN THE RIGHT BANK OF THE MIDDLE VOLGA REGION (SENGILEEVSKY MOUNTAINS)

Russian Journal of Ecosystem Ecology
The food supply is a key factor determining the reproductive performance of populations of the large feathered predators. The distribution of the Imperial Eagle Aquila heliaca is primarily limited by the distribution and abundance of the main prey ...

Distribution, abundance, breeding parameters, threats and prey preferences of the eastern imperial eagle (Aquila heliaca) in European Turkey [PDF]

, 2014
During the period 2008-201 3, 32 different breeding territories were occupied by eastern imperial eagles (EIEs). These territories were mainly distributed in two regions: the Dervent Heights/Yıldız Mts. and the area to the north of the Marmara sea coast.

First breeding of the Imperial Eagle (Aquila heliaca) in the "Borská nížina" lowland (SW Slovakia)

Slovak Raptor Journal, 2008
First breeding of the Imperial Eagle (Aquila heliaca) in the "Borská nížina" lowland (SW Slovakia) In 2007, breeding of the Imperial Eagle in locality "Devínske jazero" lake (near the village of "Vysoká pri Morave", SW Slovakia) was observed. The pair fledged 2 young. This was the first recorded breeding of this species in the "Záhorie" region.
