  • Status of the Eastern Imperial Eagle Aquila Heliaca in Bulgaria Between
    Chancellor, R. D. & B.-U. Meyburg eds. 2004 Raptors Worldwide WWGBP/MME Status of the Eastern Imperial Eagle Aquila heliaca in Bulgaria between 1994 and 2002 Stoycho Stoychev, Ivelin Ivanov, Tzeno Petrov, Simeon Marin5Dimitar Demerdzhiev, Gradimir Gradev and Dobromir Domuschiev ABSTRACT In Bulgaria between the years 1994 to 2002, research, monitoring and conservation activities on the Eastern Imperial Eagle significantly increased. The total Bulgarian population is estimated to be between 20 to 25 pairs. Fifteen nest sites were discovered. Most of the areas important for breeding are located along the border with Turkey in the Sakar Mountains (7 nests) and Strandja mountains -Dervent Heights (5 nests). The majority of the territories (86%) are located in areas of elevation between 150 and 400m. Seventy-six percent of the nests discovered were in poplar trees. During the nine years of study, almost 65% of the breeding attempts surveyed were successful. The mean breeding success was one young per occupied nest and 1.54 chicks per successful nest. However, during the years 1998-2000, which coincided with an increase in the number of monitored nests, the breeding success was between 0.83 and 0.91 fledglings per occupied nest. The adult birds were mainly sedentary, spending the winter in the breeding territories. Three wintering and temporary settlement areas important for immature birds were identified. The main threats to Imperial Eagles in Bulgaria are: disturbance, cutting of poplar trees and abandonment of pastures INTRODUCTION At the end of the 19th century, Imperial Eagles Aquila heliaca were widespread throughout Bulgaria. Leverkuhn (after Boev 1978) reported 1,824 nests.

  • Aquila Heliaca -- Savigny, 1809
    Aquila heliaca -- Savigny, 1809 ANIMALIA -- CHORDATA -- AVES -- ACCIPITRIFORMES -- ACCIPITRIDAE Common names: Eastern Imperial Eagle; Aguila Imperial; Aguila Imperial Oriental; Aigle impérial; Asian Imperial Eagle; Imperial Eagle European Red List Assessment European Red List Status LC -- Least Concern, (IUCN version 3.1) Assessment Information Year published: 2015 Date assessed: 2015-03-31 Assessor(s): BirdLife International Reviewer(s): Symes, A. Compiler(s): Ashpole, J., Burfield, I., Ieronymidou, C., Pople, R., Wheatley, H. & Wright, L. Assessment Rationale European regional assessment: Least Concern (LC) EU27 regional assessment: Near Threatened (NT°) In Europe this species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size may be small, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern in Europe. In the EU27 the small population size qualifies for Vulnerable under the population size criterion (<1,000 mature individuals), but as population size is increasing in the EU27 and in Europe, the final category is adjusted to Near Threatened.

  • Records of Globally Red-Listed Bird Species Migrating Through the Besh Barmag Bottleneck, Azerbaijan Republic
    Podoces, 2016, 11(2): 43–52 PODOCES 2016 Vol. 11, No. 2 Journal homepage: www.wesca.net Records of Globally Red-listed Bird Species Migrating through the Besh Barmag Bottleneck, Azerbaijan Republic Michael Heiss Vogelwarte Hiddensee, Zoological Institute and Museum, Ernst Moritz Arndt University of Greifswald, Soldmannstraße 23, 17489 Greifswald, Germany Article Info Abstract Original Research Several migratory bird species have undergone rapid population decline in recent decades for various reasons. The immediate detection Received 12 August 2016 of such declines is necessary to prevent their extinction. One Accepted 9 December 2016 important tool for such detections is long-term monitoring at bird migration count sites, which are often located at migration Key words bottlenecks. Such a bottleneck was recently discovered at Mount Besh Bird migration Barmag in the Azerbaijan Republic. Studies carried out at this site Besh Barmag bottleneck revealed the passage of an estimated 1.24–1.51 million migrant birds Azerbaijan Republic in autumn 2011 and 0.65–0.82 million in spring 2012. Among 278 bird species recorded in these studies, 34 are thought likely to exceed the 1% criterion of the world or flyway populations, making them valuable target species for long-term monitoring programmes. Six of these species are considered by the IUCN Red List as threatened or near threatened. A further 22 globally threatened or near threatened bird species were also observed. The present paper discusses these 28 species focusing on numbers, phenology and suitability for long-term monitoring projects. 1. Introduction One method of gathering such information is Migratory birds as a group of animals to carry out bird migration counts at so-called interacting on a global scale are exposed to ‘bottlenecks’, where a concentration of global changes and threats in various ways migratory birds takes place along coastlines or within their breeding, wintering and passage in association with topographical barriers areas.

  • Spatial Structure in the Diet of Imperial Eagles Aquila Heliaca in Kazakhstan
    JOURNAL OF AVIAN BIOLOGY 37: 594Á600, 2006 Spatial structure in the diet of imperial eagles Aquila heliaca in Kazakhstan Todd E. Katzner, Evgeny A. Bragin, Steven T. Knick and Andrew T. Smith Katzner, T. E., Bragin, E. A., Knick, S. T. and Smith, A. T. 2006. Spatial structure in diet of imperial eagles Aquila heliaca in Kazakhstan. Á J. Avian Biol. 37: 594Á600. We evaluated the relationship between spatial variability in prey and food habits of eastern imperial eagles Aquila heliaca at a 90,000 ha national nature reserve in north- central Kazakhstan. Eagle diet varied greatly within the population and the spatial structure of eagle diet within the population varied according to the scale of measurement. Patterns in dietary response were inconsistent with expectations if either ontogenetic imprinting or competition determined diet choice, but they met expectations if functional response determined diet. Eagles nesting near a high-density prey resource used that resource almost exclusively. In contrast, in locations with no single high-density prey species, eagles’ diet was more diverse. Our results demonstrate that spatial structuring of diet of vertebrate predators can provide important insight into the mechanisms that drive dietary decisions. T. E. Katzner (correspondence) and A.

  • Status of the Eastern Imperial Eagle Population in Slovakia Between 1977 and 2013 Stav Populácie Orla Kráľovského Na Slovensku V Období 1977–2013
    Slovak Raptor Journal 2014, 8(1): 9–15. DOI: 10.2478/srj-2014-0005. © Raptor Protection ofSlovakia (RPS) Status of the eastern imperial eagle population in Slovakia between 1977 and 2013 Stav populácie orla kráľovského na Slovensku v období 1977–2013 Jozef CHAVKO, Lucia DEUTSCHOVÁ, Štefan DANKO, Jozef MIHÓK, Bedřich LANDSFELD, Jiří PAVELKA, Ladislav ŠNÍRER, Stanislav HARVANČÍK, Andrej DUBRAVSKÝ, Leonidas PREŠINSKÝ & Richard GALAŠ Abstract: Between 1977 and 2013 nesting of 72 different pairs of imperial eagle was recorded in Slovakia. The nesting popula- tion in Slovakia is concentrated in two subpopulations with the nesting area distant about 200 km. In Eastern Slovakia nesting of 42 pairs was recorded whilst in Western Slovakia 30 pairs were nesting. Authors present results of 37 years period of survey focused on distribution and trend of nesting population, as well as habitat preferences of the species. The paper compares results from Western and Eastern Slovakia. From Western Slovakia further data are evaluated, such as threats negatively influencing the population, period of hatching and other aspects of nesting biology. During the survey period the number of known nesting pairs in Slovakia has increased from five in 1977 to 53 in 2013. In total, 908 nesting events have been recorded during this period with 642 successful nesting events and 1,080 fledglings. In Western Slovakia the pairs prefer foothills, whilst in Eastern Slovakia most of the pairs nest in lowlands. Strong anthropic pressure is significantly influencing the distribution and size of the population as well as the habitat preferences of the species. Abstrakt: V rokoch 1977 až 2013 bolo na Slovensku evidované hniezdenie 72 rôznych párov orla kráľovského.

Box 50, BG–1111 Sofia, Bulgaria, e–mail: [email protected] Since 1990, nature conservation NGOs are the main players in the running of nation-wide research and monitoring schemes for raptors in Bulgaria. Among them, the Bulgarian Society for the Protection of Birds (BSPB) and Green Balkans are most active, covering the most threatened diurnal raptors in the country. The key species covered by comprehensive monitoring schemes are the Imperial Eagle Aquila heliaca, White-tailed Eagle Haliaeetus albicilla, Egyptian Vulture Neophron percnopterus, Griffon Vulture Gyps fulvus, Black Vulture Aegypius monachus, Saker Falcon Falco cherrug and Red-footed Falcon F. vespertinus. Information on their distribution, numbers, breeding success, productivity, diet, movements etc. is gathered on annual basis. The Buzzard Buteo buteo and Kestrel F. tinnunculus are also regularly monitored at the national level by the Common Bird Monitoring scheme. Distribution of all raptor species has been studied for the purpose of the Atlas of Breeding Birds in Bulgaria. The contemporary satellite telemetry methods revealed important aspects of movements and threats to eagles and vultures from Bulgaria within the country and abroad. Main threats for the raptors in Bulgaria are related to habitat loss, unnatural mortality and disturbance. The main gaps in raptor monitoring in Bulgaria are related to the lack of coverage of most of the diurnal species and owls.
