We report the size and density of an Egyptian Vulture population in Turkey and provide insight into its nest site selection patterns. The study was carried out at Beypazar (Turkey), holding one of the densest Egyptian Vulture populations (six pairs per 100 km(2)) in the Western Palearctic. Random Forests analysis revealed that human impact was a potential factor governing the distribution of nest sites, as the pairs clearly preferred to breed away from nearby villages, towns or roads. Utilisation of elevation gradient and aspect was similar to other studied populations, with the probability of nesting increasing at lower altitudes and for south-facing cliffs. Nearest-neighbour distance between nests was about 1.5 km, indicating territorial behaviour when choosing nest sites at the local scale. Our findings provide guidance for nature conservation NGOs and related government bodies for their various actions including designation of Important Bird Areas, regulation of mining practices and preparation of environmental impact assessments.

Current status of Great Bustard Otis tarda in Turkey: population size, distribution, movements, and threats
Akarsu, FERDI·; Özgencil, İbrahim Kaan; Gürsoy Ergen, Arzu ; Saygılı-Yiğit, Fulya ; Karakaya, Muharrem; Soyluer, Melisa; Soyluer, MELÄ°SA (2021-01-01)
The Great Bustard Otis tarda is a globally threatened species with populations inhabiting the steppe zones of Turkey. In recent decades, its populations in Turkey have suffered severe declines in range and size. Although the remaining populations are in urgent need of protection, there has been no national-scale study on the species since 2009, and huge information gaps remain concerning its range, abundance, and movements in the country. Here, we combined data from five years of fieldwork together with all...

Breeding success and reproductive behavior in a white stork (ciconia ciconia) colony in Ankara
Göcek, Çağrı; Bilgin, Cemal Can; Department of Biology (2006)
White Stork ( Ciconia ciconia, Linnaeus, 1758) is a summer visitor and passage migrant in Turkey. Although being widespread in summer near wetlands of Turkey, except for the eastern and western parts of the Black Sea Region, there has been no research on this species involving regular monitoring of nests. In this study, breeding success and survival of nestlings in a population in Kızılcahamam-Ankara as well as behavioral differences among nests and their probable consequences on breeding success were studi...
Breeding biology, population size and spatial distribution of a common nightingale (Luscinia megarhynchos Brehm, 1831) Population at Yalıncak (Ankara)
Özbahar, İlker; Bilgin, Cemal Can; Department of Biology (2005)
Many bird populations are known to show strong territoriality as well as high site fidelity during breeding. The Common Nightingale (Luscinia megarhynchos) is one of many such migratory species that annually occupies the same favourable habitat. Especially dominant males prefer to breed in the same area every year, and high fidelity probably assures high breeding success. This study aims to investigate breeding biology, population size and spatial distribution of nightingales at a small area in Yalıncak wit...
Genetic structure analysis of honeybee populations based on microsatellites
Bodur, Çağrı; Kence, Aykut; Department of Biology (2005)
We analyzed the genetic structures of 11 honeybee (Apis mellifera) populations from Türkiye and one population from Cyprus using 9 microsatellite loci. Average gene diversity levels were found to change between 0,542 and 0,681. Heterozygosity levels, mean number of alleles per population, presence of diagnostic alleles and pairwise FST values confirmed the mitochondrial DNA finding that Anatolian honeybees belong to north Mediterranean (C) lineage. We detected a very high level of genetic divergence among p...
