Population surveys of Eastern Imperial Eagles in Anatolia between 2009 and 2013
Márton Horváth, István Béres, Tibor Juhász, András Kleszó, András Kovács and Jose Tavares 7th International Conference on the Conservation of the Eastern Imperial Eagle, 3 October 2013, Bratislava, Slovakia
Background • 2006: – status of imperial eagle is unkown in Turkey – active breeding site is not known – older data on 5-10 probable territorries
• 2007: – MME and BSPB expeditions: eagles are observed in 7 territorries (5 new)
• 2009-2013: – MME contracted by RSPB and Doga Dernegi (voluntary work, fuel costs reimburshed) – Final report by Dec 2013: data not analysed yet!
Methods • Systematic expeditions twice a year (all together 10) • March-April: searching active nest sites, checking incubation • June-July: checking breeding success • Usually 1 car with 4 people (all together 18 people) • 4-10 days (all together 60 days)
• Bolu, Eskisehir, Ankara, Corum and Cankiri admin. regions • Surveys covered probably 30-60% of their population • < 10% of potential habitats in Turkey
â&#x20AC;˘ Up to 100 nests have been found in 45 territorries â&#x20AC;˘ All tracklogs and data stored in GIS in the field
Bolu
â&#x20AC;˘ Most precisely surveyed â&#x20AC;˘ 25 territorries have been located

Conclusions • Surveys covered a very small fraction of the potential habitats of Turkey • Most probably the 3rd largest population in the world (after Russia and Kazakhstan) • Threats not known (shooting, electrocution and habitat destruction are definately huge problems!) • No local organization who can carry on the monitoring work • No conservation efforts at all • Networking and capacity building is urgently needed!
