The breeding season 2009 was very good for the Eastern Imperial Eagle in Bulgaria. 20 young eagles fledged which is a new record. 6 of the nests were guarded by volunteers of the Bulgarian Society for the Protection of Birds and 8 young eagles fledged from those nests.
7 of the 20 young eagles are tagged with satellite transmitters to learn more about their survival and movements.
This is great news. Another record was achieved in Austria where 4 successful pairs raised 9 young. This is a success rate of 2.25 young fledged for every successful pair.
