Movements of imperial eagle Aquila heliaca juveniles and description of monitored areas in the border zone between Austria, Hungary and Slovakia

Five juveniles of the imperial eagle were tracked during 2011-201 2. Movements were monitored in the western part of Slovakia and in the border area between Austria, Hungary and Slovakia. Three eagles came from the Záhorská nížina Lowlands and the others from the Malé Karpaty Mts and the Podunajská nížina Lowlands. Post-fledging movements were recorded in areas around the nests. Post-fledging areas covered a large territory (minimum convex polygons - 89, 941 , 969 km2). During the postfledging period the eagles carried out exploratory flights (1 2-33 km from the nest). One temporary settlement area (TSA) was identified in the border area between Austria, Hungary and Slovakia (minimum convex polygon - 68 km2). Two eagles with radio transmitters were recorded in this area. In the TSA and the post-fledging areas two habitat categories were dominant: arable land and forests. Heterogeneous agricultural areas were also important in the TSA (8%).
