Abstract
<jats:p>This article presents the first published results on the spatial ecology of Golden Eagles (Aquila chrysaetos) in Central Asia, using GPS/GSM telemetry. Movements of three juvenile Golden Eagles were followed. The eaglets were tagged in the nest, two in Russia (2018, 2023), and one in Kazakhstan (2024). The duration of the post-fledging dependence period (PFDP) varies from 89 to 124 days, averaging 109±18 days. The home range sizes of eagles during the PFDP, calculated as 100% MCP, varied from 2.67 to 1177.56 km² (averaging 642.16±594.32 km²). Daily flight activity averaged 1.64±1.17 h (based on the most detailed track), corresponding to 13.4±10.34% of the total daylight hours. The average flight altitude of the birds varied from 79.19±44.33 m to 217.41±102.55 m, depending on the season and landscape, and was highest during migration. The natal dispersal process and transition to a territorial lifestyle in the tracked female culminated in a nesting attempt at age three. The data obtained are important for understanding the ontogenesis of eagle behavior and developing scientifically based conservation measures for the species, particularly in the context of wind energy development and other anthropogenic threats.</jats:p>
