摘要

Knowing the winter behaviour is essential for deciding on conservation strategies for threatened migratory species such as the greater spotted eagle (Aquila clanga). Fidelity and inter-annual variation in winter home range of an Estonian greater spotted eagle were studied during the first four years of its life by means ofGPS satellite telemetry in south-eastern Spain. Results show the eagle exploited a small area (1 2.7 km2, 95% kernel) with high inter-annual fidelity during all winter stages. The A. clanga preferred marshes and water bodies and avoided irrigated crops and urban areas. Waterfowl hunting did not show any effect on the spatial pattern of the eaglea€?s behaviour, although water level management in reservoirs could influence their use by the A. clanga. Our study highlights that the wintering home range may be limited to a small suitable habitat patch where human activities, especially water reservoir management, should be regulated
