Abstract

Understanding the migratory route of raptors in their breeding and wintering grounds is crucial for ensuring their effective conservation. This study presents the preliminary findings through satellite telemetry to describe the summer and winter home ranges, movement ecology, activity, and migration routes of single individuals of Greater Spotted Eagle (Clanga clanga), Indian Spotted Eagle (Clanga hastata), Tawny Eagle (Aquila rapax), and Pallid Harrier (Circus macrourus). We calculated the home ranges as the minimum convex polygons (MCPs) and kernel utilisation distributions (KUD). Pallid Harrier had the smallest home range size of 4.29 km2 (95% MCP) and 3.98 km2 (95% KUD) in its breeding ground located in Russia, while the Greater Spotted Eagle had the largest home range size of 9331.71 km2 (95% MCP) and 5991.15 km2 (95% KUD) in Kazakhstan. The monthly and daily distances covered by tagged birds were significantly higher during migration. Our study also reports the first record of the winter and summer home range of the Indian Spotted Eagle in Pakistan. The tagged raptor used low elevation flyways than the straighter northern flyways over the Himalayan Mountain range, as found in another earlier study. Our study is the foremost satellite telemetry attempt from the region, highlighting important aspects of the migration route of migratory raptors to India.

中亚四种濒危猛禽的栖息地和迁徙路线:初步结果
了解猛禽在其繁殖地和越冬地的迁徙路线,对于确保它们的有效保护至关重要。本文通过卫星遥测技术,对大斑鹰(Clanga Clanga)、印度斑鹰(Clanga hastata)、褐鹰(Aquila rapax)和灰鹞(Circus macrus)的夏季和冬季栖息地、运动生态、活动和迁徙路线进行了初步研究。我们将home范围计算为最小凸多边形(mcp)和内核利用率分布(KUD)。白腹鹞的栖息地面积最小,为4.29 km2 (95% MCP)和3.98 km2 (95% KUD),其繁殖地位于俄罗斯,而大斑鹰的栖息地面积最大,为9331.71 km2 (95% MCP)和5991.15 km2 (95% KUD)在哈萨克斯坦。在迁徙期间,标记鸟的月和日覆盖距离显著增加。我们的研究还报告了印度斑鹰在巴基斯坦冬季和夏季栖息地的首次记录。另一项早期研究发现,带标签的猛禽在喜马拉雅山脉上空的飞行路线比在更直的北部飞行路线要低。我们的研究是该地区最重要的卫星遥测尝试,突出了迁徙猛禽到印度的迁徙路线的重要方面。
