【摘要】 2019年10月,在苍鹰(Accipiter gentilis)秋季迁徙中途停歇地,长岛保护区为4只苍鹰佩戴了卫星追踪器,跟踪研究其迁徙路线和迁徙停歇地。其中:3只苍鹰完成了2019年秋季、2020年春季和秋季的往返迁徙,1只苍鹰仅完成了2019年秋季和2020年春季迁徙。卫星追踪结果表明:苍鹰越冬于中国长江下游和鲁中山区,繁殖于俄罗斯莫斯科和中国东北地区;越冬地和繁殖地均为山脉附近。苍鹰春季和秋季迁徙路线基本相同,主要沿着松嫩平原-辽东湾-胶东半岛-长江下游方向南北迁徙,但迁徙路线并不重叠,重要中途停歇地包括大兴安岭、长白山、老铁山、长山列岛、崂山等,松嫩平原为长期补给停歇地。同一只苍鹰个体春季和秋季迁徙距离和时间差异不明显;在春季和秋季,苍鹰采用不同的迁徙策略飞越渤海海峡。此外,追踪发现,苍鹰在森林区域停歇和活动频次明显高于农田、水边、草原等生境。更多还原

【Abstract】 In October 2019, four Accipiter gentilis at the Changdao reserve were fitted with satellite trackers to track their migration routes and resting places during their fall migration. Among them, three Accipiter gentilis completed the round-trip migration in autumn 2019, spring 2020 and autumn, and one only completed the round-trip migration in autumn 2019 and spring 2020.The results of satellite tracking showed that goshawk overwintered in the lower reaches of the Yangtze River and the mountainous areas in central Shandong Province of China, and bred in Moscow of Russia and northeast China.The wintering and breeding grounds are near the mountains. The migration routes of the Accipiter gentilis in spring and autumn are basically the same,mainly along the direction of Songnen Plain-Liaodong Bay-Jiaodong Peninsula-the lower reaches of the Yangtze River, but the migration routes do not overlap. The important stopover sites include the Great Hinggan Mountain, Changbai Mountain, Laotie Mountain, Changshan Islands, Laoshan Mountain, etc, while Songnen Plain is the long-term supply stopover site.The migration distance and time of the same Northern Goshawks in spring and autumn were not significantly different.In spring and autumn,Northern Goshawks use different migration strategies to fly across the Bohai Strait. In addition, it was found that the frequency of resting and moving of Northern Goshawks in forest area was significantly higher than that in farmland, waterside and grassland.更多还原
