中文摘要:
      利用卫星跟踪对出生于甘肃盐池湾国家级自然保护区(以下简称盐池湾)内的黑颈鹤(Grus nigricollis)幼鸟在越冬地撞击电线死亡的现象以及可能造成的影响进行研究。2018和2019年两年的7和8月在盐池湾内为16只黑颈鹤幼鸟安装卫星跟踪器。之后每日在Tracker Client软件中对黑颈鹤幼鸟的行动进行实时监测,发现异常行为后随即通知当地志愿者对幼鸟撞击电线进行确认。2019和2020年1至3月在西藏林周县开展实地调查,对发生撞击的电线位置进行记录并留存黑颈鹤残骸的影像资料。采用线性模型分析2013至2020年盐池湾黑颈鹤种群数量随时间的变化趋势。研究结果显示,2018年出生的黑颈鹤,其撞击死亡率为40.0%;2019年出生的黑颈鹤撞击死亡率为83.3%;撞击电线是该黑颈鹤种群幼鸟在越冬地死亡的主要原因。撞击事件大多集中发生于河谷地带,该处分布有大量农田。撞击发生前幼鸟的活动区域内均有电线分布,幼鸟与电线发生过相互作用。线性模型分析显示,盐池湾黑颈鹤种群除成年个体外,幼鸟和亚成体的数量均呈上升趋势。幼鸟在越冬地的撞击死亡并未给该种群的数量造成严重影响,但鉴于撞击事件的严重性,仍建议在黑颈鹤越冬地为电线采取防鸟撞措施,同时对燃放爆竹等情况加以适当引导,尽量减少对黑颈鹤的干扰。
英文摘要:
      From July to August in 2018 and 2019, 16 Black-necked Crane (Grus nigricollis) juveniles born in Yanchiwan National Nature Reserve, Gansu (hereinafter referred to as Yanchiwan) were installed with satellite trackers. Here we studied the death of these satellite-tracked birds caused by colliding with power lines over the winter and its possible effects. After the satellite trackers were installed, with daily real-time monitoring of the action of the juveniles in the Tracker Client software, we immediately notified local volunteers to confirm if the juveniles had died of colliding with power lines after abnormal actions been found. From January to March in 2019 and 2020, the field survey was carried out in Linzhou County, Tibet, to record the locations of the power lines with which the juveniles collided and the image data of the remains of the Black-necked Cranes. The linear model was used to analyze the changes over time in the number of the Black-necked Cranes in the Yanchiwan from 2013 to 2020. We found that the mortality of the Black-necked Cranes born in 2018 and 2019 were 40.0% and 83.3%. Colliding with power lines was the main reason for the death of the Black-necked Crane juveniles of the population in wintering area. Most of the collision locations were concentrated in the river valley (Fig. 1), where there was a large amount of farmland (Table 2). Before the collision, there were power lines scattering in the active area of the juveniles, and the power lines had interacted with the juveniles (Table 1). The linear model results showed that in the Yanchiwan Black-necked Crane population, except for adults, the numbers of juveniles and subadults were on the rise (Fig. 3). The mortality of juveniles in the wintering area did not seriously affect this population. We recommend to take measures to prevent bird strikes on the power lines in the wintering area, and at the same time, properly guide the setting off of firecrackers to minimize interference with Black-necked Cranes.
