AB The Bonelli’s Eagle (Aquila fasciata) is a critically endangered species in Israel, with electrocution on power lines posing a serious threat to its population. Because retrofitting of electricity pylons to prevent mortality is a slow and costly process, it is important to prioritize the pylons in the network for quick and efficient mitigation of eagle mortality. To determine which pylons need to be retrofitted, we applied a three-stage maximum entropy modeling process for identifying the risk factors posed by different environmental variables. The environmental feature with the highest correlation to electrocution is the distance to reservoirs (i.e., many electrocution events occur near water reservoirs). The reservoirs are foraging hotspots for Bonelli’s Eagles in Israel’s arid environment. Electricity pylons powering the reservoirs’ pumping facilities tend to be the highest perches in the vicinity of many of the reservoirs, creating an ecological trap. The strong attraction of reservoirs to eagles may explain the high level of selectivity indicated by the model, suggesting that retrofitting only 3.6% of the pylons in the network would achieve 77% reduction in eagles’ electrocution probability. Moreover, insulating pylons according to the model will also likely reduce electrocutions of other avian species, including Eastern Imperial Eagle (Aquila heliaca) and White-tailed Eagle (Haliaeetus albicilla). The modeling process presented here yielded two electrocution risk maps, one to facilitate prioritization of mitigation in Israel’s existing power network and the second to support planning and designing new infrastructure. The model may help reach conservation goals for Bonelli’s Eagle and may also be useful in prioritizing pylon retrofitting in other arid landscapes.

AB 博内利雕（学名：Aquila fasciata，英文名：Bonelli’s Eagle）是以色列境内的极危物种，输电线路触电是其种群面临的严重威胁。由于对输电塔进行绝缘改造以避免鸟类致死的过程缓慢且成本高昂，因此优先处理电网中的塔架以快速高效地缓解雕类致死风险至关重要。为确定需要改造的塔架，我们采用三阶段最大熵建模流程，识别不同环境变量带来的触电风险因素。与触电事件相关性最高的环境特征为距水库的距离，即多数触电事件发生在水库附近。在以色列的干旱环境中，水库是博内利雕的觅食热点区域。为水库抽水设施供电的输电塔往往是诸多水库周边最高的栖息点，由此形成生态陷阱。雕类对水库的强烈吸引力或可解释模型体现出的高度选择性，这表明仅对电网中3.6%的输电塔进行改造，即可将雕类触电概率降低77%。此外，按照该模型对输电塔进行绝缘处理，还可能减少其他鸟类的触电致死事件，包括东方帝雕（学名：Aquila heliaca，英文名：Eastern Imperial Eagle）与白尾海雕（学名：Haliaeetus albicilla，英文名：White-tailed Eagle）。本文提出的建模流程生成两张触电风险地图：一张用于助力以色列现有电网的改造优先级排序，另一张用于支持新基础设施的规划与设计。该模型既可助力实现博内利雕的保护目标，也可用于在其他干旱景观中优先安排输电塔改造工作。
