Electrocution is a threat to birds and can undermine their conservation status. We tracked 15 globally endangered Egyptian vultures () in Oman and used Resource Selection Functions (RSFs) to identify habitats important to vultures and locate places where electrocution risk is high. During daytime vultures selected rugged areas with low vegetative cover, and habitats near roads, waste disposal sites, and both high (>50 kV, large pylons) and medium voltage electricity infrastructure. At night vultures also selected rugged habitats with scarce vegetation. At night high voltage infrastructure was selected, especially in areas of relatively low ruggedness at higher elevations; medium voltage infrastructure was avoided at night. The pattern of infrastructure use suggested that vultures were using large pylons for night-time roosting, but used both large pylons and smaller poles for perching during the day. 54.2 % of 11–33 kV powerlines in the study area were within the top six habitat suitability categories, which also contained 87.3 % of 34,778 vulture daytime test locations. Retrofitting powerlines overlapping the highest suitability zones would have the largest immediate impact. Areas surrounding landfills were also important: 10.34 % of all test locations were located within 2 km of landfills, which contained only 14.5 km of 11–33 kV lines. Targeting these areas would provide high impact at low cost. These maps are particularly useful in Oman because it is a stronghold for resident endangered large birds (i.e., Egyptian vulture, lappet-faced vulture ) and an important winter destination for endangered steppe eagles ().

描述阿曼濒危埃及秃鹫的生态资源利用特征，以更好地管理和减轻触电风险

触电对鸟类构成威胁，并可能破坏它们的保护状况。我们在阿曼追踪了 15 种全球濒临灭绝的埃及秃鹫 ()，并使用资源选择函数 (RSF) 来识别对秃鹫重要的栖息地，并找到触电风险高的地方。白天，秃鹰选择植被覆盖率较低的崎岖地区以及道路、废物处理场以及高压（> 50 kV，大型塔）和中压电力基础设施附近的栖息地。夜间秃鹫也会选择植被稀少的崎岖栖息地。夜间选择高压基础设施，特别是在海拔较高、崎岖程度相对较低的地区；夜间避免使用中压基础设施。基础设施的使用模式表明秃鹫在夜间栖息时使用大型塔架，但在白天则使用大型塔架和较小的杆子栖息。研究区域 54.2% 的 11-33 kV 电力线属于前六名栖息地适宜性类别，其中还包含 34,778 个秃鹫白天测试地点的 87.3%。改造与最高适宜区域重叠的电力线将产生最大的直接影响。垃圾填埋场周围的区域也很重要：所有测试地点的 10.34% 位于垃圾填埋场 2 公里范围内，其中仅包含 14.5 公里长的 11-33 kV 线路。针对这些领域将以低成本产生巨大影响。这些地图在阿曼特别有用，因为它是当地濒临灭绝的大型鸟类（即埃及秃鹫、垂面秃鹫）的据点，也是濒临灭绝的草原鹰的重要冬季目的地。
