Transboundary frontiers often contain wildlife habitats that are fractured by geopolitical borders, which could have adverse effects on the wildlife that inhabit those areas. We examined the movement, breeding, roosting, and diet of 15 GPS-tagged barn owls (Tyto alba) along the Israeli-Jordanian and Israeli-Palestinian Authority borders. Our results showed that 80% of the barn owls hunted across the border. On average, the owls engaged in 5.4 hunting trips per night, 16% of which were cross-border excursions, and they crossed the borders as frequently as expected randomly, highlighting the importance of wildlife protection on all sides. Hunting movement, rather than cross-border activity, had an effect on the annual reproductive success and diet composition. Specifically, female owls that spent more time at the nest and engaged in longer distance hunting trips had higher reproductive success. Eighty percent of the females roosted outside of the nest box at a median distance of 908 m (range = 199–4112 m). Only 13.3% of the owls (2/15 owls) roosted across the border. These results increase our understanding of the movement, breeding, and roosting behavior of a non-migratory avian raptor. However, a serious lack of cooperation and communication between bordering countries hampers our ability to understand the full effects of differing environmental policies on a species that knows no borders.

越境边界通常包含因地缘政治边界而破裂的野生生物栖息地，这可能对居住在这些地区的野生生物产生不利影响。我们检查了15只带有GPS标签的谷仓猫头鹰（Tyto alba）的运动，繁殖，栖息和饮食）沿以色列-约旦和以色列-巴勒斯坦当局的边界。我们的结果表明，有80％的谷仓猫头鹰在边境狩猎。平均而言，猫头鹰每晚进行5.4次狩猎旅行，其中16％是跨境旅行，它们按预期的频率随机越境，突显了各方保护野生动植物的重要性。狩猎运动，而不是跨界活动，对年度生殖成功和饮食组成有影响。具体而言，在巢中花费更多时间并进行更长距离狩猎旅行的雌性猫头鹰繁殖成功率更高。80％的雌性栖息在巢箱外部，中位距离为908 m（范围= 199–4112 m）。只有13.3％的猫头鹰（2/15猫头鹰）栖息在边境上。这些结果增加了我们对非迁移性禽猛禽的运动，繁殖和栖息行为的了解。但是，邻国之间严重缺乏合作与沟通，妨碍了我们了解不同环境政策对无国界物种的全面影响的能力。
