The loss of traditional agropastoral systems, with the consequent reduction of foraging habitats and prey availability, is one of the main causes for the fast decline of Lesser Kestrel (Falco naumanni). To promote the conservation of the Lesser Kestrel and their habitats, here we studied the foraging activities patterns of this species during the breeding season. Between 2016 and 2017, we captured and tagged 24 individuals with GPS dataloggers of two colonies in Villena (eastern Spain) with the goals of estimating the home range sizes of males and females, evaluating the differences in spatial ecology between two colonies located in different environments: natural and beside a thermosolar power plant, and investigating habitat selection. Considering the distances before July 15, date until which it can be assured that the chicks remain in the nest in our colonies, there were significant differences with the distances to the nest in relation to the colony of the individuals: Lesser Kestrels from the thermosolar power plant colony had a greater average distance. The average size of home range areas was 13.37 km2 according to 95% kernel, and there were also significant differences in relation to colony: the individuals from the thermosolar power plant colony used a larger area (22.03 ± 4.07 km2) than those from the other colony (9.66 ± 7.68 km2). Birds showed preference for non-irrigated arable lands and pastures. Despite the differences between the two colonies, the home ranges of both are smaller or similar to those observed in other European colonies. This suggests that Lesser Kestrels continue to have adequate habitats and a good availability of prey. Therefore, the extension and proximity of the plant does not imply a great alteration, which highlights the importance of maintaining the rest of the territory in good conditions to minimize the impact.

小红est的家园范围如何受到大型民用基础设施的影响？

传统农牧业系统的丧失，进而导致觅食生境的减少和猎物的获得，是小K茶（Falco naumanni）迅速衰落的主要原因之一。为了促进对小茶and及其栖息地的保护，我们在繁殖季节研究了该物种的觅食活动模式。在2016年至2017年之间，我们使用GPS数据记录器捕获了西班牙维莱纳（西班牙东部）两个殖民地的24个人，并对其进行了标记，目的是估计男性和女性的居住范围大小，评估位于不同环境中的两个殖民地之间的空间生态差异：天然的和热太阳能发电厂旁边的，并研究栖息地的选择。考虑7月15日之前的距离 直到可以确定这些小鸡仍留在我们殖民地的巢穴中为止，相对于个体殖民地而言，巢穴之间的距离存在显着差异：来自热太阳能发电厂殖民地的较小Kestrels具有较大的平均距离。根据95％的谷粒，平均范围的平均面积为13.37 km2，并且与殖民地的关系也存在显着差异：来自热太阳能发电厂殖民地的人使用的区域面积更大（22.03±4.07 km2）菌落（9.66±7.68 km2）。鸟类表现出对非灌溉耕地和牧场的偏爱。尽管两个殖民地之间存在差异，但两者的居住范围都较小或与其他欧洲殖民地中观察到的相似。这表明小龙虾继续有足够的栖息地和充足的猎物。因此，植物的延伸和接近并不意味着会有很大的改变，这突出了保持其余地区处于良好状态以最小化影响的重要性。
