The possible consequences of top predators for the success of restoration actions for animals is still poorly understood. Our main objective was to analyze whether there could be a risk of creating habitats with an excess of predation by top predators when carrying out actions to improve cliff habitats for cliff‐nesting birds at mining sites. We surveyed 28 mining sites in Spain to obtain information regarding the Eagle Owl's (Bubo bubo) presence and diet, and analyzed its relationship with the density of cliff‐nesting birds and rabbits (Oryctolagus cuniculus, its main prey) at the mining sites. We detected Eagle Owls in 18 mining sites (64%) and collected enough prey remains in 11 mining sites. A total of 732 minimum number of prey were identified. The diet of the Eagle Owl consisted mainly of mammals (83%) and the proportion of birds in the diet was low (13%). There was no relationship between the presence of Eagle Owls and the density of rabbits in the mining sites, but there was a positive relationship with the density of cliff‐nesting birds. We conclude that the Eagle Owl does not seem to exert significant pressure on the cliff‐nesting birds, even on wild pigeons, the most abundant cliff‐nesting birds in its diet. Restoration projects which promote cliff‐nesting birds would not entail a significant risk of generating ecological traps by excess of predation by the Eagle Owl. Furthermore, this species could be favored in restoration plans, as it is a threatened species in some areas in Europe.

雕sites在采矿场的存在和饮食：对悬崖cliff鸟的恢复和管理的意义

顶级捕食者对动物恢复行动成功的可能后果仍然知之甚少。我们的主要目的是分析在采取行动改善采矿现场悬崖栖鸟的悬崖栖息地时，是否存在由顶级掠食者创造过度捕食的栖息地的风险。我们对西班牙的28个采矿场进行了调查，以获取有关鹰Bu（Bubo bubo）的存在和饮食的信息，并分析了其与筑巢鸟类和兔子（穴兔的密度）之间的关系。，它的主要猎物）在采矿现场。我们在18个采矿场（64％）中检测到鹰Eagle，并在11个采矿场中收集了足够的猎物。总共确定了732个最小猎物。雕O的饮食主要包括哺乳动物（83％），鸟类在​​饮食中的比例很低（13％）。雕sites的出现与采掘场中兔子的密度之间没有关系，但与悬崖峭壁上的鸟类的密度有正相关。我们得出的结论是，雕O似乎并没有对筑巢悬崖的鸟，甚至是野鸽，其饮食中最丰富的筑巢悬崖的鸟，没有施加很大的压力。促进悬崖筑巢鸟类的恢复项目不会因鹰O过度捕食而产生生态陷阱的重大风险。此外，
