Top-predators, including birds of prey, play an important role in ecosystems and are good bioindicators (Sergio et al. 2005). Links between the presence of predators and the overall biodiversity of a particular habitat mainly focus on trophic relationships (Roth and Weber 2008, Sergio et al. 2008b, Burgas et al. 2014). However, top-predators not only have food requirements, but also need to build large, safe nests (Danko 2007). The building and occupancy of such nests by birds of prey are of the greatest importance for several reasons. The nests are often used for many years, due to the huge costs in time and energy of their construction, that, at least theoretically, offer possibilities of their use by many other animals for feeding, roosting and as breeding sites (Konrad and Gilmer 1982, Jiménez-Franco et al. 2014).

小规模的生物多样性热点：鹰巢对许多其他动物的重要性

顶级捕食者，包括猛禽，在生态系统中发挥着重要作用，并且是良好的生物指标（Sergio 等人，2005 年）。捕食者的存在与特定栖息地的整体生物多样性之间的联系主要集中在营养关系上（Roth 和 Weber 2008、Sergio 等人 2008b、Burgas 等人 2014）。然而，顶级掠食者不仅有食物需求，还需要建造大而安全的巢穴（Danko 2007）。由于几个原因，猛禽建造和占据这种巢穴是最重要的。由于建造巢穴的时间和能源成本巨大，这些巢穴经常使用多年，至少在理论上，这些巢穴为许多其他动物提供用于喂养、栖息和繁殖场所的可能性（康拉德和吉尔默，1982 年） , Jiménez-Franco 等人，2014 年）。
