摘要

2013/2014年冬季,在斯洛伐克中部的Bojnice Spa,长耳猫头鹰的栖息地由两个亚群组成,它们彼此相距12米。每隔一个月,研究人员就两个亚群的饮食和猫头鹰离开巢穴的方向进行研究。松树亚群的猫头鹰与杉木亚群的猫头鹰相比,离开巢穴的方向明显不同。在这两个亚群中,普通田鼠是最容易被猎杀的猎物。然而,比较两个亚群的替代猎物,木鼠和其他哺乳动物在云杉亚群的颗粒中发现的频率明显更高,而鸟类在松亚群的颗粒中发现的频率更高。我们的研究结果表明,两个亚群捕获的猎物不同可能是由于不同的狩猎区域和不同的可选猎物种类的结果。

Different alternative diets within two subgroups in a winter roost of long-eared owls
Abstract In winter 2013/2014 a roost of long-eared owls in Bojnice Spa (central Slovakia) was formed by two subgroups situated 12 meters apart from each other. The diets of both subgroups and the direction of the owls’ departure from the roost were studied at monthly intervals. Owls of the Pinus-subgroup left the roost in a significantly different direction compared with the owls in the Picea-subgroup. The common vole was the most hunted prey in both subgroups. However, comparing the alternative prey of the two subgroups, the wood mouse and other mammals were found significantly more often in pellets of the Picea-sub-group, whereas birds were more frequent in pellets of the Pinus-subgroup. Our results suggest that the different prey hunted by the two subgroups may be a consequence of diverging hunting areas with different availability of alternative prey species.
