Abstract

Abstract We report an exceptional case of Eurasian Eagle Owls Bubo bubo feeding on Stag Beetles Lucanus cervus in Germany, with the beetles making up 56.9% of all prey individuals. A review of literature and a comparison of data reveal that both the number and the biomass of the consumed beetles are typically too low to be of any nutritional importance with respect to the Eurasian Eagle Owl's broad food spectrum. Therefore, we conclude that Eurasian Eagle Owls merely opportunistically fed on this only seasonally available food source and that juvenile owls might prey on these beetles during their hunting exercises.

欧亚鹰鸮Bubo Bubo伺机捕食鹿甲虫Lucanus cervus

摘要我们报道了一个例外的欧亚鹰鸮Bubo Bubo在德国以鹿甲虫Lucanus cervus为食，这种甲虫占所有猎物的56.9%。对文献的回顾和数据的比较表明，食用甲虫的数量和生物量通常都太低，相对于欧亚鹰鸮的广泛食物范围而言，不具有任何营养重要性。因此，我们得出结论，欧亚鹰鸮只是机会主义地以这种唯一季节性可用的食物来源为食，幼年猫头鹰可能会在狩猎过程中捕食这些甲虫。
