Хранителен спектър на скалния орел (Aquila chrysaetos) (Aves: Accipitridae) в Сърнена Средна гора (България)
Journal Title: Ecologia Balkanica - Year 2009, Vol 1, Issue 1
Abstract
Проучен е хранителния спектър на една двойка скални орли ([i]Aquila chrysaetos[/i] Linnaeus, 1758) гнездяща в Сърнена Средна гора. Материал от хранителни остатъци и погадки е събиран през 1999, 2000 и 2002 година от и под гнездото след приключване на размножителния период на птиците. От установените минимум 65 екземпляра от 10 вида животни в храната на скалните орли, повече от половината са костенурки ([i]Testudo[/i] spp.) (n = 26, 55.4%). Относително висок е процента и на таралежите ([i]Erinaceus roumanicus[/i]) (n = 9, 13.8%) и котките ([i]Felis[/i] spp.) (n = 5, 7.7%), повечето от които вероятно са домашни ([i]F. domesticus[/i]). Всички други видове животни са с нисък процент в храната на орлите от изследваната двойка.
