摘要

2015年，在巴勒斯坦伯利恒的Wadi Al Makhrour，用新鲜和几年前的颗粒研究了欧亚鹰鸮(Bubo Bubo)的饮食。从研究的颗粒中发现了3种节肢动物、1种爬行动物、至少4种鸟类和6种哺乳动物。最常见的猎物为黑鼠(Rattus Rattus)(37.0%)，其次为南方白胸刺猬(Erinaceus concolor)(29.4%)和鸟类(21.8%)。比较最近的和旧的颗粒显示出饮食成分的变化。与旧的相比，最近的颗粒含有更多的Rattus Rattus。较旧的颗粒包括更多的自然存在的物种，如三棱角鼠、古氏鼠和埃及褐家鼠，这些在较新的颗粒中是不存在的。

Change in diet of the Eurasian eagle owl (Bubo bubo) suggests decline in biodiversity in Wadi Al Makhrour, Bethlehem Governorate, Palestinian Territories

Abstract The diet of the Eurasian eagle owl (Bubo bubo) was studied in Wadi Al Makhrour, Bethlehem, Palestinian Territories in 2015 with fresh and several year old pellets. Three species of arthropods, one reptile species, at least four bird species, and six species of mammals were recovered from the studied pellets. Black rat (Rattus rattus) was the most common prey (37.0%), followed by the southern white-breasted hedgehog (Erinaceus concolor) (29.4%) and birds (21.8%). Comparison of recent and older pellets showed change in diet composition. Recent pellets contained more Rattus rattus compared to older ones. Older pellets included more naturally-occurring species such as Meriones tristrami, Microtus guentheri, and Rousettus aegyptiacus, which were absent in newer pellets.
