Abstract

The contents of regurgitated Eagle Owl (Bubo bubo ascalaphus) pellets collected in Kharga Oasis, Egyptian Western Desert, were analyzed. The owl's diet consisted mostly of mammalian prey: 89% of the total number of vertebrates recovered and 70·9% of the total live weight of vertebrates identified. Mus musculus was the most common prey item; other small mammals, including bats, were also taken. Birds comprised 10·1% of the total number of vertebrates recovered and 29·0% of the total live weight of vertebrates identified. Insects and reptiles made up a small portion of the diet. On the basis of these animal remains it is clear that Eagle Owls are able to adjust their diet to exploit seasonally available prey.
