On the diet of the Pharaoh Eagle Owl, Bubo ascalaphus (Savigny, 1809), in Qatar, with an overview of its feeding habits
البيانات الوصفيةعرض كامل للتسجيلة
The diet of Bubo ascalaphus in Qatar was assessed based on pellets collected from the first known nesting site of the species in the country. The pellets contained a total of 68 prey items, representing 9 different species: 4 mammals, 1 bird, 1 reptile, and at least 3 scorpions. Mammals clearly comprised the major food source (89.7% and 97.7% in frequency and biomass respectively). Our data suggest that Pharaoh Eagle Owls are opportunistic predators that feed on a variety of prey depending on their temporal/spatial availability, which is consistent with previous studies. A literature review clearly suggests that Eagle Owls in arid to semi-arid environments are opportunistic predators with small mammals being their main prey. Predation on migrating Blue-cheeked Bee-eaters Merops persicus supports this hypothesis.
