英文摘要	The diet composition of the Desert or Pharaoh Eagle Owl Bubo ascalaphus, was investigated in Eastern Saudi Arabia. 112 regurgitated pellets yielded 203 individual prey items representing at least eleven rodent species, unidentified bird(s), at least one scorpion, and other unidentified insects. Prey items were dominated by rodents (91%) which were found in 96.4% of the pellets. Birds, scorpions, and other insects constituted 2.46, 5.91, and 2.96% of the diet, respectively. Rodents contributed the most in terms of biomass, with the black rat, Rattus rattus, and desert jirds dominating the remains. The results suggested that the Desert Eagle Owl in the arid ecosystem in eastern Saudi Arabia is a highly selective feeder, hunting 1-5 prey items per day (mean +/- SD 1.77 +/- 0.96) mostly from ground-dwelling native and invasive rodents. Prey selection within this human-influenced area likely influenced by the availability and abundance of species and shifting to urban rodents.
