摘要

The diet of the Long-legged Buzzard Buteo rufinus was investigated west of Jurf A1 Darweesh area, southern Jordan. 19 intact regurgitated pellets and 15 fragmented pellets yielded 56 individual prey items representing seven species (two small mammals, two agamid lizards, one frog, one unidentified bird, and one grasshopper). Small mammals, reptiles, birds, and grasshoppers constituted 75%, 19.64%, 1.8%, and 3.6 % of the diet, respectively. Prey items were dominated by the Fat Sand Rat Psammomys obesus (38 individuals) and the Starred Agama Stellagama stellio (6), followed by the Long-eared Hedgehog Hemiechinus auritus (4), an unidentified agamid lizard (4), grasshoppers (2), a toad (1), and an unidentified bird (1). The results suggest that the Long-legged Buzzard preferred hunting diurnal, ground-dwelling small mammals. It was selective for higher-energy-yielding mammalian prey (P. obesus), yet showed some opportunistic feeding habits likely influenced by prey availability. We recommend that hunting areas of raptors be investigated during the site-selection of development projects such as renewable energy.

Obesus)有选择性,但展示了一些机会主义饲养习惯,可能受到猎物可用性的影响。我们建议在开发项目的场地选择期间调查猛龙队的狩猎领域,如可再生能源。
