A preliminary study on 6 metal contents was extracted from 10 eagle owls (Bubo bubo) and 10 long-eared owls (Asio otus) in Beijing with Jobin Yvon-ULTIMA inductively coupled plasma. The heavy metal elements detected were included Chromium, Lead, Cobalt, Manganese, Nickel and Cadmium. And Cd(p=0.000) is the only element which had significant difference in different tissues of long-eared owls, but the elements of Cr（p=0.002），Ni（p=0.000），Co（p=0009），Cd（p=0.010）, Mn (p=0.002) had significant difference in different tissues of eagle owls. The highest content of Cr in long-eared owls′ tissues was from kidney, but in eagle owl was from brain. The lowest content of all the detected elements was Cd and the highest was Mn. The content of Ni in brain was higher than the other tissues in eagle owls, but the tissues had the highest content of Ni was thoracic feathers in long-eared owls. The content of Co was highest in long-eared owls′ kidneys, but lowest in eagle owls′ brains. This experiment also found that using back feathers was the best choice for the heavy metal detecting of long-eared owls and eagle owls.
