Abstract: In order to understand the avian community and provide data for airport managers to avoid bird strike accidents, a bird survey was conducted using three transects and seven sampling points within a radius of 7 km at Shenyang Taoxian International Airport during September 2012 and August 2013. In total, 35 species of birds, belonging to 10 orders and 21 families, were recorded in five habitats including residential area, farming land, mountain, forest, and river. The Shannon diversity index, distribution coefficient and importance value of different avian species in the five habitats were calculated. Furthermore, the bird strike risk index for each bird species was calculated by multiplying the importance value and risk index. Accordingly, four risk levels were clarified as severe, heavy, moderate and low. Severe risk species included Passer montanus, Ardea cinerea, Pica pica, Falco tinnunculus. Heavy risk species included Hirundo rustica, Nycticorax nycticorax, Parus major, Columba livia. 16 species (such as Circus cyaneus, Anas platyrhynchos, Dendrocopos major, Cyanopica cyana) were included in the moderate risk group, and 10 species (such as Turdus chrysolaus, Gallinago megala, Coturnix coturnix, Coccothraustes coccothraustes) in the low risk group. This study provided strategies and suggestions for bird strike avoidance in the airport area.
