Abstract:

Bird strikes threaten civil and military aircrafts. It is necessary to understand the community of birds around the airport and its nearby areas to avoid bird strikes. We surveyed avian community at Jiangbei Airport and its surrounding areas by using line transect method from June 2013 to May 2014. We recorded a total of 102 species belonging to 40 families and 15 orders, which included 44 residents, 30 summer migrants, 13 winter migrants and 15 passing migrants. Among these species, Passeriformes (54 species) was in the dominant position, accounting for 52.94% of the total species. We also found that the bird density was the highest in winter and the lowest in summer. The diversity index was the highest in autumn and the lowest in summer. The highest and lowest evenness indexes were observed in spring and summer, respectively, and the highest and lowest dominance indexes in summer and autumn, respectively. Considering the density, ADCvalue, bird strike risk value, relative bird strike risk percentage and habits of birds, the species closely related to bird strikes included Hirundo rustica, Sturnus cineraceus, Acridotheres cristatellus, Dicrurus macrocercus, Carduelis spinus, Phasianus colchicus and domestic species Columba domestica. Finally, we provided comprehensive suggestions and control measures for avoiding bird strikes at Jiangbei Airport in Chongqing.
