Abstract: Aimed to reduce the accident of potential bird strike at Wuhai civil airport, an investigation was made on the bird communities in 7 habitat types in the airport and its surrounding areas from August 2009 to July 2010, with the avian diversity indices analyzed. A total of 106 avian species belonging to 37 families and 16 orders were recorded, of which, 78 species were native progenitive, and 28 species were non-progenitive. Based on the importance value, and combined with distribution coefficient, grouping behavior, and the behavior of traversing or flying above the runway, the 106 species could be divided into four types of hazard grades, i.e., catastrophic hazard, serious hazard, substantial hazard, and minor hazard. According to the investigation data and the analysis of the main environmental factors attracting birds, the countermeasures for bird strike avoidance at the airport were proposed.
