Abstract:[Objectives] Mitigating bird strike is a worldwide challenge. The Domestic Pigeon (Columba livia domestica) is the most common bird in airport biodiversity surveys, and is one of the historically high-risk species for bird strikes. It is also the only species that has caused serious bird strikes due to manual release in large numbers. [Methods] From September 2020 to January 2021, we conducted 272 satellite tracking experiments for 681 hours on 149 pigeons (distance from the airport was 0.2﹣9.1 km, with an average of 1.2 km) from 23 households around 4 airports to observe individual flight behaviors (Appendix 1). The specific data of flight period, flight distance and flight height were obtained, and the potential bird strike risk of flight behavior was analyzed, so as to provide a reference for the airport to mitigate the bird strike risk of domestic pigeons. [Results] A single release of pigeons for 1﹣4 h accounted for 78%, 0﹣1 h accounted for 8%, and more than 4 h accounted for 14%. The average flight period is 2.9 ± 1.6 h, the shortest flight period is only 20 min, and the longest flight period is 9 h (Fig. 2). The flight of pigeons from 6:00 to 8:59 accounted for 16%, 9:00 to 11:59 accounted for 24%, 12:00 to 14:59 accounted for 26%, 15:00 to 17:59 accounted for 28%, and 18:00 to 20:59 accounted for 6%. In the dynamic process of free release and return of pigeons, the number of pigeons flying in the afternoon is more than that in the morning, especially from 15:00 to 17:59, when the number of pigeons flying is the largest (Fig. 3). The flight distance of domestic pigeons is usually within 3.0 km, up to 8.9 km. Among the four airports, the flight distance of domestic pigeons tracked in Airport A was mostly between 0.3 and 0.6 km, and up to 4.1 km. The flight distance of pigeons tracked by Airport B is usually between 0.4 km and 3.0 km, up to 8.9 km. The flight distance of pigeons tracked in Airport C was mostly between 0.3 and 0.6 km, and up to 5.2 km. The flight distance of pigeons tracked in Airport D was mostly between 0.1 and 0.6 km, and up to 3.4 km. The flight range of pigeons from 45% of the households overlapped with the airport. Among the four airports, Airport A was not overlapped with the flight range. In Airport B, the flight range of pigeons from 67% of households overlapped with the airport. In Airport C, the ratio of households is 50%, and in Airport D is 45% (Appendix 2). The flight height of 99% of the pigeons was at or below 200 m, and only 1% was above 200 m. Among the four airports, the flight height of 80% of the pigeons near Airport A was 0﹣100 m, while the flight height of most of the pigeons near Airport B (90%), Airport C (89%) and Airport D (89%) was 0﹣50 m. The average flight height of domestic pigeons was 29 ± 28 m (Fig. 4). [Conclusion] The results showed that, the time period in the afternoon, especially from 15:00 to 17:59, should be taken as the key time period of domestic pigeon prevention. And, the area of 10 km around the airport and the height from 0 to 200 m should be taken as the key space range of domestic pigeon prevention. According to Article 58 of the Civil Aviation Law of the People's Republic of China (2021 Amendment), it is clearly stipulated that "birds and other objects that affect flight safety shall not be kept or released". It is necessary to establish corresponding accountability mechanisms and strengthen effective supervision to mitigate the risk of domestic pigeon bird strike.
