Abstract:[Objectives] Bird collision refers to the phenomenon that birds collide with artificial facilities, causing injury or death to them. With the development of urbanization, bird collisions with buildings are becoming increasingly common. We conducted a 3-year bird collisions survey on Futian Mangrove Ecological Park Science Education Center in Shenzhen, Guangdong Province, a two-story building with glass covering on both sides of the whole exterior walls, to clarify the main factors causing bird collisions with the building and to evaluate the effectiveness of the bird-collide prevention measures that had been taken to it. [Methods] Park workers patrolled the building once an hour every day and night and recorded the occurrence of bird collisions from October 2019 to November 2022. In October 2020, a bird collision prevention renovation was carried out on the glass wall on the concave side of the building, which is close to the green space, mainly by sticking dot shaped stickers (the diameter of the dot is 1 cm, with a distance of 6.5 cm between the dots from the top to the bottom, and a distance of 10 cm from the left to the right) on it to prevent bird collisions and applying animal shaped stickers for decoration purposes (Fig. 1). Meanwhile, no intervention was taken to the glass wall on the convex side of the building, which is surrounded by harden ground. [Results] A total of 19 bird collisions were recorded in the survey, mainly occurred on the concave side glass wall of the building (n = 15), including 14 bird species, of which 10 were resident birds and 9 were migratory birds, and 14 were recorded as deaths (Table 1). Also, there were more bird collision records (n = 10) during autumn migration season (September to November) and all bird collisions occurred on sunny days. Based on the results and correlational research, we preliminarily evaluate that bird collisions with the Futian Mangrove Ecological Park Science Education Center are mainly related to the large scale of glass exterior wall of the building, the canvas shape of it, the distance between glass walls and green area, weather, and seasons. In this case, efforts have been made to reduce the bird collisions caused by glass wall. The bird collision records decreased from 11 (including 8 deaths) in the year before the implementation of bird collision prevention renovation, to 2 per year in next two years after the renovation (Fig. 2). [Conclusion] The results demonstrate that the measure of sticking specific dot shaped stickers on glass walls, a low-cost and low environmental impact approach, can significantly reduce bird collisions on glass walls. Since there are relatively few practical cases of bird collision prevention in public buildings in China, hopefully this practical case can provide reference for those management units, government departments and others who are interested in carrying out the design and renovation of bird collision prevention in artificial facilities.
