China Biological Diversity Protection and Green Development Foundation (referred to as the China Green Fair and Green Association) neighborhood biological diversity protection working group noticed that just yesterday, the 2022 China International Services Trade Fair (referred to as the "Service Trade Club") was officially officially officially. The mascot -Fuyan, the main image is based on Swift. Little Swallow appeared in the 2022 service meeting in this way, which shows the cultural value of biodiversity.

Swift in Beijing belongs to the Swift Swift Swift, which is slightly larger than the common swallows. Their appearance is streamlined, the flight speed is extremely fast, and it is a well -known insect -eating bird. In addition, Beijing Swift, as the only migrant bird named after "Beijing", is also a iconic species in Beijing, and one of the ecological symbols in Beijing.

The Biological Protection and Green Development Foundation of China has organized a group of volunteers. Since 2014, it has installed tracking instruments for Swift to explore its migration route between northern my country and Africa. Initially, they caught 30 Swift in a pavilion in the Summer Palace and installed the light -sensitive geographical positioning device on them. This small and exquisite instrument could record the flight trajectory of Swift according to light and temperature. One year later, volunteers captured 13 of the swallows in the same place in the Summer Palace, so as to read the information stored in the positioning device through software, and analyzed the migration route of Swift in Beijing.

Since then, people have been paying attention to this "footbird" relocation route. Recent studies have shown that this migrant species, April of each year, Beijing Swift arrived in Beijing to build nest breeding from southern Africa, and returned to southern Africa to overwinter from the end of July to the beginning of August.

So what is the role of Swift in Beijing's biological diversity? Beijing, like other parts of the world, is facing the sharp disappearance of biological diversity. The number of Swift has declined since its reform and opening up. According to the survey data provided by the 2014 China Biological Diversity Protection and Green Development Foundation (referred to as the China Green Fair and Green Association) Bird Watching Working Committee, Beijing Swift was only about 3,000 at that time. The disappearance background is mostly due to the decrease in traditional buildings. The buildings such as urban buildings, temples, and ancient towers have been demolished. It is difficult for Swift to find a harbor that can build nests.

Fortunately, in recent years, with the continuous advancement of the construction of ecological civilization, the protection of Swift has received increasing attention, and the number of populations has also been picked up.

Today, Swift has become a mascot of the China International Services Fair (Service Trade Association) in 2022, which once again explained that the cultural value of biodiversity is huge. We must protect biodiversity in order to last for a long time to enjoy the various ecosystem service functions brought by diverse life.
