On June 1, the banding work for the studies of Beijing swifts (Apus apus pekinensis) officially commenced. At the Summer Palace, volunteers conducted "health checkups" for swifts.

A total of 126 Beijing swifts were banded this time, including 88 already identified from previous years, marking a recovery rate of nearly 70 percent. Among them, three swifts, first banded at the Summer Palace in 2014, stand out with the longest recorded history of ten years. This indicates the overall good condition of the Beijing swifts' population at the Summer Palace. 

According to the survey data from Beijing Wildlife Rescue and Rehabilitation Center, the population of Beijing swifts is on a consistent rise.
