Summer greenery thrives along the Hangzhou Bay. Sightseeing boats laden with visitors part the emerald waves, weaving through reed marshes where egrets skim the water and waterfowl glide peacefully... The scene evokes imagery from the “Book of Songs”: "By riverside are cooing, a pair of turtledoves."

wildlife photographers, and conservation technicians. They guide visitors through wetland ecosystems mentioned in the ancient poetry while interpreting avian behaviors, species identification, and ecological knowledge. "Which bird flies the fastest?" "How do birds sleep in trees?" "What's the wingspan of the longest-winged bird?"...

"Children's curiosity about birds knows no bounds," said volunteer Hu Yong. "Their eager eyes when receiving answers are our greatest reward."

During the season, visitors may choose sightseeing boats or kayaks to navigate reed "mazes" for bird encounters, or observe through telescopes at designated stations. "The egret flocks were spectacular! I captured them all on my phone," said Ms. Su from Guangzhou, adding "Immersing in this harmony between humans and the nature is unforgettable."

Birds are wetland ecosystems' “barometer”. As the Hangzhou Bay's ecological capacity improves, biodiversity flourishes. Monitoring shows the park has documented 303 bird species, including 62 under national protection. Stationed year-round at monitoring posts, researchers Zhu Xiaohong and Xu Xiajuan endure 40°C heat with heavy gear to document birds. "Providing primary research data is our duty," they said. "Watching migratory birds thrive makes all the sweat worthwhile," Xu Xiajuan noted.
