Summary
Each autumn, hundreds of thousands of Baikal teals converge on the Yellow River Estuary wetland in Dongying, Shandong, creating breathtaking aerial displays that resemble the mythical kun fish from Zhuangzi's classic Xiaoyao You. The 2025 winter season saw approximately 200,000 Baikal teals gathering at the site, alongside other duck species including green-winged teals and gadwalls, forming dynamic bird waves that have become a viral social media sensation. Through extensive ecological restoration efforts over recent years, this once-degraded wetland has been transformed into a thriving habitat for migratory birds.
Key Points
- The Yellow River Estuary wetland is located at the mouth of the Yellow River in Dongying, Shandong, formed after the river changed course in 1855
- The Baikal teal (花臉鴨), also known as the Baikal teal, is the main protagonist of the bird wave phenomenon, with approximately 200,000 arriving in winter 2025
- Best viewing season runs from October to December annually, when flocks perform coordinated aerial maneuvers creating wave-like formations
- The wetland suffered severe ecological damage from soil salinization, freshwater scarcity, and invasive smooth cordgrass (Spartina alterniflora)
- Restoration efforts included reconnecting water channels, ecological water replenishment, returning farmland to wetlands, and removing invasive species
- Native vegetation such as suaeda salsa and seagrass beds have been restored, providing essential habitat for migratory birds
- Photographers' footage of the "birds transforming into kun" phenomenon has gone viral on social media, drawing tourists to Dongying
Why It Matters
The Yellow River Estuary restoration demonstrates how targeted conservation interventions can revive degraded ecosystems and support dramatic recoveries in biodiversity, offering a replicable model for wetland conservation elsewhere. For Hong Kong birdwatching enthusiasts, the phenomenon highlights accessible world-class birding destinations in mainland China, while the viral "kun bird waves" trend may inspire increased eco-tourism interest in the Greater Bay Area.
