In early winter, the Yellow River Delta National Nature Reserve in Dongying, East China's Shandong province, reaches the peak of its migratory bird season.
Over 60,000 geese, ducks, and other waterfowl gather in the 6,700-hectare ecological restoration area, creating breathtaking spectacles during their flights.
Traditionally, researchers monitored bird populations using telescopes, requiring extensive expertise and fieldwork. However, advancements in technology have transformed this process.
The reserve now features over 200 surveillance cameras and 18 AI recognition points. In collaboration with the Chinese Academy of Sciences, the reserve developed an intelligent bird identification system capable of real-time monitoring of species and numbers. For instance, this system helps conservation efforts by tracking the endangered Oriental white stock's nesting and breeding behaviors.
Since October, the reserve has recorded over 140,000 birds from 84 species, including 223 Oriental white stocks, 60,000 waterfowl, and rare species such as black storks and spot-billed ducks. Additionally, an integrated system that monitors birds and water conditions ensures a stable habitat essential for feeding and nesting.
Through ecological restoration and technological advancements, the number of bird species in the reserve has grown from 187 to 374, with Oriental white stock breeding pairs exceeding 450 and black-headed gull populations steady at 10,000. Furthermore, the reserve is now a critical overwintering site for red-crowned cranes, with 389 recorded in 2023.
The Yellow River Delta Nature Reserve exemplifies the harmony of ecological preservation and modern science, ensuring a thriving future for migratory birds.
