The Huangpi Lake Wetland in Hefei City, east China's Anhui Province, now hosts the dramatic annual winter "bird wave," transforming into a breathtaking stage for massive flocks of migratory birds in synchronized flight. As one of nature's most impressive aerial spectacles, tens of thousands of migratory birds have recently descended upon the lake, creating vast, fluid formations that ripple across the water at dusk and dawn. Seen from afar, the flocks resemble drifting ribbons of silk or a colossal mythical fish gliding through the sky. Against the clear winter sky and the warm glow of sunset, their precise, synchronized flights weave ever-changing patterns over the serene lake, breathing vibrant life into the scene. As a vital stopover along the East Asian-Australasian Flyway, Huangpi Lake marks the height of its birdwatching season from late November through February each year. The most striking "bird waves" are typically observed during the gentle light of early morning and late afternoon. By December 2025, over 100,000 wintering birds from 137 species have been recorded here, turning the wetland into a bustling haven for avian life and a visual feast for nature enthusiasts and photographers alike.
