Beijing, January 7 (Youth.cn) - On January 6, 2025, migratory birds are hunting for food in the Yellow River Wetland in Dongbatou Village, Lankao County, Kaifeng City, Henan Province. Bean gooses, grey herons, egrets, whooper swans, and anatidae birds can be spotted. The countless birds look like tidal waves flying across the sky for tens of minutes. Photo/VCG
