With the arrival of winter, wetland parks across Anhui Province welcomed the peak migration period of migratory birds. From swans, wild geese, egrets, wild ducks, to first-class protected animals like hooded cranes and oriental white storks, these birds either perch on the surface of the lake, circle and soar in the sky, or chase and play with each other. Magnificent wetlands have become a paradise for birds.
