Introduction to migratory birds: Millions of geese, ducks and other waterbirds inhabit East Dongting Lake every year, among which the Lesser White-fronted Goose accounts for more than 60% of the global population and is one of the most typical migratory birds in the reserve. This area also plays a very important role in regional species conservation networks such as the Northeast Asian Crane Migration Network, the East Asian Geese and Duck Migration Network, and the East Asia-Australia Wader Migration Network, and is known as "the hope for saving the world's endangered species." and “a model of harmonious coexistence between man and nature.”
