Liaohe River Estuary Wetland, with the reputation of “depot for migratory bird”, allows flocks of birds migrating southward to take a break to replenish their strengths. Migratory birds such as egret, swan, and red-crowned crane swim on the river to seek for food and fly high to hover over the water from time to time. The birds having fun along the river and reeds in the distance together form a harmonious ecological picture scroll.
