place of swans, winter migratory birds. Songjiho, lagoon, was once a part of the sea. It became a lake, for accumulation of the sand flowed in from a river had separated it from the sea. Lagoons along the East Coast have a unique ecological environment in which freshwater lives, oceanic lives, and lives living in both freshwater and sea live together. Such an ecological environment was created by the geological characteristics of a lagoon where freshwater and seawater are mixed naturally as freshwater flows in from a river and seawater from the border on the sea through the chapped spot. Songjiho is even in depth and abundant in fish, for in addition to existing freshwater fishes such as carps and crucian carps, sea fishes including gray mullets, daces, and Salgansaengi flowed in through Songhogyo by high sea, tidal waves, or rainy spell. It was designated as the national tourist resort in 1977; accordingly, construction of beach resorts and various amusement facilities attracts a number of tourists continuously.

Paradise for Winter Migratory Birds, Swans

There are 8 species of swans all over the world, and Korea has 3 species of them, that is, whooper swans, swans, and black swans in winter. Whooper swans usually live in Northern Europe during summer. They move south by way of the Midwest and the East Coast in Korea and pass the winter dispersed in rivers, reservoirs, grassy and damp areas, and seashores; then, they move more toward the south in flock when water is frozen and as beautiful queens of winter catch our eyes. Whooper swans are largest in number among the wintering kinds of swans. They migrate southward not because it's cold but because they can't get any food and starve to death if water is frozen. So they stay and inhabit wherever water isn't frozen They can be found in the areas where water isn't frozen in Korea in winter. They were designated as the 21st natural monument to protect.
