The swan is a large migratory bird, its body length is about 1.5m and its weight can exceed ten grams. The body is covered with white feathers, the bill is mostly black, and the upper part of the bill to the nostrils is yellow. Moreover, its head and neck are relatively long, accounting for about half of its body length. Swans like to live in groups in lakes and swamps, feeding mainly on aquatic plants. Overwinter and rest in the warmer climate in the south.

The swans mainly live in open lakes, ponds, swamps, slow-flowing rivers and adjacent tundra areas and tundra swamps during the breeding season. In winter, they mainly rest on reeds and cattails. It also likes to appear in large lakes, reservoirs, ponds and river bends with other aquatic plants. It also likes to appear in wet meadows and flooded plains, swamps, beaches and estuaries. Some swans will even appear in farmland. Just like this time, a large number of swans appeared in the fields in Shiga Prefecture, Japan.

White swans feed on roots, stems, leaves, seeds of aquatic plants, molluscs, insects, earthworms, etc. Swans have a very gentle temperament and often travel in groups. It is active during the day and is very good at flying and swimming. It can also walk on the ground. When flying, its head is extended forward and the paws are directed toward the back of the abdomen. Swans have no fixed home except during breeding season.

The white swan is a migratory bird that mainly lives in reedy lakes, reservoirs and ponds. In order to avoid the cold, white swans that live in Siberia often migrate to southern China to spend the winter when the weather turns cold.

White swans like to build nests in clusters. They can lay eggs and reproduce in other seasons except summer, with an annual birth of more than 20. During the breeding season, female swans lay eggs and male swans guard them. Only female swans take turns hatching. After 35 days, the cygnets hatch out of their shells. The newly hatched cygnets have gray-white feathers and can swim in the water after a few days. They often go to the water with their parents to look for food. If disturbed, they will hide under their mother's wings.

The white swan has a fixed spouse and implements the one-man-one-term system. It seems that we need to protect the living environment of the white swan.
