How rare is it for swans to play in the Swan Lake in Handan after the wind and dust?

1. In Swan Lake, Jize County, Handan, Hebei Province, groups of white swans play on the lake. It was the coldest day since winter in Jize County, Handan City, Hebei Province. Swan Lake is frozen in a large area, attracting white swans who like ice and snow to come water skiing. The beautiful white swan is naturally fond of ice and snow. They swim in the lake, climb and play on the ice, and become a striking ecological landscape in winter.

Second,

I have seen some unknown birds in Beihu Lake, but I have never seen swans. The news caught his attention at once. At about 8 o'clock yesterday morning, when Mr. Li passed the North Lake on his way to work, he paid special attention to this swan, hoping to see its face. He really saw five white swans swimming on the water. ? Living in the village all the time, it is not uncommon to see wild ducks in the lake, but it is the first time for the white swan! ? He told reporters excitedly.

After receiving the clue, the reporter immediately rushed to Suri Village. After searching, the reporter saw five beautiful white swans playing and foraging in the north of Beihu Lake. According to the reporter's visual observation, these five swans are similar in posture, with a body length of more than one meter, white feathers all over, yellow mouth near the head, black tips and occasionally black feet. At this time, the North Lake has begun to freeze, and the swan is slowly sliding on the distant water with its slender neck, which is very reassuring against the dark brown reeds. Sometimes they swim gracefully, sometimes they flap their wings and fly in the water, but most of the time they stick their heads in the water for food.

In this regard, the reporter consulted Zhang Zhiwei, captain of the feeding team of Congtai Park Zoo in Handan City. He said that the swans stayed here temporarily during the migration, and after two or three days of replenishment and physical recovery, they will continue their migration journey. Zhang Zhiwei said swans usually migrate in groups. Since it is the late stage of migration, these five swans should fly as far as Shandong or Jiangsu. He said that Handan is the only way for migratory birds to migrate, and swans only feed and rest here temporarily. He also told reporters that the swan has a protective film on its eyes. When they are foraging, they stick their heads in the water and look for food with their eyes open.

It is understood that swan is a migratory bird, mainly living in reedy lakes, reservoirs and ponds. It is an omnivore, feeding on the roots, stems, leaves and seeds of aquatic plants, mollusks, insects and earthworms. It is docile and moves in groups.
