Poyang Lake, also known as Poyang Lake, is the largest freshwater lake in China and the second largest lake in China. The vast lake meets the sky, and the waves surge first; Reaching the sea through the river, with a broad mind, nourishes life year after year. Poyang Lake receives water from five rivers: Jiangxi, Fuzhou, Guangxi, Rao and Xiu, and is connected with the Yangtze River.

The rainy season is surging and boundless, and water and sky are connected; In the dry season, the water falls on the beach, with weeds and reeds; The mountains and peaks of the lake stretch, the sand mountains rise and fall, the fields are thousands of miles, migratory birds fly, and cattle and sheep wander.

The beautiful and rich Poyang Lake has nurtured all the creatures that have lived by the lake for generations.

Rare birds frequently appear in Poyang Lake;

"In recent years, the number of rare birds in Poyang Lake has increased than before," said Zeng Nanjing, head of the scientific research department of Poyang Lake National Nature Reserve Administration, who has been involved in bird investigation for decades.

Waterbirds that did not appear in Poyang Lake before or with low frequency have frequently appeared in people's field of vision in recent years, such as red-billed diving duck, half-webbed snipe, red snipe, colorful snipe and so on, which is one of our most intuitive feelings about the changes of waterbirds in Poyang Lake in recent years.

In the summer waterfowl survey in June this year, a pair of endangered migratory birds, the blue-headed diving duck, and seven young birds were found playing freely in a certain water area of Poyang Lake. "The adult bird of the blue-headed diving duck has not only changed from a' migratory bird' to a' resident bird', but also completed natural breeding in Poyang Lake, and the breeding state is very good, indicating that this extremely endangered migratory bird has settled in Poyang Lake to reproduce." Wen Sibiao, a waterfowl investigator who witnessed this scene, told reporters that waterfowl surveys often have surprises.

Poyang Lake is of great significance to the protection of global biodiversity, and it is an irreplaceable wintering place for crane, an extremely endangered species in the world.

"98% of the world's white cranes, more than 80% of the oriental storks and more than 70% of the white-naped cranes are wintering in Poyang Lake Nature Reserve, which is also the wintering ground for the largest swan population in the world and the largest cygnet population in China. There are more than 10 species of snipe migrating between the northern and southern hemispheres in the world to supplement food in Poyang Lake. " Zeng Nanjing said.

From June 10 to March of the following year, Poyang Lake came out of the beach, dotted with lakes, lush wetlands and fragrant wild flowers, and 300,000 to 400,000 migratory birds came here for the winter.

Bird experts have found that the species of waterbirds coming to Poyang Lake for the winter are increasing. For example, from 2017 to 2018, 74 species of waterfowl were detected in nature reserves, which was the highest value in nearly 10 overwintering period.

Speaking of the changes in bird ecology, Liu, a staff member who has worked in the Bureau for nearly 20 years, found that the feeding grounds of birds in Poyang Lake are constantly expanding: "In the past, they only fed in the protected area, but now they have expanded their feeding grounds outside the protected area."

Liu believes that the change of birds' foraging habits may be related to the change of vegetation growth caused by seasonal water level changes in Poyang Lake. On the other hand, it may also be related to the better protection of migratory birds by wetlands, which makes migratory birds feel more secure. "Birds are bold."

In the past 10 years, seven protection stations were added around Poyang Lake, bringing the total number of protection stations in the whole lake to 1 1. Since 20 1 1, Jiangxi Province has also arranged 1 ten thousand yuan every year to assess and reward the protection of migratory birds in wetlands around the lake.
