Thousands of white cranes arrive in Momoge Wetland in groups. What are the migration habits of white cranes?

Jilin Momoge National Nature Reserve welcomes migratory birds to the south, and more than 2, cranes have come to Momoge National Nature Reserve to dock and transport. Due to the heavy precipitation in spring and summer this year, the water level of the river in the upper reaches of Momoge Wetland has risen, and the amount of water in the wetland is deep, which has a certain impact on the crane stop. Red-crowned cranes fly from the south of China to Siberia to breed, and return to the south with live red-crowned cranes when the weather turns cold in autumn. According to the statistics of the staff of the reserve, the proportion of young cranes this year is about 11%. The crane will stay in Momoge Wetland for about 2 days to feed, and then fly to Poyang Lake for the winter.

cranes usually live alone, in pairs or in families, but most of them are large groups. Cranes are very vigilant. In order to ensure the safety before sunset, cranes gather in the lake from all directions to dive overnight. Early in the morning, they flew to the shallow water with abundant food, stood guard, looked around and called for distant companions, and soon there were many, many. In particular, large groups of hundreds or even thousands of people gathered before the migration were swept away overnight by the updraft. These signs seem to be pre-arranged and very harmonious with each other, which is difficult for us to understand. The reason why cranes come to Momoge wetland on time in spring and autumn every year is because cranes with the strictest requirements for habitat have a strong attachment to shallow wetlands.

Momoge Wetland has more than 11, acres of fresh water and open wetlands. White cranes like to eat plants, aquatic plants and animal food. The purpose of their coming here is to quickly replenish food and lay the foundation for their breeding in the north and their winter trip in the south. Migration ensures that cranes live in an optimal climate, which is conducive to obtaining rich and diverse food sources, breeding and expanding their living space, natural balance and evolution. The ability of a crane to determine its direction from thousands of miles away is a mystery in nature. It shows the family and group foraging activities of white cranes in Momoge wetland in the morning and evening, especially the wonderful moment of white cranes flying in the air during migration. ?
