Wild mandarin ducks flock to Chongqing for the winter. What protective measures are there in Chongqing?

Due to the recent cold air, more than 30 wild Yunnan barbecues were held in winter two weeks ago.

Yuanyang is a rare and endangered bird. Every winter, there are more than 10,000 mandarin ducks in eastern and southern China. Although the number of mandarin ducks has greatly increased in recent years due to living environment, food shortage and environmental changes, few people think that the number of mandarin ducks has dropped sharply. These areas can't meet the needs of southern mandarin ducks in winter. As the weather gets colder and colder, there are more and more mandarin ducks in Baishan Jiayuan Park in Beijing and Tianjin Town, the catchment area of rivers and lakes.

June 5438+1October 65438+April 2022, in Baishan Hometown Park, JD.COM Town, the catchment area of rivers and lakes, this house can live in Lvxi Prefecture, sometimes standing on the beach, grooming, and sometimes living in rivers and lakes. Chasing each other in the water has added a lot of vitality to local civil servants. It is said that these days are due to the sudden cold weather in the north.

Why is this year earlier than previous years? It is reported that every year in June 5438+1mid-October, Yuanyang will migrate from north to south in winter. With the improvement of the local environment, the ecological environment for Yuanyang to move south is more demanding. As winter continues, the number of wild mandarin ducks here is gradually increasing. Mandarin ducks generally choose waters or bird's nest swamps instead of large-scale migration. The female mandarin duck and the male mandarin duck build nests and hatch eggs together. Each male mandarin duck can feed three to five ducks at a time, while male children are usually neck and neck. In the process of migration, Yuanyang will change according to the change of local environment during the flight. According to the data of the Central Meteorological Observatory, the temperature will drop rapidly in most parts of the north from June 5438+1October 15 to June 5438+1October/0/9, 2022, which is one of the main reasons for the great migration of Yuanyang. Winter goes from north to south.
