鸟类卫报：“鸟类自助餐”已为湖南“客群”做好准备

Recently, Dongting Lake in central China's Hunan Province has entered the peak period of winter bird migration. The latest data shows that the current number of wintering birds in the eastern Dongting Lake has reached 100,000, with a total of 41 species recorded.（近期，湖南洞庭湖进入冬季鸟类迁徙高峰期。最新数据显示，目前东洞庭湖越冬鸟类数量已达10万只，共记录到41种。）

Thousands of wild ducks congregate in the waters of Caisang Lake within the eastern Dongting Lake, leisurely basking in the sun every day. Xiong Gaofeng, a longtime patrol officer stationed at Caisang Lake, has observed 19 species of wild ducks, with the falcated ducks being the main force in this area.（数以千计的野鸭聚集在东洞庭湖的采桑湖水域，每天悠闲地晒着太阳。长期驻扎在采桑湖的巡警熊高峰，观察到了19种野鸭，其中镰刀鸭是该地区的主力。）

Xiong said: "Now you can see birds here every day, and the water quality of Caisang Lake is getting better, attracting more and more birds. We have already entered the peak period of bird migration, and when the temperature drops further, more migratory birds will arrive."（熊高峰说：“现在这里每天都能看到鸟类，而且采桑湖的水质越来越好，吸引了越来越多的鸟类。我们已经进入了鸟类迁徙的高峰期，当气温进一步下降时，迁徙的鸟类也越来越多。鸟儿会来的。”）

In the waters of the eastern Dongting Lake, just a dyke away from Caisang Lake, various kinds of migratory birds are gathered in groups, gather in their own territories, undisturbed, to find their favorite foods. This year, the Junshan District of Yueyang City, integrated nearly 20,000 hectares of water in the Caisang Lake area of East Dongting Lake, revitalizing water resources, and establishing an intelligent fishery supervision system. Through measures such as meteorology, underwater sensing, and fish passage construction, staff of the district are monitoring real-time water dissolved oxygen levels, distribution of aquatic organisms, and establishing an underwater ecosystem, providing a natural feeding ground for wintering migratory birds.(在距离采桑湖仅一堤的东洞庭湖水域里，各种候鸟成群结队，聚集在自己的领地里，不受干扰，寻找自己喜爱的食物。今年，岳阳市君山区整合东洞庭湖采桑湖区域近2万公顷水域，盘活水资源，建立智慧渔业监管系统。该区工作人员通过气象、水下传感、鱼道建设等措施，实时监测水体溶氧水平、水生生物分布，建立水下生态系统，为越冬候鸟提供天然觅食地。)

An employee of the Junshan Ecological Fisheries Group in Hunan said they use the quantity of plankton to assess whether there is enough fish food in the water, which in turn estimates the size of the fish. This is important as fish are part of the diet for some migratory birds. Adequate food supply results in a large influx of birds, which is beneficial for their breeding and migration.(湖南君山生态渔业集团的一名员工表示，他们通过浮游生物的数量来评估水中是否有足够的鱼食，进而估算出鱼的大小。这很重要，因为鱼是一些候鸟的饮食的一部分。充足的食物供应导致鸟类大量涌入，有利于鸟类的繁殖和迁徙。)

This year, Yueyang City also took a series of measures including building water conservation facilities and restoring submerged vegetation in the Dongting Lake basin, improving the overall water retention capacity and expanding wintering bird habitats. According to the latest data, it is anticipated that the population of wintering birds in the eastern Dongting Lake will peak at the end of December, with the overall number exceeding 300,000.(今年，岳阳市还采取了建设洞庭湖流域水利设施、恢复沉水植被、提高整体蓄水能力、扩大越冬鸟类栖息地等一系列措施。据最新数据显示，预计12月底，东洞庭湖越冬鸟类数量将达到峰值，总数将超过30万只。)
