Analysis of the Wintering Situation of Mergus Squamatus in Xinxian County,Henan Province

为研究中华秋沙鸭在河南省新县的越冬情况,以期更好地保护中华秋沙鸭,分别于2021年1月、2022年1月和2023年1月对新县中华秋沙鸭越冬种群进行了调查。2021年1月和2023年1月分别在小潢河监测到中华秋沙鸭最大种群13只和15只,2022年1月在石堰口水库监测到最大种群7只。中华秋沙鸭多次在小潢河流域出现10只以上越冬种群,表明生境良好的小潢河流域适宜中华秋沙鸭栖息,建议持续开展对中华秋沙鸭越冬种群及栖息地的保护与监测。
