【上千只鸿雁“安家”北京南海子公园】
The number of swan geese hatched in Beijing’s Nanhaizi Park hit a record high this year, with the total population exceeded 1,000 at peak times. The migratory water bird is a Class II nationally protected wild animal in China. 10 monitoring cameras have been installed in key spots in the park, enabling remote observation of the entire breeding cycle without human intrusion.

今年，南海子公园新孵化鸿雁突破新高。从建园初期不足10只的零星过境，到如今上千只鸿雁过境停歇，南海子用十余年时间，实现了鸿雁从“过客”到“居民”的身份转换。鸿雁是国家二级重点保护野生动物，东亚特有的迁徙水鸟，也是南海子公园极具代表性的野生水鸟种群。南海子园区还引入了10台监测摄像头和360度慢直播设备，实现繁殖期远程观测鸿雁繁育全流程，避免人工进区惊扰亲鸟，可精准掌握繁殖巢数、幼鸟成活率。
