Core Viewpoint - The article discusses the migration of birds to Yunnan, highlighting changes in the scale, distribution, and protection measures for migratory birds this season [1] Group 1: Bird Migration Monitoring - In Yunnan's Ailao Mountain, over 1,400 migratory birds have been ringed since September, indicating active monitoring of bird migration [3] - Ailao Mountain is a significant migratory route, attracting birds from Siberia, Central Asia, and Xinjiang, making it one of the seven global migratory pathways [5] - The bird ringing station has monitored over 63,000 birds from 257 species over 22 years, providing essential data for studying migratory patterns [7] Group 2: Technological Advancements in Bird Monitoring - Researchers are employing various technological methods to enhance the comprehensiveness and accuracy of bird ringing efforts [8] - In 2024, tracking devices were placed on cuckoos, revealing their migration across continents, which surprised researchers [11] - Sound monitoring equipment has been installed to analyze calls from 1,200 bird species, successfully identifying several protected species [13] Group 3: Bird Protection and Conservation Efforts - Yunnan has 35 key migratory bird habitats, primarily located in Ailao Mountain, Hengduan Mountain, and Wumeng Mountain [15] - The region is a biodiversity hotspot, hosting over 1,032 bird species, including 268 nationally protected species [17] - Since the implementation of the 14th Five-Year Plan, Yunnan has established a comprehensive bird protection system, including hunting bans and migratory route protections [19] - Starting in 2024, Yunnan will designate important migratory route protection areas across 10 locations, enhancing conservation efforts [21] - Recent monitoring indicates a general recovery in bird populations, with a 15% increase in wintering waterbird numbers compared to 2020 [21]

本文转自【央视新闻客户端】； 又到了候鸟迁徙的季节。最近，云南迎来不少来此过冬的候鸟。今年迁徙季，当地候鸟规模、种群分部和保护手段都有什么变化？ 这些天，在云南新平县的哀牢山金山丫口，海拔2300米的山林间，鸟鸣声大清早就此起彼伏了。监测站工作人员说，入秋以来，候鸟已经在这里分批次"打 卡"，不同时段的迁徙种群各不相同。从今年9月开始到现在，哀牢山金山丫口已经环志的候鸟有1400多只。 每年秋冬季，从西伯利亚、中亚、新疆等区域南迁的候鸟一路南下，途中受东南方向沿海和西北方向青藏高原阻隔，很多候鸟聚集到哀牢山一线，使这里成 为全球7条候鸟迁徙通道之一。金山丫口候鸟环志监测站是典型的夜间迁徙鸟类环志点，每年有不少从事研究夜间迁徙鸟类课题的专家学者，都到金山丫口 的候鸟环志监测站开展科研工作。 云南大学生态与环境学院讲师 赵雪冰：我们发现，可能鸟对不同波长的光，它的趋光性是不一样的。 在云南巍山鸟道雄关，今年工作人员安装了两套鸟类声纹监测设备，能对途经区域内的1200种鸟类发出的叫声进行收集，并运用大数据分析迁徙候鸟的种类 和名称。鸟类声纹监测设备仅安装几天，就监测到国家一级保护野生动物金雕，以及国家二级保护野生动 ...
