候鸟翩跹彰显生态之美 描绘出和谐优美的鸟类交替生态图景

Core Viewpoint - The black-necked crane, the only crane species that breeds and lives in high-altitude areas, has successfully completed its migration to wintering grounds in Yunnan and Guizhou, while also welcoming a large number of swans from Siberia, indicating a healthy ecological exchange in the region [1][3][4]. Group 1: Migration and Population - The black-necked crane population in the Ruoergai Wetland National Nature Reserve is approximately 1,100 individuals, which have migrated successfully over a distance of 600 to 1,000 kilometers, taking 3 to 6 days to reach their wintering sites [4]. - The migration route of the black-necked crane serves as an important indicator of the ecological health of the Ruoergai wetland ecosystem, with migrations occurring annually from early November to the following spring [3]. Group 2: Conservation Efforts - The reserve has established a comprehensive protection system to ensure the survival and safe migration of black-necked cranes, implementing ecological measures such as grazing restrictions and habitat restoration [6]. - A smart monitoring system has been developed to track environmental factors and biodiversity, enhancing the protection of habitats for black-necked cranes and other bird species [6]. Group 3: Wintering Birds - The Ruoergai Wetland serves as both a departure point and a transit station for migratory birds, with around 200 swans currently wintering in the area, expected to stay until April of the following year [8]. - Recent arrivals from Siberia, including swans and white-tailed eagles, will be monitored for their population dynamics and health as part of ongoing winter bird monitoring efforts [10].
