湖北宜昌：珍稀夏候鸟数量明显增长，生态环境持续向好
中新网宜昌8月23日电 (董晓斌 舒仁庆) 记者23日从湖北省宜昌市林业和园林局获悉，该局在今年夏季开展的鸟类调查活动中，观测到国家二级保护鸟类7种，珍稀夏候鸟数量明显增长，展现了长江宜昌段生态环境持续向好的趋势。
宜昌地处三峡库坝区，是长江流域生态敏感区，近年来，宜昌市高度重视生态保护，全面推进长江宜昌段生态修复和绿色发展，打造了沿江自然风光带和一批国家湿地公园，为鸟类提供了良好的栖息环境。
今年8月初，宜昌市林业和园林局联合枝江金湖湿地公园等8个自然保护地及宜昌观鸟爱好者服务中心，共同开展了2024年夏季鸟类调查活动。调查结果显示，共观测到鸟类14目40科88种，累计观测到鸟类3746只。
华中农业大学教授李翔介绍，此次调查观测到了凤头鹰、黑鸢、游隼等多种珍稀鸟类，其中，灰翅浮鸥数量最多，两种国家二级保护动物水雉和蓝喉蜂虎种群数量也有明显增长。
李翔表示，水雉的繁殖筑巢需要浮水植物作为“硬环境”。此前，由于芡实种植减少，枝江金湖湿地公园的水雉数量有所下降。为此，金湖通过科学规划浮水植物种植，为水雉提供了更多“安家”场所。此次调查在金湖观测到水雉38只，显示水雉数量明显增长。
据了解，2023年，宜昌观鸟爱好者在宜昌市夷陵区黄柏河湿地公园一处蓝喉蜂虎巢穴进行繁殖期观测，发现成功繁殖5只雏鸟。今年，观鸟爱好者对同一区域进行繁殖观测后发现，该区域已有幼鸟14只，表明蓝喉蜂虎种群数量也呈现增长趋势。
宜昌市林业和园林局相关负责人表示，下一步将加大对珍稀夏候鸟分布区域的科研监测频次，自然保护地管理机构也将进一步优化夏候鸟繁育环境，提升长江宜昌段生态修复质量，为更多珍稀鸟类提供安全舒适的栖息地，持续推动长江生态环境保护工作。

Yichang, Hubei: Number of Summer Migratory Birds Shows SignificantIncrease, Reflecting Improved Ecological Environment
Yichang, August 23 (Xinhua) – The Yichang Forestry and Horticulture Bureau in Hubei Province reported on August 23 that a bird survey conducted this summer observed sevenspecies of birds under national second-class protection, indicating a significant increase in the number of rare summer migratory birds. This reflects the ongoing positive trend in the ecologicalenvironment of the Yichang section of the Yangtze River.
Located in the Three Gorges Reservoir area, Yichang is an ecologically sensitive zone in the Yangtze River basin. In recent years, Yichang has prioritized ecologicalprotection, comprehensively promoting ecological restoration and green development along the Yichang section of the Yangtze River. It has created a natural scenic belt along the river and a number of national wetland parks, providing a favorable habitat for birds.
Inearly August this year, the Yichang Forestry and Horticulture Bureau, in collaboration with eight natural reserves including the Zhijiang Jinhu Wetland Park and the Yichang Birdwatching Enthusiasts Service Center, jointly conducted the 2024 Summer Bird Survey. The survey results showed a total of 88 species from40 families and 14 orders, with a total of 3,746 birds observed.
Li Xiang, a professor at Huazhong Agricultural University, noted that the survey observed various rare birds, including the Crested Serpent Eagle, Black Kite, and Peregrine Falcon. Among them, theWhiskered Tern was the most abundant, and the populations of two national second-class protected animals, the Pheasant-tailed Jacana and the Blue-throated Bee-eater, also showed significant growth.
Li Xiang explained that the Pheasant-tailed Jacana requires floating aquatic plants for its breeding nests. Previously, the number of Pheasant-tailed Jacana in the Zhijiang Jinhu Wetland Park had declined due to the reduction in芡实 (water chestnut) cultivation. To address this, Jinhu implemented a scientific plan for planting floating aquatic plants, providing more “homes” for the Pheasant-tailed Jacana. Thesurvey observed 38 Pheasant-tailed Jacana in Jinhu, indicating a significant increase in their population.
According to reports, in 2023, birdwatching enthusiasts in Yichang observed a Blue-throated Bee-eater nest in the Huangbai River Wetland Park in Yiling District, Yichang, and witnessed the successful breeding of five chicks. This year, after observing the same area during the breeding season, birdwatching enthusiasts found 14 young birds, indicating a growing population of Blue-throated Bee-eaters.
An official from the Yichang Forestry and Horticulture Bureau stated that they willincrease the frequency of scientific monitoring in areas where rare summer migratory birds are found. Natural reserve management agencies will further optimize the breeding environment for summer migratory birds, enhance the quality of ecological restoration along the Yichang section of the Yangtze River, provide safe and comfortable habitats for more rare birds, and continue to promote ecologicalprotection efforts along the Yangtze River.
