近日,，被譽為“鳥中國寶”的東方白鸛時隔10年再次現(xiàn)身松雅湖，“鳥中活化石”中華秋沙鴨的蹤跡時隔5年再次被觀鳥者觀測記錄,。與之相伴的,，是每年如期而至的天鵝群，還有白鶴,、黃眉鹀,、黃喉鹀,、紅尾斑鶇……

Recently, the Oriental Stork, renowned as the "national treasure of birds", reappeared at Songya Lake after an absence of 10 years. Meanwhile, the traces of the Scaly-sided Merganser, the "living fossil of birds", were once again observed and recorded by birdwatchers after a lapse of 5 years. Along with them were the swan flocks that arrive punctually every year, as well as the Siberian Crane, Yellow-browed Bunting, Yellow-throated Bunting, and Red-tailed Thrush.

東方白鸛和中華秋沙鴨是大型候鳥，在《世界自然保護聯(lián)盟瀕危物種紅色名錄》中屬于瀕危（EN）等級,，均被列入了中國一級重點保護野生動物名錄,。

The Oriental Stork and the Scaly-sided Merganser are large migratory birds. They are categorized as Endangered (EN) on the IUCN Red List of Threatened Species and have both been incorporated into the list of China's first-class protected wild animals.

省生物多樣性保護中心專家介紹， 東方白鸛,、中華秋沙鴨對棲息環(huán)境特別是水質(zhì)要求十分苛刻,，一旦水域被污染，它們就會立即離開,。這樣的生活習性導(dǎo)致東方白鸛,、中華秋沙鴨種群數(shù)量稀少，也使它們被視為典型的生態(tài)指示物種,。此次東方白鸛,、中華秋沙鴨的回歸，也為松雅湖的生物多樣性保護工作注入了新動力,。

Experts from the Hunan Biodiversity Conservation Center stated that the Oriental Stork and the Scaly-sided Merganser are highly demanding in terms of their habitats, especially the water quality. Once the water area is contaminated, they will depart promptly. Such living habits have resulted in the sparse populations of the Oriental Stork and the Scaly-sided Merganser and have also led to their being regarded as typical ecological indicator species. The return of the Oriental Stork and the Scaly-sided Merganser this time has also infused new impetus into the biodiversity conservation efforts at Songya Lake.
