Among the nine global flyways, the East Asian-Australasian Flyway (EAAF) is the most threatened one. Over 15% of the migratory waterbirds are threatened. In particular to some geese species in which the populations showed drastic decline in the past 50 years. To get more ecological information about the geese on EAAF, which would then strengthen the conservation of these species, the EAAFP Secretariat Science Unit, Center for East Asian-Australasian Flyway (CEAAF) of Beijing Forestry University and Birds Data Technologies (Beijing) LLC. tracked Lesser White-fronted Goose (Anser erythropus), Greater white-fronted Goose (A. albifrons), Bean Goose (A. fablis), Common Goose (A. anser), and Swan Goose (A. cygnoides) on EAA Flyway. They obtained 33 complete migration routes of these 5 species. In this video, it shows the detailed migration patterns of these geese. This information filled the gaps of numerous key information, such as locations of their main breeding sites and key staging sites. The team will continue to conduct satellite tracking, in which the findings will help to improve the conservation and management, thus to provide a better flyway for these geese.

Summary in Chinese:

在全球九大迁飞区中，东亚-澳大利西亚迁飞区（The East Asian-Australasian Flyway，EAAF）是受胁最为严重的一条，超过15%的迁徙水鸟都受到不同程度的威胁，迁飞区上的雁类更是在过去50年间都表现出了显著下降趋势。为了增强对迁徙路线上雁类基础信息的了解，从而针对性地加强物种保护工作，东亚-澳大利西亚迁飞区伙伴协定秘书部科学部，北京林业大学东亚-澳大利西亚候鸟迁徙研究中心（CEAAF）联合百鸟数据科技（北京）有限责任公司对这条迁徙路线上的小白额雁（Anser erythropus）、白额雁（A. albifrons）、豆雁（A. fablis）、灰雁（A. anser）与鸿雁（A. cygnoides）进行了追踪实验，最终获取了33条完整的迁徙路线，详细地展现了雁类迁徙节律，填补了雁类的繁殖地、重要停歇地等重要信息空白。后续研究团队将会继续进行追踪实验，并将追踪结果应用到物种保护工作中，为迁徙路线上的雁类创造更多生机。
