Relying on the excellent research team of Tsinghua University, Department of Earth System Science(DESS)Tsinghua University Si Yali research group carried outancooperationresearchwith the Poyang Lake National Nature Reserve Administration Bureau. They carried out two satellite tracking workformigratory waterfowl respectively in February and December2015, in Jiangxi Province, Poyang Lake protected areas, in order to understand the migrationrulesand dynamic pattern of East Asiangeese under the influence ofenvironmental factor. Thesetwoworkssuccessfully captured and released 41 migratory waterbirds, including 4 white fronted GooseinFebruary 2015 and 37wildgooseinDecember 2015 (20white fronted Goose, 13bean gooseand 3 white fronted goose goose, 1swan goose) (Figure 1). The project aims to research the migration routesand rulesand important stopover sites, providing an important scientific basis for the Asian Waterbird Conservation and habitat protection and management.

By now, 22 data are recycled successfully. During thespringmigrationin 2016, 8 white fronted geese migrated with a distance around 5000km, and came back to propagation areas of buckled Delta and the Yana Bay in the end of May and the beginning of June (left panel in Figure2). And 7 out of 8 geese came back toPoyang Lake protected areasfor wintering successfully and all are in good condition. 6 white fronted geese were out of contact when they reached Nenjiang River Basin which is 2800 km away from wintering area.

At the same time, the research groupgot part of springmigration route of 7bean geese in 2016 (Figure 3), in Shandong, Qingdao (E011), Northeast (E024, H004, H019, H022, T012) respectively.AndinSevero-Evenskiy (E007), which isadjacent to the breeding ground, the data waslost,andE007 flight distanceis5700 km.
