Determining the migration routes and connections of migratory birds at the population level helps clarify intraspecific differences in migration.Five subspecies have been recognized in the Whimbrel(Numenius phaeopus)in Eurasia.Ssp.rogachevae is the most recently described subspecies.It breeds in Central Siberia,while its non-breeding region and migration routes are still unclear.We tracked the migration of Eurasian Whimbrels captured at three non-breeding sites(Moreton Bay in east coast of Australia,Roebuck Bay in Northwest Australia and Sungei Buloh Wetland in Singapore)and two migration stopover sites(Chongming Dongtan and Mai Po Wetland in China).We determined the breeding sites and inferred the subspecies of the tagged birds in the East Asian-Australasian Flyway(EAAF)based on the known breeding distribution of each subspecies.Of the 30 tagged birds,6 and 21 birds bred in the breeding range of ssp.rogachevae and variegatus,respectively;one bred in the presumed transition area between the breeding range of ssp.phaeopus and rogachevae,and two bred in the region between the breeding range of ssp.rogachevae and variegatus.The birds that bred in the ssp.rogachevae breeding range spent their non-breeding season in the northern Sumatra,Singapore,East Java and Northwest Australia and mainly stopped over along China's coasts during migration.None of our birds bred in the exclusive breeding range of the phaeopus subspecies.Previous studies have predicted that rogachevae whimbrels migrate along the Central Asian Flyway and spend the non-breeding season in West India and East Africa.We found that at least some rogachevae whimbrels migrate along the EAAF and spend the non-breeding season in Southeast Asia and Australia.The ssp.phaeopus is at best sparsely distributed in the EAAF in the west region,or possibly does not occur at all.
