Dongtai-Rudong region borders the southern Yellow Sea. In autumn many shorebirds will gather in the arctic north and migrate south to spend their non-breeding seaon in south China, southeast Aisa, Australia and New Zealand. Some species stop here briefly, while others use the Dongtai-Rudong region as a key staging site to complete their annual wing/tail/body moult. The ones doing the full moult here include Spoon-billed Sandpiper and Nordmann's Greenshank. Thus in September and October we have the best chance to get large counts as moulting takes more than one month. The best formal population estimate of Spoon-billed Sandpiper is based on the counts in Dongtai-Rudong and for several years our counts of Nordmann's Greenshank exceed their current population estimate.

LianYunGang supports thousands of Asian Dowitchers regularly. Although peak time in southward migration is in August, in early September we can still see quite a few. Decent number of Relict Gull winter here and we may encounter a few immature birds.
