Description
Summary:Critically Endangered Spoon-billed Sandpipers Calidris pygmaea migrate from their breeding grounds in arctic and subarctic Russia along the East Asian-Australasian Flyway to winter in coastal habitats in south-east Asia. To describe the use of migration stopover and wintering sites during the post-breeding migration, we tracked six adults equipped with solar-powered Platform Transmitting Terminals (PTTs) on the breeding grounds and a further seven adults tagged at a post-breeding moulting site in Jiangsu Province, China. We identified 28 clusters of sites in all, of which nine appeared to be of special importance for refuelling for onward migration, or the post-breeding moult of flight feathers. In particular, we identified three sites in Russia that were used by tagged birds for prolonged periods of time prior to long migratory movements to the moulting grounds (Perevalochni Bay, Moroshechnaya River and Tyk Bay), three sites used during the period of flight feather moult (Rongmae Mudflat in DPRK; Tiaozini ...
