Observations of primary moult in adult Wood Sandpipers Tringa glareola on southward migration through east and central Europe

摘要: The pattern of moult in Wood Sandpipers Tringa glareola is not well described, due to the limited availability of data. It is generally considered that in the majority of adult Wood Sandpipers moult does not commence until they have reached their tropical or subtropical non-breeding destinations (Prater et al. 1977). There are, however, records of primary moult in Wood Sandpipers of Scandinavian origin starting close to the breeding grounds, during the early stage of southward
