The datafile contains seasonal resighting histories of 538 adult Eurasian spoonbills that breed in the Netherlands or Germany and winter in France, Iberia or Mauritania, resighted between October 2005 and September 2012. Resighting periods are defined as October-December and January-March in an individual's wintering area and April-June and July-September in the breeding areas in The Netherlands and Germany. The resighting history of an individual starts with the first resighting as an adult (3rd winter or older) in its wintering region, being France, Iberia or Mauritania (and indicated in the column "group" of the datafile). Further details can be found in the Supplementary Material associated with the manuscript
