Résumé :	Records of the Sociable Lapwing Vanellus gregarius in western and central Europe were analysed. Sightings in these areas reached 20-21 per year in 2003-05, the most recent years for which complete data were available, with records from France, Spain and Portugal amounting to one-third of the European total during the decade 1996-2005. While most occurred in spring or autumn, records in the Iberian Peninsula were concentrated in the winter months. Spring movements appeared to be, on average, faster and to follow a more southerly route than those in autumn. Numbers reported were only slightly lower in spring than in autumn, suggesting that winter mortality rates may be low. In autumn, about 60% of birds that were aged were in juvenile/first-year plumage. The observed patterns, taking into account the numbers and distribution of observers and the species' habitat preferences, support the hypothesis that small numbers of Sociable Lapwings may winter regularly in Iberia.
