Résumé :	To assess whether increasing numbers of Siberian vagrants observed in Europe in recent autumns can be linked to climate change, we predicted changes in the climatic suitability of the breeding ranges of 46 Siberian bird species known to show vagrancy to Europe and compared these predictions with observed changes in recorded rates of autumn vagrancy across eight European countries during the last three decades. There was a positive correlation between predicted increase in breeding range and vagrancy rates. A positive impact of climate change on range and population size could promote vagrancy, while the increasing use of such alternative migration flyways could provide adaptive advantages in a changing environment.
