Résumé :	Counts of Common Sterna hirundo and Arctic Terns S. paradisaea at Chew Valley Lake, Avon, are analysed over a 36-year period. These data are compared with counts from seawatching headlands on the south coast of England - at Portland and Dungeness - and also on the north coast of France, at Cap Griz Nez. This enables a comparison of the migration patterns of the two species and clarifies the likelihood of encountering either in southern England. Their identification is also revisited and the reliability of data from some areas is queried.[GRAPHICS].
