Abstract
In 1991 and 1992 Common and Arctic Terns differed in chick-feeding and chick-rearing strategies. Arctic Terns favoured smaller prey, primarily crustaceans, for feeding their chicks than did Common Terns. Consequently, Arctic Tern feeding rates were higher. The influence of the tide on food parameters was greater in Arctic Terns. In both years breeding success was better in Common Terns.
