Résumé :	The first underwater digital photographs obtained by cameras carried by Shags Phalacrocorax aristotelis showed the birds diving in areas dominated by soft coral Alcyonium digitatum and feeding on butterfish Pholis gunnellus, which were brought to the surface before being swallowed. Prey capture rates were markedly lower than previous estimates for birds feeding on sandeels Ammodytes. This reduced foraging performance probably contributed to the very poor breeding success at the colony on the Isle of May in 2005.
