AbstractSeabird diets are generally composed of a few major taxa such as pelagic fish, squid and crustaceans (Shealer 2002), with small pelagic fish being the main foraging resource in temperate regions (Furness & Monaghan 1987). This is also true for the critically endangered Balearic Shearwater Puffinus mauretanicus. Its diet includes small pelagic fish and demersal fish obtained from trawling discards (Gutiérrez & Figuerola 1995, Arcos & Oro 2002, Louzao et al. 2006b, Käkelä et al. 2010). Direct observations at sea determined that this species also feeds on plankton, although the species of plankton have not been identified (Arcos et al. 2000, Arcos & Oro 2002). In this study, we report observations that, during breeding season, the diet of the endemic Balearic Shearwater includes macrozooplankton, specifically the krill Nyctiphanes couchii
