King penguins adjust foraging effort rather than diet when faced with poor foraging conditions
International audience The links between foraging success, foraging effort and diet in a myctophid specialist seabird, the King Penguin Aptenodytes patagonicus, were investigated during seven breeding seasons using tracking and isotopic data. Despite the variable foraging conditions encountered by t...
