Lifetime foraging patterns of the wandering albatross: Life on the move! Special issue: Charismatic marine mega-fauna
International audience Wandering albatrosses are large long-lived seabirds that inhabit the Southern Ocean. This species uses wind to move at low energetic costs and probably represents one of the best studied life-history models in animals. Here, using both tracking and isotopic data, we report on...

International audience Wandering albatrosses are large long-lived seabirds that inhabit the Southern Ocean. This species uses wind to move at low energetic costs and probably represents one of the best studied life-history models in animals. Here, using both tracking and isotopic data, we report on the lifetime distribution of wandering albatrosses at sea, constructing a synthesis about how their distribution, foraging movements and feeding ecology change throughout all life-history stages (i.e. juvenile, immature, pre breeding adults, breeding adults, sabbatical adults and senescent birds). Males and females exhibit different foraging strategies that change throughout their life. For instance, as males mature from young to old stages, they progressively move from subtropical waters to Antarctic waters. In comparison, females remain in subtropical waters throughout their lives, but increase their speed of travelwith age.
