Age, sex and breeding status shape a complex foraging pattern in an extremely long-lived seabird
International audience Evidence of age-dependent changes in foraging behavior of free-ranging individuals is scarce, especially at older stages. Using the isotopic niche as a proxy of the trophic niche during both the breeding (blood) and inter-nesting (feather) periods, we report here empirical evi...

International audience Evidence of age-dependent changes in foraging behavior of free-ranging individuals is scarce, especially at older stages. Using the isotopic niche as a proxy of the trophic niche during both the breeding (blood) and inter-nesting (feather) periods, we report here empirical evidence for age-, gender- and breeding status-dependent foraging ecology and examine its potential consequences on subsequent reproduction and survival in an extremely long-lived species, the wandering albatross.

In contrast to immature birds, adult females forage on average at northern latitudes than males, with both sexes feeding in the subtropics during the inter-nesting period, and males, not females, favouring subantartic waters during incubation.
