Abstract
Knowledge of habitat use by top marine predators
in response to environmental conditions is crucial in the
current context of global changes occurring in the Southern
Ocean. We examined the at-sea locations of male Ade´lie
penguins (Pygoscelis adeliae) breeding at Dumont d’Urville
during their first, long incubation trip. Compared with the
chick-rearing period, penguins performed longer trips, going
to oceanic waters as far as 320 km from the colony. We
observed 3 strategies: (1) five individuals covered large distances
to the north, targeting open-ocean areas and following
the currents of two persistent eddies; (2) five individuals
foraged to the north-west, close to the Antarctic shelf slope at
the limit of the pack ice; and (3) three individuals covered
much shorter distances (northwards or eastwards). The foraging
range also seemed to be limited by the body condition
of the penguins before their departure to sea.
