King penguin Aptenodytes patagonicus diving and breeding behavior in years with contrasting prey availability at South Georgia : State-dependent allocation of time, body mass and diving effort: Sub-optimal life-history decisions in King penguins
During three subsequent reproductive seasons with contrasting food availability, the King Penguin Aptenodytes patagonicus responses were monitored in a small colony at Husvik, South Georgia. Observations of metal flipper rings were complemented with transponder implants; automatically scaling and ti...

During three subsequent reproductive seasons with contrasting food availability, the King Penguin Aptenodytes patagonicus responses were monitored in a small colony at Husvik, South Georgia.

During the last season, poor food condition forced the birds to make state-dependent decisions that maximised foraging effort and squeezed time budgets, in order to maintain body mass.
