The early life of king penguins: ontogeny of dive capacity and foraging behaviour in an expert diver
International audience The period of emancipation, when juvenile seabirds change from a terrestrial existence to a life at sea, is associated with many challenges. Apart from finding favourable foraging sites, they have to develop effective prey search patterns and physiological capacities that enab...

To investigate the ontogeny of their dive capacity and foraging performance, we implanted juvenile king penguins before their first departure to sea and also adult breeders with a data-logger recording pressure and temperature. We found that juvenile king penguins possessed a remarkable dive capacity when leaving their natal colony, enabling them to conduct dives in access of 100 m within their first week at sea.

A significantly shallower foraging depth of juveniles, particularly during their first five months at sea, could also indicate differences in foraging strategy and targeted prey. The initially greater wiggle rate suggests that juveniles fed opportunistically and also targeted different prey than adults and/or that many wiggles of juveniles reflect unsuccessful prey-capture attempts, indicating a lower foraging proficiency. After five months, this difference disappeared, suggesting sufficient physical maturation and improvement of juvenile foraging skills.
