Kleptoparasitism in foraging gentoo penguins Pygoscelis papua
An ongoing challenge in marine top predator research is understanding processes that are responsible for patterns that are often derived from land-based access to individuals. The use of animal-borne camera loggers, however, is proving useful in this regard as researchers can directly observe species and habitat-associated interactions. During an ongoing study investigating the foraging ecology of gentoo penguins (Pygoscelis papua) at the Falkland Islands, we observed the first attempted underwater intraspecific kleptoparasitism event for a penguin. This was revealed through a bird deployed with an animal-borne camera logger. Although unsuccessful in its attempt, the new reported behaviour highlights a novel interaction and further demonstrates the value of cameras in better understanding the ecology of marine vertebrates.
