Description
Summary:The objectives of the long-term study carried out in Admiralty Bay, King George Island, are to deepen our understanding of the individual breeding biology of the three Pygoscelis penguins that breed there and to determine how the annual fluctuations in their reproductive success reflect changes in the antarctic ecosystem (Trivelpiece et al. 1990b). The research carried out at the Copacabana field station had four main components: • to continue to monitor reproductive success of the Adélie (Pygoscelis adeliae), gentoo (P. papua), and chinstrap (P. antarctica) penguins, south polar and brown skuas (Catharacta maccormicki and C. Ionnbergi), southern giant petrels (Macronectes giganteus), kelp gulls (Larus dominicanus), and sheathbills (Chionis alba); • to examine foraging and diving behavior of Adélies and gentoos; • to examine band-loss rates in Ad(dies and gentoos; and • to sample the diets of all three Pygoscelids throughout the chick-rearing period.
