This proposal will continue a comparative study of the population               biology and ecology of Adelie, Gentoo, and Chinstrap penguins at                Admiralty Bay, King George Island, South shetland Islands, Antarctica           (62 10'S, 58 30'W).  The primary objective is to determine age-specific         demographic parameters for sympatric populations of Pygoscelis penguins,        and to compare these parameters between Adelie populations in different         environments.  Another objective is to compare the foraging                     behavior/ecology of the three species, and within each, to compare the          feeding proficiency of young, inexperienced, firts-time breeders with           older, established breeders.  Results from the latter effort should help        to explain patterns observed in the demographic data.  Pygoscelis               penguins are major predators of krill (Euphausia superba); these                predators and their prey are major components of the antarctic marine           food web.  To thoroughly understand the structure and function of the           Antarctic ecosystem, important information not yet available would be           the factors that drive age structure and regulate population size of key        trophic-level predators (penguins).  Such information will result from          the proposed study.
