Description
Summary:Emperor penguin, foraging, diving, diet. - Emperor penguins are the largest living penguin and the only bird species that breeds during the Antarctic winter, on sea-ice around the Antarctic continent. They are fundamentally adapted to the high Antarctic sea-ice environment, showing radical breeding and foraging behaviour. High latitude-breeding exposes emperor penguins to extreme changes in sea-ice cover and light conditions over the course of the year, both factors that are likely to affect foraging success. This thesis examines some of the ecological and physiological constraints on emperor penguin foraging behaviour using birds from Pointe GÃ @Bremen, Univ., Diss., 2007
