1.The foraging ecology of emperor penguins was examined at two colonies on the Mawson Coast of Antarctica during the winter, spring and summer of 1988. The study sought to quantify the penguin's reproductive performances and chick mortality schedules, chick diet composition, energy intake and food consumption of adults and chicks, and adult hunting performance during the period of chick care. 2. Several techniques commonly used for conducting ecological research on penguins were modified for use on emperors. These included techniques for: capture and restraint, measuring body masses, marking individuals for identification, sampling stomach contents, preventing liquid radio-isotopes from freezing in sub zero temperatures, handling adults during incubation and brooding, withdrawing blood samples and attaching dive recorders. The techniques are of particular relevance to field research conducted during the Antarctic winter. 3. The population size and breeding success of emperor penguins at the Auster and Taylor ...
