1. A bioenergetics model assessment of the prey consumption of Adélie penguins in Subarea 48.1 and 48.2

   Island, South Orkneys. We show that the highest levels of consumption occur during the crèche and pre ... -moult period, consistent with similar studies of Adélie penguins breeding in East Antarctica. On the ... basis of variable breeding success and the proportion of krill and fish in their diet, we estimate that ... the population of Adélie penguins at Signy Island consumes 4,600 t of krill and 696 t of fish during a ...
