Abundance estimation of Adélie penguins colony at Esperanza/Hope Bay

We conducted a whole-colony census of the Adélie penguin colony at Esperanza/ Hope Bay. We also update breeding population data for selected breeding groups recorded consistently from 1995/96 to 2012/13. Both the whole colony and the selected breeding groups exhibit population declines, similar to what has been observed in other colonies throughout the WAP. The assessment of this population will contribute to the estimate of total predator biomass in Area 48.
