Abstract We compared systematic and random survey techniques to estimate breeding population sizes of burrow-nesting petrel species on Marion Island. White-chinned ( Procellaria aequinoctialis ) and blue ( Halobaena caerulea ) petrel population sizes were estimated in systematic surveys (which attem...
