The importance of land-based prey for sympatrically breeding giant petrels at sub-Antarctic Marion Island

Northern (Macronectes halli) and southern (M. giganteus) giant petrels breed at different times at sub-Antarctic Marion Island. Long-term census and breeding success data are used to test for competitive overlap between the two species by correlating population trends with those of land-based prey/c...
