Download AEBR 243 Modelling marine habitat utilisation by yellow-eyed penguins along their mainland distribution: baseline information

Using GPS tracking data obtained from yellow-eyed penguins since 2003, habitat models using the maximum entropy method were developed. Main factors determining habitat use were bathymetry, seafloor sediment composition, and colony distance. Acceptable model outputs were generated for North Otago and the Otago Peninsula as well as northern Stewart Island and Codfish Island. No adequate data were available for the Catlins, the eastern Foveaux Strait region, and southern Stewart Island; extrapolation from other regions proved unreliable. Habitat use maps are presented.
