According to the IUCN, “Disease appears to be a problem in some populations in some years, with diphtheritic stomatitis (caused by the bacteria Corynebacterium spp.) and the blood parasite Leucocytozoon tawaki, formerly only known from Fiordland penguins, causes of mortality for chicks… Human disturbance, particularly from unregulated tourists at breeding areas, negatively affects energy budgets, fledgling weight and probability of survival.” “Yellow-Eyed Penguin, Megadyptes antipodes,” IUCN Red List of Threatened Species 2018, BirdLife International, 2018, http://dx.doi.org/10.2305/IUCN.UK.2018-2.RLTS.T22697800A132603494.en.
