ABSTRACTEvidence for the disturbance of king penguins (Aptenodytes patagonicus) and other seabirds at sub-Antarctic islands by fixed-wing aircraft making airdrops is reviewed. Based on direct observations of panicking birds at king penguin colonies at Marion Island as Lockheed C-130 Hercules aircraft flew past, it is postulated that the incident at Macquarie Island in 1990 when many king penguins were found dead shortly after a flypast was most likely caused by panic induced by the aircraft's passage. Visits by fixed-wing aircraft to sub-Antarctic islands should be kept to a minimum and no airstrips should be built on them. Specific recommendations are given for fixed-wing aircraft visits to Marion Island, in order to reduce disturbance to king penguins and other seabirds to the absolute minimum. These recommendations should be adopted at all sub-Antarctic islands.

AbstractIntroduced house miceMus musculusL. have been discovered to be major predators of chicks of the Tristan albatrossDiomedea dabbenenaL. and Atlantic petrelPterodroma incertaSchlegel and to also predate great shearwaterPuffinus gravisO'Reilly chicks at Gough Island, and similar predatory behaviour has been reported for house mice on Marion Island. Observations on Gough Island over three breeding seasons of nesting Atlantic yellow-nosed albatrossesThalassarche chlororhynchosGmelin and dark-mantled sooty albatrossPhoebetria fuscaHilsenberg indicate that house mice are also preying on these two species: the first records of mice preying upon summer-breeding albatross species on Gough Island. Predation on these two albatross species appears to be relatively rare (∼2% for the Atlantic yellow-nosed albatrosses) and ongoing monitoring is required to ascertain if the impact of mice is increasing. Conservation actions to eradicate mice from Gough Island will be of benefit to these species and other species that are being impacted by this invasive species.
