2015-16 recommendations Gibson’s albatross: • Population size and trend and adult survival should continue to be estimated at regular intervals until the population substantially increases. • A detailed modelling exercise such as the one carried out by Francis et al in 2012 would give a better indication of the trajectory of the whole population and should be undertaken within the next five years. • Recent estimates of the size of the population are sufficiently accurate that a wole-island census is probably unnecessary. White-capped albatross: • [aerial photographs need to be counted] 29
White-chinned petrel • Resight data have been collected annually at the Auckland Islands since 2013 and monitoring should continue for the project to yield useful demographic data. Northern giant petrel • We recommend future monitoring of the Auckland Island Northern giant petrel breeding population. Ideally island-wide surveys would be repeated every three to five years. Enderby Island would be the ideal location for regular, annual counts of breeding birds. Disturbance from tourism may negatively impact upon breeding Northern giant petrels on Enderby Island, and should be monitored given that the island supports such a large proportion of the Auckland Island breeding population. • Because there are no trend data for Northern giant petrels anywhere in the NZ region, we strongly advise that the Antipodes and Campbell Islands populations are re-counted in the near future and the results related to previous counts (Wiltshire and Scofield 2000; Wiltshire and Hamilton 2000) 30
