climate change
      Examine the relationship between foraging and breeding succuss, population density and productivity and surrounding sea including tracking to determine use of marine habitat in space and time
           Manage key sites to retain their value under climate change
           Regularly monitor breeding populations at index locations
           Determine non-breeding areas and migration routes
           Measure contaminant levels in all relevant life stages
           Work with range states to control, or eradicate invasive species on breeding islands
      Implement best practice quarantine measures at breeding colonies to reduce the risk of any invasive species (re)establishing on islands
           Establish new breeding colonies within former range

Tahiti Petrel (Pseudobulweria rostrata)

Life History and Distribution
The Tahiti Petrel (Pseudobulweria rostrata) is a medium-sized dark-brown and white petrel with a sharply demarcated dark hood. The species is found over warm, tropical and subtropical water in the Pacific Ocean. The species breeds in the Marquesas, Society and Gambier Islands, French Polynesia, Fiji, American Samoa and New Caledonia (to France). It used to breed in Vanuatu (BirdLife International 2019) and may breed on Rarotonga, Cook Islands (Pratt et al. 1987), as well as on other islands. Two subspecies are distinguished: trouessarti in New Caledonia and rostrata in French Polynesia, the subspecific status of birds from other archipelagos remaining unclear, although Brooke (2004) assigned them to rostrata. This distinction is poorly supported by morphological (Villard et al. 2006) and genetic (Gangloff et al. 2012) data, and detailed analyses of vocalization differences between the two subspecies are missing. The Tahiti Petrel occurs predominantly off southeast Queensland and Northeast NSW in spring through to early autumn with numbers peaking with the arrival of juveniles in December. In some years, small numbers of these petrels remain off the eastern Australian coast. Of interest is the occurrence of this species off the northwest coast. It is not known where these petrels have originated from Pacific Island population; an unknown population breeding in Indonesia; or an unknown population breeding in the Indian Ocean. The species generally nests at high altitudes within forest or scrub on mountain steep slopes or rims and craters of volcanic islands, but also on low coralline or rocky hill islets and backshore. Eggs are laid in burrows or cavities located underneath large rocks, within cliffs or rocky boulders, or among large tree root systems. Birds generally nest in loose and small colonies. Breeding appears to occur throughout the year, although at least on Tahiti, there appears to be a peak between March and July (Villard et al. 2006). In the non-breeding season, the species disperses widely, and birds have been recorded as far east as the coast
