Recommended Management Actions
    Investigate the dispersal of Tahiti Petrels between and the South Pacific Ocean breeding island and Australia
    Investigate the providence of the Tahiti Petrels that occur of the northwest coast of Western Australia in the Indian Ocean

      Gain an improved understanding of the at sea distribution in Australia

      Determine non-breeding areas and migration routes

      Work with range states to control, or eradicate invasive species on breeding islands

    Work with range states to manage the impact of extractive industries on breeding islands

Kerguelen Petrel (Lugensa brevirostris)

Life History and Distribution
The Kerguelen Petrel (Lugensa brevirostris also known as Aphrodroma brevirostris) is a medium-sized all-dark petrel of the Southern Ocean, similar in size to Soft-plumaged Petrel (Pterodroma mollis). The species has a very large circumpolar range in subantarctic and Antarctic waters. Kerguelen Petrel breeding colonies are present on Gough Island (St Helena to UK) in the Atlantic Ocean, and Marion Island and Prince Edward Island (South Africa), and Crozet Islands and Kerguelen Island (French Southern Territories) in the Indian Ocean. Its breeding season starts in August, forming loose colonies near the sea on marshy ground, and also higher up on volcanic ridges up to 450 m Above Sea Level (ASL). It nests in deep burrows dug in soft, wet soil (del Hoyo et al. 1992). Outside the breeding season its range is circumpolar, frequenting Australian waters south to the ice pack (del Hoyo et al. 1992). It feeds mostly on squid, but also krill and fish. Squid are captured by surface-seizing at night, but dipping is also seen.

Population Estimates and Trends
Brooke (2004) estimated that the global population numbers around 1 million individuals. The population is suspected to be decreasing, as invasive House Mice (Mus musculus) may be affecting breeding success.

Conservation Concerns and Actions
On Gough Island, one of the locations where this species is known to breed, mice are responsible for reduced breeding success of burrowing petrel species (Cuthbert et al. 2013). While the effects on this species specifically have not been investigated it is also likely to be negatively affected.

Recommended Management Actions

White-headed Petrel (Pterodroma lessonii)

Life History and Distribution
The White-headed Petrel (Pterodroma lessonii) is a large, solidly built all grey-white petrel. At sea the prominent black patch underscoring eye on an otherwise largely white head is diagnostic. The White-headed Petrel is oceanic, rarely approaching land except near colonies, but has been
