DESCRIPTION OF TAXONOMIC GROUP FOR EXPERT ASSESSMENT
There are approximately 60 species of seabirds known to breed in and around Australia and the external territories of Cocos (Keeling) and Christmas Island, Lord Howe and Norfolk Islands, Ashmore and Cartier Islands, and the Coral Sea islands. These species are comprised of penguins, albatrosses, petrels, shearwaters, prions, storm-petrels, boobies, tropicbirds, frigatebirds, cormorants, pelicans, gulls, terns and noddies.

DATA STREAM(S) USED IN EXPERT ASSESSMENT
The raw survey/census data are with the original investigators whose published materials were drawn on in Woehler and Baker (2020) and Garnett and Baker (in press) reviews. The 2021 assessment drew heavily on Woehler and Baker (2020) and references therein (c.150). The spatial extent comprises Australia and the external territories of Cocos (Keeling) and Christmas Island, Lord Howe and Norfolk Islands, Ashmore and Cartier Islands, and the Coral Sea islands. The temporal extent varies by species and/or study undertaken.

nil

Lineage Statement: QUALITY OF DATA USED IN THE ASSESSMENT This varies, as noted throughout the assessment. Some study populations have annual surveys while others are more episodic/opportunistic. The ASG workshop undertook an extensive literature compilation/review and expert solicitation to assess threats assessment (Woehler and Baker 2020). Species’ assessments in Garnett and Baker (in press) typically authored by investigators working on individual species, drawing on expertise and unpublished data. All other studies published in primary journals have been peer-reviewed.
