Population justification: The species has a large global population with an estimated minimum of 1,200,000 individuals (Delany and Scott 2006). In the Houtman Albrolhos, populations were estimated at 7,665, 6,325 and 34,895 pairs on Morley, Wooded and Pelsart Island respectively in 1993 (Higgins and Davies 1996).
Trend justification: The overall population trend is stable, although some populations have unknown trends (Delany and Scott 2006).
