Population justification: Following an estimate of 2,500 active pairs in 1991, the total number of mature individuals has been put at c.6,000, equating to c.9,000 individuals in total. It should be noted that only a proportion breed in a given year owing to a 15-18 month breeding cycle and the possibility that some unsuccessful pairs take 'rest years' rather than breed in successive years. Despite a helicopter survey in 2002, the 1991 survey is considered the most accurate and comprehensive.
Trend justification: The species's population is estimated to have declined by 30-49% over the last 90 years based on its disappearance from much of its former breeding range in the Indian and Pacific Oceans.
