Population justification:
From their at-sea counts, Attie et al. (1997) suggest that the population may be around 1,000 individuals, implying 250 (45-400) breeding pairs, although 50-100 pairs was considered more likely (V. Bretagnolle in litt. 1999), i.e. 100-200 mature individuals. However, recent estimates indicate that the breeding population may be just a few dozen pairs (Tatayah et al. 2011). The recent sighting of 33 different individuals in three days at sea south of La Réunion suggests that a more likely breeding population size is 100 pairs (Shirihai et al. 2014).
Trend justification: The species is believed to be declining owing to predation and light-induced mortality.
