Population justification: The population in 2015 was 283 birds (including 137 on Frégate, 58 on Denis, 46 on Cousin, 32 on Cousine, and 10 on Aride) (Burt et al. 2016). This number is roughly equivalent to 190 mature individuals.

Trend justification: The total population was 86 birds in 2000 (Millet and Shah 2001), this had increased to 178 in 2006 (N. Shah in litt. 2005), indicating a population increase of more than 100% over six years, owing to intensive conservation efforts, and as of 2015 the population was 283 (Burt et al. 2016).
