Population justification: A combination of survey results and records (S. Parr in litt. 1999) can be used to deduce a total population of at least 800 individuals, roughly equivalent to 530 mature individuals.

Trend justification: Following surveys in 2002, the Mahé population was considered stable (Millett et al. 2003). Considerable development and habitat alteration have taken place on Mahé since 2002, suggesting that the population is unlikely to have increased since then, and may have decreased (N. Doak in litt. 2007). The Praslin population declined from around 20 pairs in the 1980s to just a few pairs in the 1990s, and four pairs in late 2002 (Rocamora 1997; Millett et al. 2003). Thus, overall the population is judged to have experienced a small decline over the last ten years.
