Population justification: The mainland population was estimated at 216-244 individuals in 2002, with a minimum of 108 breeding pairs, and the population was estimated to have remained at 108 pairs in 2012 (V. Tatayah in litt. 2012). This is roughly equivalent to 140-170 mature individuals. The latest population estimate for the mainland population in 2011-2014 is 240-330 individuals (V. Tatayah, C. Jones and N. Zuel in litt. 2015), equivalent to 160-220 mature individuals. It has since increased following the release of birds on Ile aux Aigrettes in 2006 with a total of 110 adults there in 2012 and an estimated 180-200 individuals in 2011-2014 (V. Tatayah, C. Jones and N. Zuel in litt. 2015). The pre-release population estimate will be retained until the population is confirmed to have sustained itself above 250 mature individuals for five years.

Trend justification: The population declined rapidly until the early 1990s since which time it has been stable or possibly increasing on the mainland (Cristinacce 2007, V. Tatayah in litt. 2011). Following translocations to Ile aux Aigrettes it increased but has since dropped and then stabilised; translocations to Round Island have so far been unsuccessful.
