Population justification: The population was estimated to comprise 7,920 pairs in 381 km2 on Basse-Terre, and 2,410 pairs in 135 km2 on Grande-Terre in 1994 (Villard and Rousteau 1998). Surveys in 2007 revealed no significant change, but a different methodology calculated a total population of 8,469 pairs (Villard et al. 2010). The population is therefore estimated to number at least 16,000 mature individuals, roughly equivalent to 24,000 individuals in total.

Trend justification: The population is stable (Villard et al. 2010). The population on Grande Terre is decreasing (G. van Laere in litt. 2016). On Basse Terre island, the National Park has performed an annual survey since 2009 based on the kilometric index method. This survey indicates an increasing trend (G. van Laere in litt. 2016).
