Population justification: The known population in 2012 was 43-44 individuals (Blanvillain 2012), however the population size had increased to >50 individuals in 2014 (M. O'Brien and C. Blanvillain in litt. 2015). The number of mature individuals likely still remains within the band <50.
Trend justification: Since 2004, the species has shown signs of recovery, with new pairs becoming established in abandoned territories and recruitment of young birds in 2008 (Ghestemme in litt. 2012). The total population has increased slightly to 19 known individuals (40-45 estimated individuals) in 2006 (Gouni et al. 2007) and a known population of 40 individuals in 2011 (Ghestemme et al. 2011) and 43-44 in 2012 (Blanvillain 2012).
