Taxonomic note

Nesoenas picturata and N. rostrata (del Hoyo and Collar 2014) were previously lumped as N. picturata following Cheke (2005), and before that N. picturata and N. mayeri were present in the genus Streptopelia following Johnson et al. (2001), and before that were present in the genus Columba following Sibley and Monroe (1990, 1993).

Population justification: Jones et al. (2013) estimated the population to number 370-380 individuals in total, roughly equating to 240-255 mature individuals.

Trend justification: Survey results indicate that the population continues to fluctuate. Two sub-populations are currently declining, two increasing, and one stable. The overall trend is estimated to be a decline of 10-19% over ten years, which is ongoing.
