Taxonomy

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. The species does undergo fluctuations, and over recent years the known wild population has ranged from c.325 to c.410 individuals, while the possible wild population has ranged from c.375 to c.490 individuals (N. Zuel in litt. 2017). It is tentatively assessed that the population size numbers >250 mature individuals, and so would fall in the range 250-999 mature individuals.

Trend justification: The population has been roughly stable since the early 2000s (C. Jones, V. Tatayah and N. Zuel in litt. 2017). The species does show population fluctuations, and it appears to be on one of the downward trends of these fluctuations currently. However, since exceeding 300 known individuals in the wild the population has never dipped below this figure with lows of c.325 individuals.
