Taxonomy

Taxonomic note

Ceyx cyanopectus and C. nigrirostris (del Hoyo and Collar 2014) were previously placed in the genus Alcedo and lumped as A. cyanopectus following Sibley and Monroe (1990, 1993), the gender agreement of which followed David and Gosselin (2002a).

Population justification: The population has not accurately been quantified, although the species appears to be quite rare (eBird 2022) with few records even from areas that are well surveyed and none from areas unforested. As an approximation, using densities of congeners and extents of suitable habitat along rivers and tributaries (Global Forest Watch 2022, using data from Hansen et al. [2013] and methods disclosed therein), each island is suspected of hosting no more than 500 pairs. There is, however, tremendous uncertainty with this and a robust, species-specific estimation should be considered a research priority. The global population is therefore suspected of numbering 1,000-2,499 mature individuals, with a best guess of 1,500. Each island is considered a separate subpopulation, although sites may now be so fragmented that multiple artificial subpopulations exist within these. Nonetheless, it is highly likely that no subpopulation exceeds 1,000 mature individuals. Further research is needed.

Trend justification: There are no robust data available on this species' trend. Nonetheless, it is suspected of declining because of ongoing (albeit low rates of) habitat loss and degradation (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein), fragmentation impacts and potentially riverine pollution.
