Taxonomic note

Ceyx argentatus and C. flumenicola (del Hoyo and Collar 2014) were previously placed in the genus Alcedo and lumped as A. argentata following Sibley and Monroe (1990, 1993).

Population justification: The population is estimated to number 2,500-9,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: Forest loss in the Philippines has been rapid and comprehensive. Remaining tracts of lowland forest with clear streams suitable for this species are under severe pressure and as a result it is suspected to be declining moderately rapidly.
