Taxonomy

Taxonomic note
Chrysocolaptes lucidus, C. guttacristatus, C. stricklandi, C. strictus, C. haematribon, C. erythrocephalus and C. xanthocephalus (del Hoyo and Collar 2014) were previously lumped as C. lucidus following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified owing to recent taxonomic splits, but given the small range and lack of recent records there may well be fewer than 10,000 mature individuals: a preliminary estimate therefore places the population within the band 2,500-9,999 mature individuals.

Trend justification: The population is suspected to be decreasing owing to ongoing habitat loss and degradation, particularly at lower altitudes.
