Population justification: There is no population density or estimate for this species. Approximately c.7,500 km2 of forest is thought to remain within its range (Global Forest Watch 2023, using data from Hansen et al. [2013] and methods disclosed therein). eBird (2023) data suggest that this species occurs in suitable habitat at a density not dissimilar to other flamebacks; C. stricklandi of Sri Lanka occurs at densities of c.5 individuals/km2 (Wijesundaral and Wijesundaral 2014). It is, however, notably commoner than Chrysocolaptes erythrocephalus (Allen 2020, eBird 2023). Assuming it occurs at a density of 2.5–7.5 birds/km2, and that c.50% of forest habitat in its range is occupied (excluding areas that are <1km2 in size), the population size is likely to be number c.9,400-28,000 birds, or 6,600-20,000 mature individuals.
Trend justification: Remote sensing data (Global Forest Watch 2023, using data from Hansen et al. [2013] and methods disclosed therein) indicate that over the past three generations (11.3 years; Bird et al. 2020) forest loss in this species' range has been equivalent to 11-14%, however this increased to an equivalent rate of c.20% over three generations between 2016 and 2021. As a forest dependent species, D. everetti is suspected to decline at a rate at least equal to that of forest loss and may additionally be impacted by fragmentation and selective logging of larger trees needed for nesting. With an increasing human population (PSA 2015) and few areas of lowland forest lying in protected areas, this rate is not expected to slow or cease in the future. It is therefore suspected to decline at a rate of 20-29% over the next three generations.
