Taxonomic note
Ramphiculus fischeri was previously split as R. fischeri and R. meridionalis (del Hoyo and Collar 2014), prior to which they were previously placed in the genus Ptilinopus and lumped as P. fischeri following Sibley and Monroe (1990, 1993). Taxon meridionalis differs in its dark slate-grey vs dull emerald-green wing-coverts, secondaries, tertials, back and rump (3); mantle as dark grey as rest of wings and back vs whitish-grey shading to mid-grey before shading to the green of the upper back (ns1); white vs yellowish-white chin and upper throat (ns1); breast to mid-belly greyish-white vs mid-grey (2); mid-belly to vent greyish-white vs dull yellowish-grey (2). However, the form centralis sits between these two extremes and is intermediate in plumage, suggesting that differences may be clinal, and there is no indication of any vocal difference, so for now meridionalis is returned to a subspecies of R. fischeri. Formerly placed in genus Leucotreron. Closely allied to R. occipitalis. Three subspecies recognized.

Population justification: The global population size has not been quantified, but the species is described as uncommon (Gibbs et al. 2001, Eaton et al. 2021).
Trend justification: Much of this species' range lies above the altitudes where forest loss is occurring, and remote sensing data indicates that tree cover loss is ongoing slowly at a rate equivalent to 3-4% in three generations (Global Forest Watch 2023 using data from Hansen et al. [2013] and methods disclosed therein). The environs of the Lompobattang massif are one of the most densely populated areas of Sulawesi and all forest below 1,000-1,500 m, and locally up to 1,700 m, has disappeared as a result of land clearance for transmigration settlements, commercial logging and both shifting and plantation agriculture, affecting subspecies meridionalis. Remaining forest continues to be threatened by human activities. However, records from recently logged forest (eBird 2023) suggest this species may be relatively adaptable and less seriously threatened by logging activities than many forest birds (del Hoyo et al. 2022). Precautionarily therefore, the species is suspected to be declining slowly as a result of ongoing forest loss, although the rate has not been quantified.
