Clements separates the pool taxon Picus fuliginosus as Mulleripicus fuliginosus, the Southern Sooty Woodpecker, from the northern species. The southern Philippine form is described as paler, with a distinct red facial patch in males and larger white spots.
A 2011 comparison describes southern fuliginosus males as having red confined to the submoustachial streak; the form is paler than northern birds and has larger white spots on the chin, throat, and neck.
The species profile associates it with forest and dense habitats and records an invertebrate diet.
An extinction-risk assessment has not been added yet.
