The Black-belted flowerpecker was once considered a subspecies of Red-keeled flowerpecker but has since been classified as a separate species

Feeds on small fruits, mistletoes, flowers and also takes small insects. Forages mostly in the canopy and middle stratum. Found singly, in pairs or mixed species flocks with other flowerpeckers and small birds. Breeding has been observed from April to August but . Relative to how common this species is, not much is actually known about this bird's biology.^[2]

This species is extremely adaptable to almost any habitat except montane forest, found in lowland forest, second growth, agricultural areas and parks. The IUCN has classified the species as least concern as it is common throughout its wide range. Its adaptability to be able to thrive in degraded habitat has made one of the few Philippine endemic birds that does not have a declining population.^[1]
