Described on Ebird as "A small bird of forest and edge from the lowlands to low elevations in the mountains on Luzon and Catanduanes.

Similar to Olive-backed Sunbird, but has a red chest spot, an orange wash on the upper belly, and no white outer tail feathers.

Voice includes a high-pitched double-noted call, “chik-chik!”[2] It was previously conspecific with the Maroon-naped sunbird but it differs in molecular genetics, a less glossy crown, the a greenih instead of maroon nape and duller yellow belly.

Typically seen alone or in pairs but also joins mixed-species flocks [3] Its natural habitat is moist tropical primary and secondary forest up to 1,350 meters above sea level.

However, the population is believed to be declining due to deforestation from land conversion, Illegal logging and slash-and-burn farming.
