About Dicaeum minullum Swinhoe, 1870
This species, Dicaeum minullum Swinhoe, 1870, is made up of tiny birds measuring 9 cm in length, with no marked size or appearance difference between males and females. The subspecies found in northeastern India, whose range extends into Myanmar, Laos and southern China, was called olivaceum by earlier authors. Pamela C. Rasmussen treats this taxon as a separate species, Dicaeum minullum; this species includes the minullum population from Hainan Island, and is now referred to as the plain flowerpecker in a more restricted taxonomic sense. Its natural habitat is subtropical or tropical moist lowland forests. Like many other flowerpeckers, it prefers to forage on mistletoe.
