The Plain flowerpecker, or Dicaeum minullum, is a diminutive bird, measuring a mere 9 centimeters in length. Exhibiting no significant sexual dimorphism, both male and female birds share a similar appearance.
To identify the Plain flowerpecker, one should look for its small stature and the lack of marked differences between the sexes. The subspecies found in northeastern India, Myanmar, Laos, and southern China, previously referred to as olivaceum, is now recognized as the same species, Dicaeum minullum, which also includes the population from Hainan Island.
This species thrives in subtropical or tropical moist lowland forests, where it can be observed living and foraging.
The Plain flowerpecker graces the central Himalayas, stretches across western Indonesia, and reaches as far as Taiwan, showcasing its adaptability across diverse regions.
Like its flowerpecker kin, this bird has a particular affinity for mistletoe, which it frequents for foraging purposes.
The IUCN has classified the Plain flowerpecker as Least Concern, indicating a stable population without immediate threats to its survival.
