The Sumatran bulbul is a species of songbird in the bulbul family, Pycnonotidae. It is endemic to Sumatra (Indonesia).
Region
Southeast Asia
Typical Environment
Occurs across Sumatra’s hill and lower montane evergreen forests, including forest edges and secondary growth near mature forest. It is most often found in the midstory and canopy, where it moves through fruiting trees and dense foliage. The species tolerates lightly disturbed habitats and follows ridgelines and forested valleys. It is typically absent from open lowlands far from forest cover.
Altitude Range
300–2000 m

The Sumatran bulbul is a forest songbird endemic to the island of Sumatra in Indonesia. It was formerly treated as conspecific with the Sunda (Javan) bulbul but is now recognized as a separate species. By consuming and dispersing fruits, it plays a small yet important role in maintaining forest regeneration. It frequents fruiting trees and often joins mixed-species flocks in the midstory.
Temperament
social and active
Flight Pattern
short rapid wingbeats with brief glides
Social Behavior
Usually seen in pairs or small family groups and often joins mixed-species flocks moving through the canopy. It forms monogamous pairs during the breeding season. Nests are shallow cup structures placed in shrubs or small trees, with both parents participating in care.
Migratory Pattern
Resident
Song Description
Song is a series of clear, whistled phrases interspersed with chatters and trills. Calls include sharp contact notes and soft chups used to keep in touch while foraging.
Plumage
Olive-brown upperparts with a slightly darker crown and nape, paler grayish-olive underparts, and a whitish throat that may show faint streaking. Feathers are soft and slightly loose, often giving a subtly crested look on the crown. Underparts can show a warm wash toward the vent.
Diet
Primarily eats small fruits and berries, especially figs and other soft, pulpy species. Supplements diet with insects such as beetles, caterpillars, and small orthopterans gleaned from foliage. Occasionally sips nectar and takes arthropods flushed by mixed flocks.
Preferred Environment
Feeds in the midstory to canopy at fruiting trees along forest edges, ridges, and gaps. Also forages in secondary growth and along trails where fruiting shrubs are accessible.
