The Bornean bulbul is a member of the bulbul family of passerine birds. It is endemic to the island of Borneo.
Region
Borneo
Typical Environment
Occurs across much of Borneo in lowland and hill country, using forest edges, secondary forest, overgrown clearings, and riverine woodland. It adapts well to disturbed habitats provided fruiting shrubs and trees are present. Birds forage from understory to mid-canopy, often along forest margins and sunny gaps. It is less common in dense primary interiors than at edges and in mosaic habitats.

The Bornean bulbul is endemic to the island of Borneo, where it frequents forest edges, secondary growth, and gardens near woodland. It was formerly treated as part of a wider black-capped/black-crested bulbul complex but is now recognized as a distinct species by major checklists. It often joins mixed-species flocks and is an important disperser of native fruiting plants.
Temperament
social and active
Flight Pattern
short rapid wingbeats with brief glides
Social Behavior
Usually seen in pairs or small, loose groups, and commonly associates with mixed-species flocks while foraging. Builds a small cup nest in shrubs or low trees; both parents share incubation and chick-rearing duties. Territorial during the breeding season but tolerant of neighbors at good food sources.
Migratory Pattern
Resident
Song Description
A lively series of clear, fluty whistles interspersed with chattering notes. Calls are sharp and contact-oriented, while the song is more melodious and variable, delivered from elevated perches.
Plumage
Mostly olive-brown above with paler, yellow-washed underparts and a clean, neat look typical of bulbuls. The throat and breast are lighter, with slightly warmer yellow on the belly and vent. Feathers appear smooth and unspotted, giving a sleek, uniform impression.
Diet
Consumes a wide variety of small fruits and berries, including figs and other native fruiting trees. Supplements its diet with insects, caterpillars, and other small arthropods, especially when feeding young. Occasionally takes nectar or soft plant material. Plays a role in seed dispersal through frugivory.
Preferred Environment
Forages along forest edges, in scrubby secondary growth, and in mid-story foliage where fruiting shrubs are abundant. Also visits gardens and plantations that retain native trees and hedgerows.
