Western mountain greenbul may refer to several species of birds, including:Olive-breasted greenbul, found in eastern and central Africa Western greenbul, found in west-central Africa
Region
West-Central Africa
Typical Environment
Occurs in montane and submontane evergreen forest, forest edges, and tall secondary growth with dense understory. It favors vine tangles, bamboo patches, and canopy gaps where fruiting trees and arthropods are abundant. Birds typically remain within forest strata from understory to mid-canopy, moving methodically through foliage. Habitat loss from logging and agriculture can reduce local occupancy, but the species complex persists in several protected highland blocks.
Altitude Range
800–2800 m

The name Western mountain greenbul has been used for more than one African montane bulbul, including the Western greenbul and the olive-breasted greenbul. These are inconspicuous, foliage-loving songbirds of high-elevation forests where they forage for fruit and insects. They are often detected by their ringing, chattering calls rather than by sight. Vocal differences and subtle plumage cues are important for separating similar species in this group.
Temperament
shy and skulking
Flight Pattern
short rapid wingbeats
Social Behavior
Often forages as pairs or in small family groups and readily joins mixed-species flocks in montane forest. Nesting is typically in a small, neatly built cup placed in dense vegetation. Likely monogamous with both parents contributing to care. Territorial songs and calls carry through forest ravines.
Migratory Pattern
Resident
Song Description
A series of bright, ringing notes and chatters delivered in short phrases, often repeated from a concealed perch. Contact calls are sharp chips or tiks used to keep pairs in touch within dense foliage.
Plumage
Soft, olive-green upperparts with yellow-olive underparts and a slightly greyer head and throat; plumage appears plain with faint mottling in some individuals.
Diet
Feeds on small fruits and berries as well as a wide range of arthropods, gleaned from leaves and twigs. Will sally short distances to snatch flying insects and probe clusters of dead leaves. Seasonal fruiting events can concentrate birds at certain trees. Opportunistic and adaptable within forested habitats.
Preferred Environment
Forages in understory to mid-canopy, especially along edges, gaps, and stream gullies where insect prey is abundant. Also uses secondary growth and overgrown clearings adjacent to primary forest.
