Typical Environment
Occurs in evergreen lowland and hill forests, forest edges, and well-wooded secondary growth on Java and Bali. It frequents flowering trees and tall shrubs, moving through the mid-story to canopy to follow blooms. The species also visits gardens and plantations with abundant nectar sources. It adapts to semi-disturbed habitats provided suitable flowering plants remain.

A long-billed nectar specialist, the streaky-breasted spiderhunter often perches to feed rather than hovering, using a brush-tipped tongue to probe tubular flowers. It also takes spiders and small insects, sometimes raiding spider webs—hence the name. Some authorities have treated it as conspecific with the grey-breasted spiderhunter, but most now recognize it as distinct and confined to Java and Bali.
Temperament
shy and active
Flight Pattern
short rapid wingbeats with direct, purposeful flight
Social Behavior
Usually seen singly or in pairs, moving methodically between flowering trees. Nests are suspended, pouch-like structures stitched with plant fibers and spider silk beneath large leaves. The species defends rich nectar sources but is otherwise inconspicuous within dense foliage.
Migratory Pattern
Resident
Song Description
Vocalizations are sharp, thin whistles and squeaky, repeated notes delivered from cover. Calls may accelerate into short series when agitated around feeding territories.
