The crescent-chested babbler is a babbler species in the family Timaliidae and is native to the Indonesian islands of Java and Bali. It inhabits subtropical or tropical moist lowland forest, montane forest and shrubland. It is listed as Least Concern on the IUCN Red List.
Region
Southeast Asia
Typical Environment
Endemic to the Indonesian islands of Java and Bali, it inhabits the understory of primary and secondary evergreen forests. It also uses forest edges, tall shrublands, bamboo thickets, and well-shaded plantations where dense cover persists. The species favors tangled vines and saplings where it can skulk and glean prey, and occasionally ventures into montane forest undergrowth. It is generally absent from highly degraded open areas.

Ease of Keeping
Beginner friendly: 1/5
This shy undergrowth specialist takes its name from the bold dark crescent across its upper chest. It forages close to the ground, often flicking leaves to glean insects, and sometimes joins mixed-species flocks. Pairs keep in contact with antiphonal duets, a hallmark of many babblers.
Temperament
secretive and active
Flight Pattern
short rapid wingbeats
Social Behavior
Typically found in pairs or small family groups, often maintaining close contact with soft calls. It frequently joins mixed-species flocks in the understory, especially while foraging. Nests are placed low in dense shrubs or saplings, with both parents involved in care.
Migratory Pattern
Resident
Song Description
A lively, musical series of whistles and chattering notes delivered in short phrases. Pairs often duet, with one bird answering the other in rapid succession. Alarm calls are sharper scolds from dense cover.
Plumage
Warm brown upperparts with slightly rufous wings and tail, paler buff underparts, and a contrasting dark crescent across the upper breast. Throat is paler, with fine facial patterning and subtle supercilium. Feathers appear soft and sleek, aiding a smooth, rounded outline in dense cover.
Diet
Primarily feeds on small insects and other arthropods such as beetles, caterpillars, ants, and spiders. It gleans from leaves, twigs, and vine tangles, and sometimes probes bark crevices. Occasionally, it may take small berries or seeds when insect prey is scarce.
Preferred Environment
Forages in the shaded understory and mid-scrub layers, typically within 1–3 meters of the ground. It favors dense, tangled vegetation along forest edges, clearings with regrowth, and bamboo growth where cover is abundant.
