The brown bush warbler is a songbird species. Formerly placed in the "Old World warbler" assemblage as Bradypterus luteoventrus, it is now placed in the newly recognized family Locustellidae.
Region
Himalayas and Southeast Asia
Typical Environment
Breeds across the central and eastern Himalayas through northeastern India, Nepal, Bhutan, and into northern Myanmar and southwestern China (e.g., Yunnan and adjacent ranges). It also occurs in upland areas of northern Indochina. In the non-breeding season it descends to lower elevations and spreads into foothill and adjacent lowland thickets. Typical habitats include dense bamboo, rhododendron scrub, forest edge, clearings, and secondary growth, often near damp gullies or streams.
Altitude Range
300–3200 m

The brown bush warbler is a shy, ground-loving songbird now placed in the grassbird family Locustellidae, having formerly been in the broad “Old World warbler” group as Bradypterus luteoventris. It is notorious for staying hidden in dense undergrowth and is more often heard than seen. Males deliver a persistent, insect-like reel from inside cover during the breeding season. It favors bamboo and rhododendron thickets and often shifts downslope in winter.
Temperament
solitary and secretive
Flight Pattern
short rapid wingbeats, low over cover
Social Behavior
Usually solitary or in pairs during the breeding season, holding dense, low territories. Nests are placed low in thick vegetation, often in bamboo or rank grass. Likely monogamous, with both parents involved in caring for the young.
Migratory Pattern
Seasonal migrant
Song Description
A sustained, insect-like reeling or buzzing trill delivered from deep cover or a low perch, often at dawn and dusk. The song is steady, simple, and can carry surprisingly far, while calls are soft ticks and tacks given from the undergrowth.
Plumage
Plain, warm brown above with slightly paler brown to buff underparts and a smooth, unpatterned look; tail long and graduated.
Diet
Feeds mainly on small invertebrates such as beetles, caterpillars, ants, spiders, and other arthropods. Forages by gleaning and probing among leaf litter, stems, and low tangles. It occasionally sallies a short distance to snatch prey but typically stays within a meter or two of the ground.
Preferred Environment
Dense undergrowth, bamboo, rhododendron thickets, and scrubby forest edges where it can remain concealed. Often keeps to shaded, moist microhabitats near streams or gullies.
