The chestnut-crowned bush warbler is a species of warbler found in South Asia. Although overall population size has not been quantified, this is one of the species that is declining due to habitat destruction. Although its population trend is observed to be decreasing, its decline is not happening in rapid fashion. For this reason, this is evaluated as least concern species.
Region
Himalayas and adjacent South Asia
Typical Environment
Primarily inhabits dense undergrowth in montane forests, thickets, bamboo, and rhododendron scrub from the central and eastern Himalayas eastward into adjacent uplands. Occurs from Nepal and Bhutan through northeastern India and northern Myanmar, with some populations reaching into southwestern China. Breeds in cool, moist slopes with thick ground cover and moves downslope to similar dense habitats in winter. Prefers areas with tangled vegetation near forest edges, clearings, and ravines.
Altitude Range
800–3200 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
A shy skulk of the Himalayan undergrowth, the chestnut-crowned bush warbler keeps low in dense shrubs and bamboo, often revealing itself only by its loud, ringing song. It undertakes local altitudinal movements, breeding higher on cool, brushy slopes and descending in winter. Habitat loss and degradation are causes for a slow decline, but it is still assessed as Least Concern. Its tendency to stay hidden makes it more often heard than seen.
Temperament
secretive and skulking
Flight Pattern
short rapid wingbeats, low to the ground
Social Behavior
Usually solitary or in pairs, keeping to dense cover. Nests are typically low and well hidden in tussocks, shrubs, or bamboo clumps. Territorial singing males advertise from concealed perches; pairs maintain small territories during breeding.
Migratory Pattern
Partial migrant
Song Description
Song is a loud, ringing series of clear notes and buzzy trills that can accelerate, often delivered from deep cover. Calls include sharp ticks and thin seep notes used for contact and alarm.
