The Sumatran wren-babbler is a species of bird in the family Pellorneidae. It is endemic to western Sumatra. Its natural habitat is subtropical or tropical moist montane forest.
Region
Sumatra Highlands
Typical Environment
Occurs in the montane forests of western Sumatra, favoring dense, moist understory with thick leaf litter and bamboo or rattan tangles. It is typically found along shaded ravines, mossy slopes, and near trickling streams where invertebrates are abundant. The species keeps close to the ground and uses cover to move between foraging patches. Intact primary forest is preferred, but it may persist in well-structured secondary growth if the understory remains dense.
