The Taiwan bush warbler is a species of Old World warbler in the family Locustellidae. It is found only in Taiwan. Its natural habitat is undergrowth and grassland 1,200–3,000 m (3,900–9,800 ft) in elevation. It was first recorded in 1917 and named as a distinct species in 2000. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
Region
East Asia
Typical Environment
This species is confined to Taiwan’s central and northern mountains, where it occupies dense grasslands, dwarf bamboo, and shrub thickets along forest edges. It favors secondary growth and scrubby clearings, especially with tangled ground cover. Birds keep low to the ground, moving through tussocks and root tangles to remain concealed. It can be locally common where suitable undergrowth persists and is least seen in heavily disturbed, open areas.

The Taiwan bush warbler is a skulking Old World warbler found only in Taiwan’s montane undergrowth. First noted in 1917, it was only recognized as a distinct species in 2000. Its song is an insect-like, repetitive trill delivered from dense cover. Despite its restricted range, it is assessed as Least Concern due to stable populations in suitable habitat.
Temperament
solitary and secretive
Flight Pattern
short rapid wingbeats with low, fluttering dashes between cover
Social Behavior
Usually encountered alone or in pairs during the breeding season. Nests are placed low in dense grass or bamboo, concealed near the ground. Males sing persistently from hidden perches to defend territories and attract mates. Parental care is shared, with both adults remaining close to the nest site.
Migratory Pattern
Resident
Song Description
A repetitive, insect-like trill or ticking series, even-paced and sustained, often delivered from within dense vegetation. Calls include sharp ticks and soft churrs, aiding contact while staying concealed.
