The aberrant bush warbler is a species in the bush warbler family, Cettiidae. It was formerly included in the "Old World warbler" assemblage.
Region
Himalayas and northern Southeast Asia
Typical Environment
This species ranges from the Himalayan foothills through northeastern India, Bhutan, Nepal, and Myanmar into southern China and the mountains of northern Southeast Asia. It favors dense shrubbery, bamboo thickets, forest edges, and regenerating secondary growth. Birds often keep close to the ground or mid-story, especially along ravines and streamside tangles. Many populations are largely sedentary, with some making local altitudinal movements following seasons.

The aberrant bush warbler is a small, skulking warbler of dense undergrowth, now placed in the family Cettiidae after formerly being grouped with the Old World warblers. It is heard more often than seen, delivering sharp, insect-like trills from low cover. Several subspecies occur across the Himalayas and into Southeast Asia, with subtle regional plumage and vocal differences.
Temperament
secretive and skulking
Flight Pattern
short rapid wingbeats, stays low in cover
Social Behavior
Usually solitary or in pairs, keeping to dense undergrowth where it forages quietly. Nests are well concealed, typically low in shrubs or grass tussocks, with both parents attending the young. Territorial singing males deliver persistent songs from within cover.
Migratory Pattern
Partial migrant
Song Description
Song is a rapid, high-pitched series of trills and buzzy, insect-like notes, often delivered repeatedly from hidden perches. Calls include sharp ‘tck’ or ‘tsp’ notes used as contact or alarm sounds.
