Chinese Bush Warbler

The Chinese bush warbler (Locustella tacsanowskia) is an Old World warbler in the family Locustellidae. The species was first described by Robert Swinhoe in 1871. It breeds in the East Palearctic (East Siberia to Tibet and South China); it winters to Northeast India, Yunnan and Southeast Asia. Its natural habitat is temperate forests. Locustella tacsanowskia is the scientific name used by the project species list. (Wikipedia, general species account).

This species belongs to a group of small, active songbirds that generally search foliage, stems or ground cover for insects and other small invertebrates. Many are easier to detect by voice than by sight, particularly in dense vegetation, and closely related forms may require calls, season and range for confident identification. These are group-level ecological notes, not Vietnam-specific breeding measurements (general warbler ecology).
