Brown-flanked Bush Warbler

The brown-flanked bush warbler (Horornis fortipes), also known as the brownish-flanked bush warbler, is a species of bush-warbler of the family Cettiidae. It was formerly included in the "Old World warbler" assemblage. It is found in Himalayas, South China and Southeast Asia. Horornis fortipes is the scientific name used by the project species list. The description here uses general species-wide information and does not imply that every trait has been documented separately in Vietnam.

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).
