Oriental Reed Warbler

Acrocephalus orientalis

Also known as Eastern Great Reed Warbler

Oriental reed warblers are noisy, vigorous songbirds that build woven cup nests suspended between sturdy reed stems. Males project a harsh, rhythmic song from prominent perches high in the marsh to defend breeding territories across East Asia. During winter, populations migrate south across Southeast Asia to forage for insects along dense riverbanks and mangrove edges.

Responsible observation
  • Audio identification: Listen for loud, harsh, chatter-like songs echoing from dense vegetation in late spring.
  • Perch scanning: Look toward the upper tips of reed stalks where singing males briefly show themselves.
  • Wetland etiquette: Remain on established trails to avoid damaging sensitive marshland breeding habitat.
