Found in most of Africa, Europe, Middle East, India, and Asia including western Siberia and western China


Oriental Reed Warbler Acrocephalus orientalis is different enough that it has now been recognised as a separate species. Historically, Basra Reed Warbler Acrocephalus griseldis was also sometimes treated as conspecific.


Two subspecies are accepted[1]:

  • A. a. arundinaceus:
  • A. a. zarudnyi:


Dense reed beds beside lakes, rivers and canals.



Nests colonially. A suspended, basket-shaped nest (similar to a Reed Warbler's) at the edge of the reeds near the water.


Long flight outline. Spreads the tail prior to landing. Dives headlong into the reeds. Hops; upright thrush-like posture on the ground.


Song: very loud, harsh and sustained trr, trr, karra, karra karra, gurrk gurkk gurkk, krik krik krik, karra karra karra... etc
