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:
- 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
