Small, pallid olive-gray warbler. Very similar to other Iduna and Acrocephalus species. Note its long and slender bill and prominent pale wing panel. Pumps its long tail continuously as it flits around in bushes and trees after small insects. Found in dry Mediterranean and semi-arid zones; strong connection with Tamarix bushes. Call is a dry and harsh “chack.” Song is a repeating scratchy sequence.
