Descriptive notes.Basra Reed Warbler is treated as a subspecies of Great Reed Warbler, although some scientists, who have studied the taxonomy of large Palearctioc Acrocephalus, believe that considerable morphological differences warrant is full separation as a full species. Compared with Great, Eastern Great and Clamorous Reed Warbler, is much smaller-sized in wings, tail and in tarsus, with combination of rather short and slender bill. Upperparts more or less uniform cold olivaceous-brown, and generally tends to show some tonal contrast with darker remiges, chiefly rectrices. Underparts whiter than on above three species, with restricted cream-yellow tinge on flanks, and has awhiter throat. Supercilium whites, and quite prominent, extending well behind eye, and often with well-emphasised dark eye-stripe.Habitat.In both cool and warm and arid and moist clicates. Prefer to winter in moist habitat with scattered thickets, tall grass, and bulrushes or in maize fields, apparently more closely associated with water.Food and Feedingmainly insects, sith some spiders, snails, and small vertebrates, some fruits and berries and berries outside breeding season.Breeding.No further information.Movements.All popullations migratory.
