The African reed warbler or African marsh warbler (''Acrocephalus baeticatus'') is an Old World warbler in the genus ''Acrocephalus''. It breeds in much of Africa south of the Sahara. It is migratory within the continent, with southern breeding population moving to the tropics in the southern hemisphere’s winter. This bird is sometimes considered to be a subspecies of the Eurasian reed warbler, ''Acrocephalus scirpaceus''. This is a common species of marshy areas, with reeds sedges or rank vegetation. When not breeding, it may enter gardens. ==Description== The African reed warbler is a plain smallish bird with a somewhat flattened forehead, 13 cm long and weighing around 11 gm. Its upperparts are rich brown, and it has a weak white supercilium. The underparts are white, with a rufous wash to the flanks. The strong pointed bill has a slightly downcurved upper mandible; it is dull yellow with a yellower base. The legs are black and the eyes are brown. The sexes are similar in appearance, but the juvenile has a rufous rump. The song is a slow, chattering ''jit-jit-jit'' with typically acrocephaline whistles and mimicry added. It is indistinguishable from reed warbler except for the species that are mimicked. This species can only be safely distinguished from the reed warbler in the hand. However, that species is usually found in much wetter habitats, and is rare or absent from much of southern Africa. In southern Africa, the main confusion species is the migrant marsh warbler ''Acrocephalus palustris'', and distinguishing these two species is not easy. Marsh warbler is larger, colder brown above, is longer-winged, and has a flatter head profile. It is also found in drier habitats and intersperses more musical phrases in its song. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「African reed warbler」の詳細全文を読む スポンサード リンク
