Clamorous reed warbler

The clamorous reed warbler (Acrocephalus stentoreus) is found in south and east Asia and Australasia, although it is migratory in parts of this area. It breeds in dense reed beds and willows that overhang the water.

The adult bird is seven inches in length. The upperparts are brown with an orange tinge, although the rump is pale fawn. It has a pale whitish “eyebrow”. The underparts are buff to white but darker on the flanks. The legs are grey and the eyes are dark brown. Males and females are similar in appearance.

The clamorous reed warbler is a secretive bird, like other reed warblers, and is not often seen except when it becomes “clamorous” as the males sing from prominent positions to defend territories or attract females.

The breeding season varies depending on location. A clutch of three or four eggs is laid in a nest of dead reeds and other plant material in a deep cup shape woven around several reed stems. It is lined with fibres and feathers. Incubation takes up to 14 days and fledging another 14 days after that.
