Description

It is a large warbler, 18–20 cm long with a wingspan of 23–26 cm. The plumage is brown above with a paler rump and whitish tips to the tail feathers. The underparts are whitish below, browner on the flanks and undertail-coverts. There are narrow greyish streaks on the throat and breast. It has a dark eyestripe and a whitish stripe above the eye. The fairly long, heavy bill is brownish above and pink below with a bright orange gape. The feet are grey. It is slightly smaller, slenderer and shorter-winged than the great reed warbler. Its tail is shorter and more square-ended than that of the clamorous reed warbler (A. stentoreus) and it has a slightly longer primary projection and a slightly shorter and thicker bill. The pale tip to the tail separates it from both species. The song is a mixture of warbling phrases and guttural, croaking notes. It is given from a prominent perch such as the top of a reed stem or bush. The bird also has a loud, harsh chack call.

Feeding Habits
Oriental Reed Warbler primarily consumes insects, arachnids, and small snails, with occasional small vertebrates. Nestlings in Honshu feed on a variety of insects and other invertebrates and sometimes fish fry or young frogs. Typical foraging occurs in dense vegetation, akin to the A. arundinaceus.
Habitat
The oriental Reed Warbler typically inhabits expansive wetlands, with a preference for dense reedbeds predominantly composed of Phragmites. Its habitat extends through various lowland aquatic environments, including lakesides, coastal marshes, estuaries, riversides, and ditches. Additionally, it frequents grasslands, paddy fields, and areas with scrub vegetation while foraging for its invertebrate prey. Adaptability is evident as the oriental Reed Warbler utilizes fragmented reedbeds within agricultural landscapes, such as rice paddies, and occasionally reed stands near residential zones. This species is found up to elevations of 1000 meters, with non-breeding habitats extending to similar wetland regions in Southeast Asia.
Dite type
Insectivorous

Distribution Area

The breeding range covers southern Siberia, Mongolia, northern, central and eastern China, Korea and Japan. It winters in north-east India and across South-east Asia to the Philippines and Indonesia, occasionally reaching New Guinea and Australia. It has occurred as a vagrant in Israel and Kuwait. It breeds mainly in reedbeds and can also be found in marshes, paddy fields, grassland and scrub where it forages for insects and other invertebrates.
