Moustached Warbler
Acrocephalus melanopogon
The moustached warbler is 12–13 cm (4.7–5.1 in) long, slightly smaller than the similar sedge warbler (Acrocephalus schoenobaenus). The adult has a finely streaked brown back and white underparts. The forehead is flattened, there is a prominent whitish supercilium, grey ear coverts, and the bill is strong and pointed. The sexes are identical, as with most warblers, but young birds are more heavily streaked and have markings on the breast. The song is fast and similar to the sedge warbler and reed warbler, with some mimicry and typically acrocephaline whistles added.

Oriental Reed Warbler
Acrocephalus orientalis
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.
