The marsh warbler is about 13 cm long and has a wingspan of 17 to 21 cm. The weight is about 11 to 14 grams. The upperparts are greyish brown, the underparts are yellowish white. The small bird has a whitish throat and a pointed beak. Males and females have the same colouring. The marsh warbler moves skilfully in dense vegetation and imitates the calls and songs of other bird species, which it mixes with typical reed warbler phrases. It can often be heard in late twilight and at night.
The marsh warbler lives in dense reeds, bushes and crop fields near water bodies.
