Acrocephalus
The Acrocephalus warblers are small insectivorous passerine birds belonging to the genus Acrocephalus of the Old World warbler family Sylviidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with Marsh Warbler and Reed Warbler, especially in North America, where it is common to use lower case for bird species.
These are rather drab brownish warblers usually associated with marshes or other wetlands. Some are streaked, others plain. Almost all are migratory.
Many species have a flat head profile, which gives rise to the group's scientific name.
Species breeding in temperate regions are strongly migratory.
