These relatively large warbler-like birds are found mainly in Europe and Asia, but some are found in Africa and Australasia. On islands in the Pacific many different species have evolved. They are usually found in open woodlands or grassy environments. Most are rather plain olivaceous brown above with much yellow to beige below.
Genus Acrocephalus
Rather drab brownish warblers usually associated with marshes or other wetlands. Many species have a relatively flat head profile, which gives rise to the scientific name. Species breeding in temperate regions are strongly migratory.
