Various species of small songbirds belonging predominantly to the Sylviidae (sometimes considered a subfamily, Sylviinae, of the family Muscicapidae), Parulidae, and Peucedramidae families of the order Passeriformes. Warblers are small, active insect eaters found in gardens, woodlands, and marshes. The Old World warblers of the family Sylviidae comprise almost 350 species and are intimately related to the thrushes and the Old World flycatchers. Members of the family occur mainly from Europe and Asia to Australia and Africa, but a few of these birds, notably the kinglet (Regulus) and gnatcatcher (Polioptila), live in the Americas. Many warblers of Europe are familiar enough to have received special names, such as the blackcap (Sylvia atricapilla), the whitethroat (S. communis), and the chiffchaff (Phylloscopus collybita). Reed (see photograph), bush, and swamp warblers (Acrocephalus, Bradypterus, Calamocichla, and Cettia) are mostly brown-plumaged and harsh-voiced birds. Among other well-known genera of Old World warblers are the fantail warblers (see cisticola) and longtail warblers (see prinia).
