Old World Warblers are a large group of almost 400 species. Small and difficult to tell apart at first sight, most can be identified by their songs which are often rich, complex and melodious. The genus Sylvia – from Modern Latin silvia, a woodland sprite, related to silva, a wood. – was introduced in 1769 by the Italian naturalist Giovanni Antonio Scopoli. The New World warblers or wood-warblers are a group of small, often colourful, passerine birds which make up the family Parulidae and are restricted to the New World. They are not closely related to Old World warblers or to Australian warblers.
