Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller number of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.
Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus.
The Acrocephalus warblers are small, insectivorous passerine birds belonging to the genus Acrocephalus. Formerly in the paraphyletic Old World warbler assemblage, they are now separated as the namesake of the marsh and tree warbler family Acrocephalidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with marsh warbler and reed warbler.
The hooded warbler is a New World warbler. It breeds in eastern North America across the eastern United States and into southernmost Canada (Ontario). It is migratory, wintering in Central America and the West Indies. Hooded warblers are very rare vagrants to western Europe.

The Bornean stubtail is a species of bird in the cettiid warbler family Cettiidae. It is endemic to the island of Borneo, where it inhabits forest floors and undergrowth in montane forests at elevations of 750–3,150 m (2,460–10,330 ft).
