The New World warblers or wood-warblers are a group of small, often colorful, passerine birds that make up the family Parulidae and are restricted to the New World. The family contains 120 species. They are not closely related to Old World warblers or Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores.
The eastern olivaceous warbler, known simply as the olivaceous warbler when its western relative is referred to as the 'Isabelline warbler', is a small passerine bird with drab plumage tones, that is native to the Old World. For the most part it breeds in southeastern Europe, the Middle East and adjacent western Asia, and winters in the northern Afrotropics.

It is monotypic in its genus. It is found in Burundi, Democratic Republic of the Congo, Kenya, Rwanda, Tanzania, Uganda, and Zambia. Its natural habitat is swamps. It is threatened by habitat loss.
The Anjouan brush warbler is a species of Old World warbler in the family Acrocephalidae. Clements lumps this bird into the Malagasy brush warbler N. typica. This is supported by the IUCN, whereas the IOC recognizes it as a valid species. It is endemic to the Comoros and Mayotte.
The Santa Marta warbler is a species of bird in the family Parulidae. It is endemic to the Santa Marta Mountains in Colombia.
The golden-browed warbler is a species of bird in the family Parulidae, the New World warblers. It is found in El Salvador, Guatemala, Honduras, and Mexico. Its natural habitat is subtropical or tropical moist montane forests. The species was described by Jacob Post Giraud, Jr. in 1841.
The grey-headed warbler is a species of bird in the family Parulidae. It is endemic to Venezuela.
The Pirre warbler is a species of bird in the family Parulidae. It is found in the borderline area of Panama and Colombia . Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
The three-banded warbler is a species of bird in the family Parulidae. It is found in Ecuador and Peru. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
The three-striped warbler is a species of bird in the family Parulidae. It was previously considered conspecific with the Tacarcuna warbler and the black-eared warbler. This bird is found in South America from Venezuela to Peru. The Yungas warbler was previously considered a subspecies.
The crested tit-warbler is a species of bird in the family Aegithalidae. It is found in China and possibly India. Its natural habitat is boreal forest. It generally has a red hint to it and a bit of blue on, or near, its wings. The tail is of an emerald green colour.
The fan-tailed warbler is a New World warbler in the genus Basileuterus that lives along the Pacific slope from northern Mexico to Nicaragua. Vagrant records exist for Arizona, New Mexico and Texas. It is yellow on its throat and underparts with a tawny wash on its chest. The head is gray with a black-framed yellow crown and white around the eyes. The undertail coverlets are white. They are 5.8-6.3 in (14.5–16 cm) long and have pleasant, upslurred song. Fan-tailed warblers live in and at the edge of evergreen and semideciduous forest, especially near ravines. They eat ants, especially army ants, and are seen hopping around on either the forest floor or close to it. They are found alone or in pairs.
The chestnut-capped warbler is a New World warbler native from Guatemala to Venezuela. It was split from the rufous-capped warbler as a distinct species by the IOC in 2021.
Myiothlypis is a genus of New World warblers, best represented in Central and South America. This is one of only two warbler genera that are well represented in the latter continent. All of these species were formerly placed in the genus Basileuterus.
The Roraiman warbler is a species of passerine bird in the new world warbler family Parulidae. It is known to associate with Tepui rainforest ecosystems and is found in southern Venezuela, western Guyana, and adjacent areas of northern Brazil. The bird has been periodically granted full species status, although it has also been occasionally considered a subspecies of two-banded warbler. Based on the population's physically disparate distance from the nominate species, vocal differences, and slight differences in plumage, several authorities consider the Roraiman warbler independent. Recent genetic evidence also indicates the birds of northern South America are significantly diverged from the two-banded warbler populations in the Andes.
