The New World warblers or wood-warblers are a group of small, often colorful,

arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores
.

This group likely originated in northern

Myioborus and Basileuterus, seem to have colonized South America
early, perhaps before the two continents were linked, and together constitute most warbler species of that region.

The scientific name for the family, Parulidae, originates from the fact that

tit, Parus americanus, and as taxonomy developed, the genus name was modified first to Parulus and then to Parula
. The family name derives from the name for the genus.

Cladogram showing the relationships between the genera[1][2]

The family Parulidae was introduced for the New World warblers in 1947 by American ornithologist

junior synonym of Setophaga.[2]

The family was formerly thought to be

Calyptophilidae, the wrenthrush, and the Phaenicophilidae.[5]

A

monotypic genera. The changes have generally followed the recommendations of the authors of the study except in a few cases where the proposed genera were split to separate basal species from their proposed conspecifics.[1][2]

A large clade that included the 29 species then placed in the genus Dendroica, also included four species of Parula, one of the three species of Wilsonia and the

priority over Dendroica Gray, 1842, Wilsonia Bonaparte, 1838, and Parula Bonaparte, 1838.[1][2]

The species that had traditionally been placed in Basileuterus formed two clades. One group retains the genus name as it includes the golden-crowned warbler, the type species for the genus. The other larger group, now with 18 species, is placed in the resurrected genus Myiothlypis Cabanis, 1850, as it contains the type species, the black-crested warbler.[1][2]

The genus

Myioborus containing the whitestarts remained unchanged after the reorganization but six genera were no longer used: Dendroica, Ergaticus, Euthlypis, Parula, Wilsonia and Phaeothlypis.[1][2]

Extant Genera

The family Parulidae now contains 120 species divided into 18 genera.[1]

Former species

Some species that were previously placed in the Parulidae have been moved to other families:[1][2][4]

Description

All the warblers are fairly small. The smallest species is

Parkesia waterthrushes, the ovenbird, the russet-crowned warbler, and Semper's warbler
, all of which can exceed 15 cm (5.9 in) and 21 g (0.74 oz), may be considered the largest.

The migratory species tend to lay larger clutches of eggs, typically up to six, since the hazards of their journeys mean that many individuals will have only one chance to breed. In contrast, the laying of two eggs is typical for many tropical species, since the chicks can be provided with better care, and the adults are likely to have further opportunities for reproduction.

Many migratory species, particularly those which breed further north, have distinctive male plumage at least in the breeding season, since males need to reclaim territory and advertise for mates each year. This tendency is particularly marked in the large genus Setophaga (formerly Dendroica). In contrast, resident tropical species, which pair for life, show little if any sexual dimorphism, but exceptions occur. The Parkesia waterthrushes and ovenbird are strongly migratory, but have identical male and female plumage, whereas the mainly tropical and sedentary yellowthroats are dimorphic. The Granatellus chats also show sexual dimorphism, but due to recent genetic work, have been moved into the family Cardinalidae (New World buntings and cardinals).

The name warbler is a misnomer for the New World group of warblers established before the family was split from the Old World warbler in the 1830s. The Random House Dictionary defines "to warble" as "to sing with trills." Most New World warblers do not warble, but rather "lisp, buzz, hiss, chip, rollick, or zip."[6]
