Parulidae – New World Warblers

Mangrove Warbler Setophaga petechia ©Clayton Burne Website

The Parulidae or New World warblers (sometimes wood-warblers) are a family of small, often colourful, passerines, which are restricted to the New World. They are not closely related to Old World warblers or to Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores.

It is likely that this group originated in northern Central America, where the greatest number of species and diversity between them is found. From there they spread north during the interglacial periods, mainly as migrants, returning to the ancestral region in winter. Two genera, Myioborus and Basileuterus seem to have colonised 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 Linnaeus in 1758 named the Northern Parula as a 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.

All the warblers are fairly small. The smallest species is Lucy’s Warbler Oreothlypis luciae, at about 6.5g and 10.6cm. The Parkesia waterthrushes, the Ovenbird, the Russet-crowned Warbler and Semper’s Warbler, all of which can exceed 15cm and 21g, might 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. In contrast, resident tropical species, which pair for life, show little if any sexual dimorphism. There are exceptions. The Parkesia waterthrushes and Ovenbird are strongly migratory, but have identical male and female plumage, whereas the mainly tropical and sedentary yellowthroats are sexually dimorphic.

  • Visualizing Western Warbler Songs

    Website
    Those of you who began birding before 1980 will probably remember that the field guide of choice was A Guide to the Field Identification of Birds of North America now usually referred to as the Golden Guide. Produced by Golden Press, it was the best comprehensive guide to North American Birds at the time. It was among the first field guides to place illustrations next to text and include range maps in the margins. It was one of the first pocket sized field guides to illustrate birds in natural and varied settings. And then there were those wonderful sonograms…
