Vireonidae

The vireos, greenlets and others make up the family Vireonidae. They are small to medium-sized passerines restricted to the New World. 'Vireo' is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch.

They are typically dull-plumaged and greenish in colour, the smaller species resembling wood warblers apart from their heavier bills. They range in size from the Chocó Vireo, Dwarf Vireo and Lesser Greenlet, all at around 10 centimeters and 8 grams, to the peppershrikes and shrike-vireos at up to 17 centimeters and 40 grams.

Most species are found in Middle America and northern South America. Thirteen species of true vireos occur farther north, in the United States, Bermuda and Canada; of these all but Hutton's Vireo are migratory. Members of the family seldom fly long distances except in migration. They inhabit forest environments, with different species preferring forest canopies, undergrowth, or mangrove swamps.

The resident species occur in pairs or family groups that maintain territories all year (except Hutton's Vireo, which joins mixed feeding flocks). Most of the migrants defend winter territories against conspecifics. The exceptions are the complex comprising the Red-eyed Vireo, the Yellow-green Vireo, the Black-whiskered Vireo, and the Yucatan Vireo, which winter in small wandering flocks.

The nests of many tropical species are unknown. Of those that are known, all build a cup-shaped nest that hangs from branches. The female does most of the incubation, spelled by the male except in the Red-eyed Vireo complex.

All members of the family eat some fruit but mostly insects and other arthropods. They take prey from leaves and branches; true vireos also fly-catch, and the Grey Vireo takes 5 percent of its prey from the ground.There are, according to the IOC, 63 species of Greenlets, Vireos and allies (all in the new world) in the family Vireonidae; they are:

Vireos, Greenlets & Allies Vireonidae
