Vireos
The vireos make up a family (biology), family, Vireonidae, of small to medium-sized passerine birds found in the New World (Canada to Argentina, including Bermuda and the West Indies) and Southeast Asia. "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 color, the smaller species resembling New World warbler, wood warblers apart from their heavier bills. They range in size from the Chocó vireo, dwarf vireo and lesser greenlet, all at around 10cm and 8g, to the peppershrikes and shrike-vireos at up to 17cm and 40g.Forshaw, Joseph & Parkes, Kenneth C. 1991. ''Encyclopaedia of Animals: Birds,'' p. 209. Merehurst Press, London. Distribution and habitat Most species are found in Middle America (Americas), Middle America and northern South America.

Vireo (genus)
''Vireo'' is a genus of small passerine birds restricted to the New World. Vireos typically have dull greenish plumage (hence the name, from Latin ''virere'', "to be green"), but some are brown or gray on the back and some have bright yellow underparts. They resemble wood warblers apart from their slightly larger size and heavier bills, which in most species have a very small hook at the tip. The legs are stout. Most species fall into two plumage groups: one with wing bars and yellow or white eye rings, and one with unmarked wings and eye stripes; however, the Chocó vireo has both wing bars and eye stripes. Sexes are alike in all species except for the black-capped vireo, in which the male's crown is black and the female's is gray. Taxonomy The genus ''Vireo'' was introduced in 1808 by the French ornithologist Louis Jean Pierre Vieillot. The type species was subsequently designated as the white-eyed vireo (''Vireo griseus'') by German ornithologist Hans Friedrich Gadow in 188 ...

Pteruthius
The shrike-babblers are a group of small birds in the genus ''Pteruthius''. They are native to the Indomalayan realm, and were traditionally placed in the family Timaliidae before molecular phylogenetic studies in 2007 found that they were best considered as belonging to the family Vireonidae which was then thought to be restricted to the New World. They were traditionally classified into five species with several subspecies but changes in the status of these species on the basis of the phylogenetic species concept suggest more forms in a cryptic species complex. Most species are found in montane forests, with some species descending down to lower altitudes during the winter. The shrike-babblers range in size from 11.5–20 cm in length and weigh 10-48 g. They are divergent in plumage and size but all possess a stout black hooked bill, short rictal bristles and a distinctive juvenile plumage. They all exhibit sexual dimorphism in plumage, with the males generally brighter. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...

Lesser Greenlet
The lesser greenlet (''Pachysylvia decurtata'') is a small passerine bird in the vireo family. It breeds from northeastern Mexico south to western Ecuador. This is a common species of lowlands and foothills up to altitude, where it inhabits forest canopy and edges, and the crowns of trees in tall second growth or semi-open areas. The nest is a deep cup of dead leaves and spiderwebs attached by the rim to branches high in a tree. The normal clutch is two brown-marked white eggs. The adult lesser greenlet is in length and weighs . It has olive-green upperparts and a pale grey head with a white eye ring. The underparts are white with a yellow tinge to the breast and some olive on the flanks. Young birds are duller and brown above, and have a buff tone to the sides of the head and the breast. There are two races. Nominate ''H. d. decurtatus'' which breeds from central Panama southwards has a green crown to the head, and grey-crowned ''H. d. minor'' occupies the northern part of t ...

Peppershrike
The peppershrikes are two species of passerine bird found in tropical Central and South America. They form the genus ''Cyclarhis'', part of the vireo family. These are heavyset birds with a hooked shrike-like bill. Although sluggish and very vocal, the peppershrikes are still difficult to spot as they feed on insects and spiders in the canopy aloft. Their cup-shaped nest A nest is a structure built for certain animals to hold eggs or young.

Middle America (Americas)
Middle America is a subregion in the middle latitudes of the Americas. It usually includes Mexico, the 7 countries of Central America, and the 13 island countries and 18 territories of the Caribbean. Together with Northern America, they form the continent of North America. Colombia and Venezuela of South America are sometimes included in this subregion. The Caribbean is occasionally excluded from this subregion while Bermuda and The Guianas are infrequently included. Geography Physiographically, Middle America marks the territorial transition between Northern America and South America, connecting yet separating the two.Gonzalez, Joseph. 2004"Middle America: Bridging Two Continents"(ch. 17). ''The Complete Idiot's Guide to Geography.''

Yellow-throated Vireo
The yellow-throated vireo (''Vireo flavifrons'') is a small American songbird. Etymology "Vireo" is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch. The specific ''flavifrons'' is from the Latin words ''flavus'', "yellow", and ''frons'', "forehead". Description Adults are mainly olive on the head and upperparts with a yellow throat and white belly; they have dark eyes with yellow "spectacles". The tail and wings are dark with white wing bars. They have thick blue-grey legs and a stout bill. Measurements: * Length: 5.1-5.9 in (13-15 cm) * Weight: 0.5-0.7 oz (15-21 g) * Wingspan: 9.1 in (23 cm) Habitat and distribution Their breeding habitat is open deciduous woods in southern Canada and the eastern United States. These birds migrate to the deep southern United States, Mexico, the Caribbean, and Central America. They are very rare vagrants to western Europe; there is a September 1990 record from ...

Chocó Vireo
The Chocó vireo (''Vireo masteri'') is a species of bird in the family Vireonidae that was discovered by Paul Salaman in 1991 and described in 1996. It is found in western Colombia and has recently been found in north-west Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. Discovery The Chocó vireo was first observed on August 25, 1991, by Paul Salaman in western Nariño located in southwest Colombia. The site, located at an altitude of 1,500 meters (five thousand feet), was in a narrow strip of intact, very wet forest along the Rio Nambi, in the Chocó region which is famed for its high biological diversity. In early June, 1992, ornithologist Gary Stiles observed and collected this species while working in Alto de Pisones in Risaralda department. The bird was small, a little more than four inches, lightweight at 11.4 grams, and greenish in color with a broad, wide yellowish wing bar. It had a distinctive facial ...
