Vireos
The vireos make up a 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. The family contains 62 species and is divided into eight genera. "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 wood warblers apart from their heavier bills. They range in size from the Chocó vireo, dwarf vireo and lesser greenlet, all at around 10 cm and 8g, to the peppershrikes and shrike-vireos at up to 17 cm 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 and northern South America. Thirteen species of true vireos occur farther north, in the United States, Bermuda and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 New World warbler, 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 Pierre Vieillot. The type species was subsequently designated as the white-eyed vireo (''Vireo griseus'') by German ornithologist Hans Friedrich ...

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 generally have an anisodactyl 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 order of birds and one of 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 suborders: New Zealand wrens; Suboscines, primarily found in North and South America; and songbirds. Passerines originated in the ...

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 phylogenetics, 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 bird migration, 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 pluma ...

Cyclarhis
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 nests can likewise be found high in the trees. Taxonomy The genus ''Cyclarhis'' was introduced in 1789 by the English naturalist William Swainson to accommodate a single species, the rufous-browed peppershrike, which is therefore the type species. The genus name is from the Ancient Greek Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek ... ''kuklos'' meaning "circle" and ''rhis'', ''rhinos'' meaning "nostrils". The ...

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 ...

Middle America (Americas)
Middle America is a subregion in the Northern Hemisphere tropics of the Americas. It usually includes Mexico, the seven 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 Caribbean South America are sometimes included in this subregion. The Caribbean is occasionally excluded from this subregion while 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 reco ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion of the Americas. South America is bordered on the west by the Pacific Ocean, on the north and east by the Atlantic Ocean, and to the south by the Drake Passage; North America and the Caribbean Sea lie to the northwest. The continent includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territory, dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one administrative division, internal territory: French Guiana. The Dutch Caribbean ABC islands (Leeward Antilles), ABC islands (Aruba, Bonaire, and Curaçao) and Trinidad and Tobago are geologically located on the South-American continental shel ...
