The yellow-green vireo (Vireo flavoviridis) is a small American passerine bird. It is migratory breeding from Mexico to Panama and wintering in the northern and eastern Andes and the western Amazon Basin.
The yellow-green vireo was formally described by the American ornithologist John Cassin in 1851 under the binomial name Vireosylvia flavoviridis. [2] The specific epithet combines the Latin flavus meaning "yellow" and viridis meaning "green". [3] The type locality is San Juan de Nicaragua. [4] [5] The yellow-green vireo is now placed in the genus Vireo that was introduced in 1808 by the French ornithologist Louis Pierre Vieillot. [6] [7]
Five subspecies are recognised: [7]
The adult yellow-green vireo is 14–14.7 cm in length and weighs 18.5 g. It has olive-green upperparts and a dusky-edged gray crown. There is a dark line from the bill to the red-brown eyes, and a white supercilium. The underparts are white with yellow breast sides and flanks. Young birds are duller with brown eyes, a brown tint to the back, and less yellow on the underparts. The adult yellow-green vireo differs from the red-eyed vireo in its much yellower underparts, lack of a black border to the duller gray crown, yellower upperparts and different eye color.
Some individuals are difficult to separate, even in the hand, from the similar red-eyed vireo, with which it is sometimes considered conspecific. Its exact status as a passage bird in countries such as Venezuela is therefore uncertain.
The yellow-green vireo has a nasal nyaaah call, and the song is a repetitive veree veer viree, fee’er vireo viree, shorter and faster than that of the red-eyed vireo. This species rarely sings on its wintering grounds.
It breeds from southern Texas (occasionally the Rio Grande Valley) in the United States and the western and eastern mountain ranges of northern Mexico (the Sierra Madre Occidental and Sierra Madre Oriental—also the Cordillera Neovolcanica) south to central Panama. It is migratory, wintering in the northern and eastern Andes and the western Amazon basin. This vireo occurs in the canopy and middle levels of light woodland, the edges of forest, and gardens at altitudes from sea level to 1500 m.
The 6.5-cm-wide cup nest is built by the female from a wide range of plant materials, and attached to a stout twig normally 1.5–3.5 m above the ground in a tree, but occasionally up to 12 m high. The normal clutch is two or three brown-marked white eggs laid from March to June and incubated by the female alone, although the male helps to feed the chicks. The breeding birds return to Central America from early February to March, and most depart southwards by mid-October.
Yellow-green vireos feed on insects gleaned from tree foliage, favoring caterpillars and beetles. They also eat small fruits, including mistletoe berries, and, in winter quarters, those of Cymbopetalum mayanum (Annonaceae) and gumbo-limbo (Bursera simaruba). [8]
The Philadelphia vireo is a small North American songbird in the vireo family (Vireonidae). "Vireo" is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch. The specific philadelphicus is for the city of Philadelphia.
The pine warbler is a small songbird of the New World warbler family.
The white-eyed vireo is a small songbird of the family Vireonidae.
The chivi vireo is a small South American songbird in the family Vireonidae. It was formerly considered a subspecies of the red-eyed vireo. It is usually green to yellow-green in color with off-white underparts, and a gray crown. It has a whitish supercilium extending over its ear coverts, and its lores are dull gray in color. The chivi vireo has nine subspecies. It is found throughout most of northern, eastern and central South America, only being absent from southern Chile and southern Argentina. It inhabits multiple types of habitat across its range, and appears to adjust well to slightly disturbed habitat. The chivi vireo is mainly resident, but at least two of the subspecies inhabiting the south of its range are known to be migratory.
The boat-billed flycatcher is a passerine bird. It is a large tyrant flycatcher, the only member of the monotypic genus Megarynchus.
The rufous-browed peppershrike is a passerine bird in the vireo family. It is widespread and often common in woodland, forest edge, and cultivation with some tall trees from Mexico and Trinidad south to Argentina and Uruguay.
The trilling gnatwren, formerly long-billed gnatwren, is a very small bird in the gnatcatcher family. It found from southeast Mexico south to Ecuador and Amazonia.
The great antshrike is a passerine bird in the antbird family, Thamnophilidae. It is the only member of the genus Taraba. It is a resident breeder in the tropical New World in southern Mexico, Central America, Trinidad and South America down to northern Argentina and southeastern Brazil.
The dusky-capped flycatcher is a passerine bird in the tyrant flycatcher family. It breeds in forest and other woodland from southern Arizona, as well as the Chisos Mountains, Texas, south to northern Argentina and on Trinidad. It is resident in most of its range, but American breeders retreat to Mexico in winter.
The grassland yellow finch is a small passerine bird. Despite its name, it is not a finch, but is a seedeater. These were formerly united with the buntings and American sparrows in the Emberizidae, but are now known to be tanagers.
The streaked flycatcher is a passerine bird in the tyrant flycatcher family.
The white-flanked antwren is an insectivorous bird in the antbird family, Thamnophilidae.
The Arizona woodpecker is a woodpecker native to southern Arizona and New Mexico and the Sierra Madre Occidental of western Mexico. The species' northernmost range in southeastern Arizona, extreme southwestern New Mexico, and northern Sonora is the region of the Madrean Sky Islands, a region of higher Sonoran Desert mountain ranges.
The yellow-winged vireo is a small passerine bird. It is endemic to the highlands of Costa Rica and western Panama.
The lesser greenlet is a small passerine bird in the vireo family. It breeds from northeastern Mexico south to western Ecuador.
The common tody-flycatcher or black-fronted tody-flycatcher is a very small passerine bird in the tyrant flycatcher family. It breeds from southern Mexico to northwestern Peru, eastern Bolivia and southern, eastern and northeast Brazil.
Cassin's vireo is a small North American songbird, ranging from southern British Columbia in Canada through the western coastal states of the United States. This bird migrates, spending the winter from southern Arizona to southern Mexico.
The Yucatan vireo is a species of bird in the family Vireonidae.
Vireo is a genus of small passerine birds restricted to the New World. Vireos typically have dull greenish plumage, 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.
The western flycatcher is a small insectivorous bird in the family Tyrannidae. It is native to western North America, where it breeds in the Rocky Mountains and Pacific Coast forests and mountain ranges from California to Alaska, and winters in Mexico.
